REMOVING CUMMINS 6.7 EGR & DPF “DO NOT REMOVE”
I promised you the inside scoop on what’s going on with the 2007 Dodge Ram 2500/3500 Cummins Diesel 6.7l check engine light, poor fuel economy and other “issues”.
Over the past year many of you loyal Dodge owners have suffered (as noted in your comments) and here is the video on the subject of REMOVING the Cummins 6.7 diesel EGR, as told to me by some very experienced and highly respected Dodge-trained technicians.
[youtube=http://www.youtube.com/watch?v=Ypd46Da7KoM]
The 6.7 diesel EGR is a federally mandated piece of equipment, which will throw codes and fail any emissions inspection upon removal. in fact. the truck will flat out, not run correctly. Basically, DO NOT REMOVE or Attempt to remove the EGR or DPF of the Cummins 6.7 diesel, here’s why…
Given that this is the first time a diesel truck has been presented with such strict emissions requirements, all three of the BIG 3 have found various ways to accomodate the need to reduce pollutants. Cummins chose this route to designing a better system, without giving up power. Now granted, there have been a multitude of revisions to the computer, called “flashs”, which have re-aligned various configurations from timing, heat, pressure and acceleration.
The overwhelming theme that has come from my research into the 6.7 diesel EGR is that there are currently NO MOPAR approved or after-market chips, kits or computer programs available to “trick” the EGR. In fact, the programming itself is said to be so complex, that every vehicle has it’s own fingerprint, and the truck actually “learns” the owner’s driving habits to help it perform at optimum levels. However, this includes a variety of driving experiences, loads and lots of miles.
Unlike the 5.9 Cummins, which offered alot of opportunity for customization (and little emissions regulation) the only thing one might add to this truck is a cold air intake, which will improve horsepower by 20mph, on a truck that already leaves patches in the asphalt. The desire for improved fuel economy will be minor with the CAI.
And now for the word on the Cummins 6.7 diesel DPF. Many of you have asked about removing the entire exhaust system, replacing it with a straight back and living with the codes. Here’s the word from the “guys that know them best…”
[youtube=http://www.youtube.com/watch?v=kQvgx1cxcaI]
TIPS for driving the NEW 6.7.
1. Don’t let it idle. Stop and go driving fails to build up enough HEAT to set the Regeneration system into action, and it’s the high heat (temp.) that burns out the waste in the DPF, which keeps it from “filling”. When the DPF is “FULL” it sets off the dash lights and requires a trip to the dealership for a flash. If you have to toodle around town, drop out of 6 speed. Dropping down a gear or two will hurt your fuel economy, but it will allow the engine to force itself into REGEN mode, when you aren’t pulling a heavy load. It sounds dumb, but this truck is made to be worked, HARD. HEAVY loads. Even small business, pulling a trailer on short runs, isn’t working this truck long and hard enough to keep the heat up.
2. HAUL **s. If you are going to run it high RPM’s, you need to keep it going for a steady period of time. Putting a trailer on it once a week may not be enough to “clear” the REGEN, unless your weekend warring constitutes a good long drive.
3. WATCH the FUEL. More than one person on this site has accidentally put LOW sulfur into his 6.7l not realizing that it’s not all the same. Some stations offer LOW and ULTRA LOW. because earlier models can digest the LOW stuff. NOT SO THE 2007 DODGE Cummins 6.7 Diesel, FORD or GMC. One wrong fill can set you back LOTS of money! The entire system has to be removed, cleaned and reinstalled. SO, TAKE a minute to check the posting on the pump, and if you don’t see it, ASK before you fuel, you can’t drive off this problem, it makes matters worse! The goverment has a great website on fuel standards; New diesel technologies have improved performance and efficiency, reduced tailpipe emissions, vibrations, and noise of diesel vehicles. Ultra-low sulfur diesel (ULSD), available beginning in 2006, is cleaner burning and allows diesels to be equipped with more-effective controls for reducing particulates and smog-forming nitrogen oxide (NOx) emissions.
So, there you have it. Thanks to my friends in the shop.
P.S. Note: Rumor has it, Dodge will not warranty any part of the truck if the dealer service technicians find evidence of modification, disabling of the exhaust or alterations of the 6.7 diesel emissions equipment, etc. One note in the computer to Dodge headquarters, and your vehicle could be permanently banned from future warranty work of ANY kind.

I might have put a half tank of the low sulfur diesel in my 07 Dodge 6.7 cummings and then drove it almost 300 miles to get home towing a travel trailer. Have I done damage that you describe? What are the symptons? Bruce

I am having a problem with acceleration with my 6.7L, it seems to starve for fuel(Engine bogs Down during acceleration). when I kill the engine and restarted it it goes away for a while, then starts doing it again. any ideas??????

It’s relitively easy to remove the emissions ‘garbage’ on these motors now. it takes a little money, but if you drive enough it pays for itself. the egr system puts soot back into your motor. i have pulled my intake horn off and there is massive amounts of soot build up in there. an intake horn should have a polished look, not a soot build up. the cummins motor is known to be 500,000+ mile motor. do you really think when you are pooring a coarse material through the intake that you will see that many miles? you might as well put a handful of sand in your intake every time you start your motor.

This is what I sent Dodge. Still can’t speak to anyone until after Monday holiday.
Message sent to Dedge.com
When we picked up our truck from the Klamath Falls, OR Dealership on August 25, the Catalytic warning starting acting up. A mechanic contacted the Medford Dodge dealership who stated it would not cause the car to disable and to run it at high speed for 45 min. I also called to verify that and was told the truck would not disable. The Dodge manual also states this. But on Aug 29, my husband and daughter were almost killed when the truck shut itself off and my Husband lost power steering and brakes going around a curve at HWY speed with no warning whatsoever. The sheriff came out to help my family afterward. This should not have happened. The GM here at Lithia stated the particulate filter became clogged, but no one can see our truck for more than a week or more because of only having 1 diesel mechanic. We now again a second time have to use a rental vehicle that we have to pay for. Dodge needs to know about this issue. We were never told the electrical in our truck had to be “reflashed” to account for this problem—although we’ve been at 2 different dealerships for scheduled maintenance. Before all this happened we had a “check engine” light on for weeks and had an appt with the Medford Dealership on Sept 3 to have it fixed, before our truck gave out) I need a quick response from Dodge because we are without a vehicle and want to know why this information is not being sent to consumers as a potential threat to safety.

I traded my 5.9 2005 diesel for a 2008 6.7. The codes started showing up in less than 2 weeks. They played around with my new truck, cleaned turbo this and that had my truck back and at 1902 miles my check engine came on again. Dumb ass mechanic for Dodge said I needed a new turbo. Got new turbo and now my mileage sucks worse. I am filing a lawsuit with a lemon law firm, but I need two more check engines light before they will take action. The whole problem is Dodge is trying to make 2010 emissons too fast. The problem is with the DPF (diesel particulate filter) plugging up. This filter is under your truck in exhaust line and looks like a football on steriods. Miss my 2005. No more Dodge for me!!!!!!!!!!!!
Comment by Daryl — September 5, 2008 @ 11:44 pm
SAFETY ALERT!!!!We purchased our new Dodge diesel 6.7 about 14 months ago and right away the check engine light began showing, We have brought it in for repairs at least 5 times, and twice now most of the exhaust system has been replaced with new particulate filters. The last repair took over three weeks apparently because of parts on backorder. We had driven the vehicle about 250 miles since that repair with most of it up to Lost Trail Pass on the border of Idaho and Montana. The engine seemed to be running rough for some of that drive so we stayed overnight before the last part of the climb up the pass to over 7000 feet elevation. Good thing we did not go over that pass at 11pm because the next morning the engine totally cut out as we were headed down the pass. My foot was on the accelerator and we were going about 50 mph. That pass is bordered with steep cliffs and drop offs, and we could easily have gone off the road. When the engine failed we had only a few seconds to brake hard before the steering and brakes failed to respond. The deep sandy shoulder forced the truck to a stop. We had the truck towed about 100 miles to the Lithia dealer in Missoula. Their mechanics have reported that they can’t find anything wrong with the truck. I called Crystler and demanded they broadcast to all locations the potential for fatal accidents with this vehicle, but they will not give out any contact information for anyone higher up than the call center which seems like in India. I intend to call the authorities in the government with traffic safety, and then pursue the lemon law with getting Crystler to buy back the truck. THIS TRUCK IS DANGEROUS!!!!!!

What about removing the cat converter on a 2007 Dodge 6.7L Cummins? Good, Bad… whats you take on it? Would I pick up more HP and better MPG?
Comment by Steve Kaiser — September 18, 2008 @ 12:03 pm
i just bought 2008 6.7l, my check eng.light came on twice and was in the shop twice in 2 days. before i drove it off the lot it wouldnt run, the next day i went to pick it up and they stated it was a censor.i started the truck, and low and behold it wouldnt run again.they got me a rental car and keept it again, the next day stated to me it was a sensor,it finaly ran,i was told to punch the fuc!!!! hell out of it all the time.but the manuel states not to and to not drive over 50mph,the told me to drive like hell and as fast as i want cuz this engine needs it and not to worrie,the sales manager is a some what friend,said dont worrie if it blows up he will get me a new truck and not a repaired truck.
Comment by etchy — September 19, 2008 @ 7:30 pm
Yeah I have an 08 also, shame epa thinks catching the emmissions (black soot or smoke) in a steel can and ruining fuel economy in an attempt to incinerate the visable soot is a solution , if these are the best ideas they can come up with then we are all in big trouble. Is it just too diffacult to tune the motor to be more efficient and burn cleaner, the answer is no its not ,but we wont make any money or get that big promotion. This country needs real leadership in these positions not someone looking for a raise.
Comment by Danny O. — September 22, 2008 @ 6:59 pm
I purchased a 2007 6.7 because my Dad has a 5.9 that gets 22mpg. When new it got about 13 mpg city and 16.8 mpg highway. Now with 19,000 miles and 3 to 4 trips to the dealer (check engine 3 times, entire electrical system shut down 2 times (had to disconect batterys to reset), and truck running rough(turned key off to fix) now fuel mileage is 10.9 mpg in town and 13 to 14 highway. I never thought I would have a $50,000 truck that I had to work on. Dodge needs to do something, I feel cheated……
Comment by Shane Simmons — September 28, 2008 @ 4:36 am
I traded a 2005 3500 in on a 2008 2500 and it has been nothing but trouble.I have had the truck in the shop 6 times First time was at 1200 miles.I have been stranded 3 times and had to get towed in.One time i was pulling a 38ft. fith wheel and the truck just decided to shut off .If i would have been coming down a mountain it could have been deadly to me and my family.I miss my 2005.I have always been a dodge guy but this is the last dodge for me or anyone else that i know or come in contact with wanting to buy a dodge.The problem is that chrysler dont seem to want to do anything about this problem.I am as of today starting the lemon law.I hope others will do the same.
Comment by Anthony Brady — October 2, 2008 @ 2:44 pm
everything dodge makes is junk.MY 2007 6.7 had 2 turbos replaced before 17,000 miles.I got about 400 miles per 35 gallons of diesel. and thats a 2500 2wd regular cab 6 speed manual.unloaded and driving below speed limit. had my ecm replaced twice.8 total check engine lights.mind is now a lemon.p.s. as a car salesman for dodge.get rid of your 6.7 they have terrible resale value

im having same trouble as everyone else on this site with my 08 cummins. is there a class action lawsuit that i could join.

i just bought a 6.7 did not know of problems , i only went by previous cummins
rep. work all the time and had not heard anything about problems.
Comment by spencer king — November 14, 2008 @ 2:46 am
i have a 2007 3500 and have had it in the shop too many times to remember still having problems and have been told its the turbo too. sounds to me like it doesnt need a cleaning like ive been told. im tied of the rough running and having to shut it off and start it 5 times. Is there anything that will actually fix this thing
Comment by corrie s — November 21, 2008 @ 3:16 am
I own a 2007 6.7 2500 piece of garbage and as a dealer myself am embarassed to admit that. A total of 11 trips to service, new parts, cleanings, etc…. Chrysler still refused to respond to my situation until recently. It took a traffic accident when our vehicle stalled, my wife and 2 year old were involved, then Chrysler finally responded. We are in the process of a buy back. They still want to charge me fees that I have agreed to pay just to get rid of this truck. As a dealer myself, my advice is to park your 6.7 at the nearest dealer, Chrysler LLC is and will risk your safety for profit, they employ a team of lawyerswho calculate profit and loss (us). They will not admit the danger to owners and the general public in fear of a massive law suit and possible indictment of senior management who play the “I was unaware” role. As consumers just stay away from all chrysler products, they will be obsolete soon anyways!!!!

I have an 07 3500 and it is the biggest pos I have ever bought. I have had the same problems as everyone else has said here. I just bought a 4in straight pipe kit with the fooler boxs. Fuck that emisions shit.
Comment by Shane — December 26, 2008 @ 4:28 pm
i have a 08 with 6,000 miles with no problems as to date but am looking for more info on the kits to remove the emissions stuff. DPF-R is the only kit i can find that deals with the sensor issue and was wonder if there are more out there. I am also a owner operator with big trucks to and can’t figure out why we can let the trucks sit at a high idle for 10 hours every night while we sleep in them with not very many problems,but with a dodge truck they are telling us to do all this stupid shit to keep the truck cleaned out. i treat my 08 the same way i did my 06 5.9 we live in a very cold climate so the truck simple has to be able to sit at a high idle to to warm up or to just keep its self warm in this cold climate – 30 in the mornings 0 degrees in the middle of the day. u just don’t shut them of, unless u like looking for trouble.
Comment by Daniel — December 31, 2008 @ 4:12 pm
I have the 07 6.7 and have had nuthing but problems with the exhaust. It was -56 yesterday and i do not shut the truck off. well we all no that is a problem because it plugs up and runs like shit.My fuel milage is at an average of 6.8mpg. if anyone has any ideas let me no. thanks North Pole man

we own a 2008 6.7 cummins and went through all the dpf problems and fixes. now it stalls, cuts out and feels like its running out of fuel while your driving it, no more check engine lights but they still can’t fix it and want to say its how we are driving it . we own a 2004 5.7 best truck we have ever had no problems at all the 6.7 needs some help…

2007 3500 6.7 diesel 23000 on it, has regenerated once at 11000. This is the best truck of the big 3 hands down.

I say when a person buys a new PU they should not be bothered or concerned how to drive so you kiss some computers ass! I miss my 2005 Quad 5.9. Never had a bit of trouble! I have had this 08 9 months and it has all kinds of check engine this and that. Going in for my new and improved turbo when it gets here in 30 days or so. My 08 6.7 check engine light came on the first week I had it. Maybe Obama has a fix for this also.

Where is this car lady with all the answers? I bought my 2008 6.7 10 months ago and am still afraid to venture far from home. But damn dogde has screwed me the last time.Oh, Dogde now tells me that a new and improved turbo is on order and will be here in 30 days.It will stop all the problems.BS! I will be going Lemon Law next.
Comment by Daryl Hauser — May 5, 2009 @ 2:07 am
I did have to blow a torbo & get the latest flash. Then I put a dpf-r kit in ,a air in take & run it till it starts to smoke blue real bad & sounds like the torbo is winding up when at idle . Then well the dumb fucken truck is doing this , when running go to the egr plug & unplug it . 1 more step , run it a bit , it will sound a little different then plug the egr back in & that will set it to the closed position & all your of problems disapear . With the acception of an engine light & that’s an easy fix to small piece of black tape .

I own a 07 6.7 liter. I have straight piped it with four inch to five inch to six inch stacks with the emmulater delete electronics. Check out purecummins.com for the delete kits. They are costly but so far worth it. I am fixing to get rid of my stacks to much noise which i like but to much vibration on the ceiling of cab..
Comment by Chalres Rab — May 24, 2009 @ 6:26 pm
For Dodge ppl they did not design the engine Cummins did and also for the exhaust problems read your owners manual you have to drive the truck for a certain amount of miles to clean the dpf out if you do alot of stop and go driving or live 5 miles from your work and do not use the truck for what it is designed to do then you are doing nothing to help the problem. If you do not like the dpf or egr then take it off and just dont whine when cummins or dodge say that your engine is not under warranty b/c you took the emissions equipment off.
Comment by Michael Obern — May 26, 2009 @ 7:53 am
I own a 07.5 2500 4×4 6.7 and found that if you tool around town the soot will build up fast. In town i drop down a gear so the rpm,s stay higher, this sucks for my fuel cost but it works to keep the dpf clean also it takes 5 minutes to clean the map sensor with brake clean at 5000 mile intervals. it sucks to this type of maintenance on a new truck but i own it for now no one will buy it i have had it for sale for 7 months
Comment by scott fitzgerald — June 3, 2009 @ 4:20 pm
Have an 07 3500 with 6.7. Had all the problems. working the truck does not help. I have had it since june 07 now has 200000 miles on most with 30ft. trailer pulling equipment. Got rid of dpf, cat, muffler, and egr. installed ram air kit and juice with attitude, truck now gets 20 mpg empty 13 loaded with no problems.
Comment by Ken Noble — June 8, 2009 @ 12:35 am
i bought my 2008 6.7 liter brand new and at 15,000 miles i took the exhaust off and straight piped it with a magnaflow muffler and bought the new smarty 6.7 programmer. About 1,500-2,000 miles later my dpf came on in my dash shut my engine power down to 50% i had to keep plugging my smarty in to delete my codes that would not stay deleted!! every 50 miles my engine would reduce power and codes would come on. i just said the hell with it and gave my smarty back and put my original exhaust back on and everything is fine now. my proffessional advice: DO NOT BUY A 6.7 LITER!! buy a 5.9, you can customize the hell out of it and its all good, but not the 6.7, hell no!
Comment by Michael — June 21, 2009 @ 11:27 am

I have a 2005 Dodge Cummins.
Several times a day while driving the truck will cut out for several seconds and when you push the acccelerator nothing happens. A few seconds later after tapping the accelerator it goes back to running normally. Somethimes it will just shut down altogether. I put the truck in Neutral and crank it back up and were off and running again.On other occasssions it will cut out, youy can press the accelerator and the engine will rev-up, but it will not gain speed!!!!!
I love the truck, but the Mechanic states that he cant find anything on the computer. It shows that the truck is in great condition.
Please help!!!!!

My 08 6.7L Ram 2500 with 15,000 miles on it crapped out on my for the second time today in less than a thousand miles. It’s sad that a $49,000 truck that I’ve owned less than a year has been towed to the dealer in less than a three week period of time. Are PowerStrokes and the Duramax having the same issues? Is anyone on this forum a diesel mechanic. Any input would be greatly appreciated.
Comment by Charlie Atwood — July 8, 2009 @ 6:01 pm
I purchased a new 2007 6.7 the last day of Aug 2007, the next day the check engine light went on as I was on a trip. I was in to the Dealers the next day. Within the week it was towed to the Dealers (fuel injectors) I had the truck in about 5 times for the ETC light(electronic throttle control) Towed into Dealer for second time the next month for injector again. Check engine light on again can’t tell you how many times. For the last 7 month no check engine light, after the last fix. Just had check engine light come on again and off July 6th 09. Dealer re-flashed it, may have to change out turbo next time. I feel for everyone here on all these problems. I heard Ford and Chevy will have the same issues when the time comes. Still have not enjoyed my truck and this is 2 years and 29k miles.

I have had lots of emission problems Iam on on my third tirbo sense dec 08, I would like to find a different turbo/exhaust brake combo other than than factory.Factory turbos only seem to last 3 to 4 months.I get good fuel mileage 20empty 15empty trailer 7 to 10 loaded trailer.I not empressed with how costly and high maintnance the 6.7 is.
Comment by scott conyers — July 10, 2009 @ 4:11 pm
we have a ‘07 6.7 and particulate trap always clogs, especially on long trips towing decent sized loads. Dealers have been replacing parts/sensors, thankfully under warranty, but problem persists. Have been reading everyone else’s troubles with these trucks, wish I had known before we bought this one last July. Will probably just modify exhaust to keep the truck running, will let you know what we did, cost, and most importantly, the results!
Comment by Derrick — July 16, 2009 @ 2:05 pm
I have a 2007.5 and runs perfect. Check engine is on due to DPF delete. I’m running a Smarty s67 tuner on 9, rollin coal, dpf delete, and K&N air charger. 21 highway, 15 pulling 10,000lbs. No problems. Runs as good as my ld 5.9. If you’re running a tuner and no dpf delete, your problem is there. The dpf clogs very fast, you all may want to research what problems you will have with your mods.

I have a 2007 6.7. Just now I’ve started having problems with my filter clogging up. You would think for the kind of money these trucks cost they could come with something better than this. IT SUCKS. I need to know where and what it takes to get around this filter shit and all it’s little censors. could some one give some ideas? Contact me at jandsgates@yahoo.com.

I have a 2007 Ram 3500 automatic 6.7 with 41,000 miles on it.
I am on my 3rd Turbo now.
Last week the ck engine light came on,but the truck was running ok.
I took it to my dealer to ck out and it ran fine on the way to them.
They called me up and said I has mass water in the fuel from my aux tank,and needed $16,000 in repairs and none of it was under warranty.
I said,Why hasnt the Water In Fuel light ever came on? He didnt know he said,I said why is it running ok,he said he didnt know.
I told them they were Nutz and I paid them a $99.00 ck out fee and pick up the truck.
The truck ran fine on my way back to work and the light was off.
I have since drained the fuel filter 4 times now after driving it another 250 miles with NO problems.
I have gotten very little water out of it.
I ran the truck completely out of fuel on purpose,drain the filter the last time got a few drops of water,put in some more ULSD and not Once has it run bad or has the light came back on since the dealer said it was full of water.
I’m hiring a lawyer Monday.
They told me once before I had the wrong air filter in it,had to call BS on them, it was from their parts department,they told not to use Fram filters,they told me my rear brakes were worn out and had after market pads on it,Wrong again,it was the front squeaking and they were the orginal pads and not worn out.

Has anyone had a problem with the ECM / PCM . I had one go out andChrystler is saying that the only way this could happen is if I had tried to put a chip in my truck. That is BS. tHEY ARE SAYING THAT IS THE ONLY WAY THE COMPUTER COULD HAVE BEEN WIPED CLEAN .BS BS BS .I have not done anything to this truck nor has anyone other than a dealer touched it.

I had a 6.7 2008 new ecm and pcm replaced. They don’t know why things are screwing up, I am on my 3rd. Turbo! EGR, DPF, Dodge SUCKS! They (Doged) needs to be sued before they go bankrupt!(it’s official) They have now parted ways with Chrysler. I hate Dodge!!!!!!!!!!! Their “Mechnics” don’t know what the problem is and it seems that when I pick up my truck from my multiple visits, all that has happened is they reset the check engine light, because you can bet money it will be back on soon!

I have a 2008 3500 with 6.7 and 6 speed auto. My problem happened at about 10.000 kil. When I am driving along and let off the gas to slow and then step on the gas lightly to come back up to speed, the truck will buck about 5-4 times before taking off. it will do it only when hot and anywhere from 50 kil -100kil. It does not do it when pulling my 36′ 5th wheel or at higher speed.Had it to the dealer twice (adj computer) but no difference. Can anybody give me sugestion as to what my problem is.
Thanks in advance

Blame the EPA not dodge. Dodge did not WANT to put this s*** on their trucks they were forced to. I own a 98 12 valve with the indestructable P pump. Depending on the tempature I burn up to 50% waste vegetable oil in her. Have gotten as good as 37 miles per gallon for the diesel I paid for. I have turned up the pump to where it will pull anything that a 6.7 will. Just keep an eye on the EGT if I am working her hard for a long time. I beat the s*** out of this truck and she just wants more of it. I hate to say it but I think 94-07 may go down in history as the glory days of Dodge/Cummins.

I trade my 96 5.9 with 432,598 mile in on a new 07 6.7 it was the biggest mistake ever it stays in the shop more than it gets driven dodge had an awesome thing and went and messed it up . buying a 6.7 is like haveing a kid you cant do this are do that. they need to get there shit fixed cause i know we are all tried of paying for it
Comment by Blacksmoke only — November 13, 2009 @ 9:40 am
I have a new 2009 6.7 with egr and dpf problems. I work the truck most of the time but still the dpf fills up — MPG go down, it starts hard when hot, and the dealer agrees but says Dodge does not have an answer. I have only 4k miles on the truck. What do I do.
Comment by Dennis Becktell — December 8, 2009 @ 5:00 pm
i bought a 08 6.7 in jan of 08 had to take it to the shop once about a month ago for the exhaust crap. so christmas day i ripped all the exhaust off from turbo back and replaced it with a five inch and added the smarty with the middle east download and its been running great lots of horse power
Comment by bolten — December 27, 2009 @ 7:01 pm
I traded my 05 2500 quad cab 5.9l for an 08 2500 6.7l.
Had my 05 in the shop more times then i care to talk about for a non working a/c that dodge said was normal. I had check engine light come on at 3k miles. Turbo clogging up, truck ran fine though. So they cleaned it, 2days later back again with same code. Had to get the new turbo upgrade. Been working fine ever since. but had another check light at 12k miles for o2 sensor…dodge said the exaust was running too cold, and needed to wrap the exaust…WTF too cold? I live in Va Beach, VA…but whatever…the code is gone and running strong with 30k on the odometer now.
but in strong rains, or big water puddles, water/fuel light comes on for no reason. dodge even changed the filter unit, and still had the damn light on for 4 more days. Light is off now, and truck runs great (at 14.4mpg avg if you consider that great… compared to 18mpg in my 05).

6.7l was being refered to in above starting with the turbo clogging at 3000 miles….sorry

Bought a used 2007 6-spd manual tranny with 6.7 Cummins. Clutch went out at 18,000 miles, various sensors went bad and check engine light on 4 different occasions. The DPF won’t regenerate past 70% and since I drive short distances, the engine is probably at risk. The truck now has 26,000 miles on it and I have heard that any mod that I make voids the warranty. Is this in fact true? I cannot disable the DPF that will ruin my engine without voiding the warranty?
Comment by stardot — January 16, 2010 @ 9:05 pm
i have had all these problems and more, i hired a lawyer and won $5300. i never had to go to court, and the phone calls and emails not too bad either, took about 8mo, only reason i did this was becouse the lawyer said i pay nothing if we dont win, so it worked out great, used the money to purchase H&S dpf delete kit, the best thing i ever done, it fixed all exhaust problems, everyone needs to do this so you dont have to spend your own money to fix your truck, so if your having these problems dont believe you have a shitty truck, cause you dont, dpf deletes avr about $1000. the 6.7 ltr cummins has more power than i could ever imagine and no more hesitation when taking off.

Listen folks, its not dodge trucks or cummins, the cummins engine is the best! the epa are the jerks! I am all about stopping pollution but give us something that works! I was in traffic because of an accident on 95 (east coast) for 2 hour, hardly moving and then “beep” the overhead display chimed and read “regen now 80% full! ok where? pull over and go to sleep for 2 hours and the run like hell down the highway to regen! Give me a break this engineered system stinks!! pull it back and re-think the whole thing.
Comment by chris soave — January 22, 2010 @ 9:04 pm
Stardot, I bought a new 08 quad 4×4, 6.7 and it was in the shop the next week, check engine. DPF is computer recorded. I am on my 3rd turbo,oxy sensor,egr sensor,heat sensor, on and on. It has been in the shop at least once a month since I bought it, 18 months ago. If you do tamper with the Diesel particulate filter, it will be recorded and show up on a diagnostic print out at Dodge, I said will be,and void the entire warranty for the whole truck. I will not buy a Dodge again. Dodge mechanics suck. I was also blamed for what they couldn’t find out. I have a work order that says all of the problems with my Dodge is driver caused because I was not driving the vehicle as it was intended. Oregon law states all new vehicle warranties have to have all operator errors, dos and don’ts written in the warranty. It does not say, driven a certain way.I had a perfectly good 05 Quad with the 5.9 diesel and never had a problem. I thought I needed a bigger motor to pull my boat, boy was that the worst mistake I made.

I have a 2008 6.7 Dodge. Check engine light comes and goes, but been on for 4 weeks now. I hope it blows. What are we to do with a bankrupted, now foreign owned manufacturer? Trade values are crap, they can’t even give the ’10’s away. Does anybody think they really want to solve the problem? Could sue, but what can I really expect. I’m putting on the dpf delete, egr delete, program upgrades, and say to hell with Dodge. If anyone else is doing this, find eliminator kits with “pressure boxes” so that the emission system bypassed, no codes are thrown, as normal operating parameters are sent to the computer. Smarty has the best programers too. Almost $2400 worth in parts, but a buddy did it, and gets 22 mpg w/3.73 gears.
Comment by Duke — January 27, 2010 @ 9:23 pm
I’ve owned my 2008 Dodge Ram with 6.7 since July 2008. During the 18 months I have owned this truck I have had 21 check engine lights. All of these due to exhaust. It has had three turbos replace, various sensors and multiple cleanings. They tell me I don’t work my truck hard enough. Let’s see, I run a power washing business and tow an 8,000 pound trailer 4-5 times a week loaded with a 300 gallon water tank and hot water machine plus everything else. I guess that is not hard enough. My check engine light is currently on again. Each time I take it in the dealer keeps my truck for 2-3 days. How much business have I lost due to down time with this truck? Since I bought the truck through my business, I do not apply for lemon law. Dodge has promised to fix my truck even past the warranty. Yeah! I get to turn my truck into the dealer atleast once a month for the life of the vehicle for 2-3 days plus the dealer is 45 miles away. I can not sell the truck simply because I can not morally stick somebody else with this lemon. I have no choice but to buy a dpf delete kit, I guess, and drive this truck “illegally”. Since we have no smog check in our area, I’m sure I will not have a problem. This truck sucks and shame on Dodge for not being honest with its customers. Each time I have brought in my truck the dealer promises me this is the final fix, Dodge has figured it out. Yeah right.

Another nightmare about the EGR/DPF, I have an 07 with the 6.7. I work in construction, we have a job we are doing on an remote site on a lake, this road is not plowed! while bringing in a thousand lbs of bldg material to the job site (I could on travel at walking speed in 4 wheel low 18 inches of snow) I got half way to the site when overhead display chimed and said regen now dpr 80% I still had 1 mile to go to get there!! when I arrived it went to 90% what the heck am I to do 2 miles back out how can I regen!!
Does anyone know who to complain too? I have this nice truck but can’t use it like a truck! If anyone has any suggestions please let me know..
Comment by chris soave — January 29, 2010 @ 9:09 am
I drove my 08 off the lot with 85 miles on it. The first few months were fine. In the last 6 months it has been in the shop 9 times for soot build-up. I have been told to drive it harder and always leave the exhaust brake on. With a lot of snow and ice in the area I live in, it is kinda scary to even consider driving with the exhaust brake on all the time! Drive it harder, don’t let it idle, drop it down two gears while driving at highway speeds! Dodge sucks! I am about ready to drive mine into the Missouri River and forget about it.
Comment by CJ Reeves — January 30, 2010 @ 8:03 pm
Chris, rip off the exhaust or buy a Ford or Chevy. My wife drive a school bus, and the “active regeneration” works perfect for them. These buses rarely run on highways, are always in stop and go traffic, and constantly stop and start the engines, but they have had very limited issues with the dpf filters. They don’t have any Cummins in their fleet. I was replacing the exhaust, but now I’m thinking of swallowing my losses and getting a Ford…
Comment by Duke — January 30, 2010 @ 9:00 pm
I’ve had my dodge 4500 for two years nows I love the truck! I havn’t had any trouble with the dpf yet. I pull a 32′ trailer most of the time, and I drive the hell out of it. I’m thinking about loosing the dpf. i do love the truck if only they would have put a 5.9 in the 4500’s!!!!
Comment by keith — February 15, 2010 @ 8:09 pm
Chris, You don’t want to buy a Ford or Chevy diesel. They have an injection cleaner that squirts a cleaning fluid when ever a soot buildup is detected. Works fine except,,,,,,,,,,,,,,,,,,,,,when the cleaning fluid runs out the buyer has to pay to have it filled back up. Sounds good?
Guess again. $1500 to refill! A light will come on when it detects soot clogs. Dealers say one charge is good for 60k miles; of coarse, how you drive or use your vehicle can vary this 60k miles. I am going back to gas. F150 mpg around 20 with the 5.4.
Comment by Daryl — February 17, 2010 @ 10:43 am
Recurring check engine lights, clogged DPF, Turbo…things to know.
1. Be very sure that your oil has not been overfilled. Too much oil in the crankcase causes the Crankcase filter to prematurely clog, which in turn, cause engine to build more soot. When changing the oil, remove the oil filler cap and allow the oil to drain (hot) for atleast 20 minutes and do not overfill.
2. Have dealership check crankcase sensor values (every oil change). A clogged crankcase filter has caused many, many egr, turbo or DPF problems. Book states to change the filter at 60,000 miles if it hasn’t already been changed. But most should be changed every 10k – 15 k miles.
3. Watch your fuel. Ultra Low Sulphur ONLY. period. make sure you are purchasing the fuel from a reputable station. Some of these privately owned Mom and Pop stores care very little about fuel quality.
4. Change your fuel filter, regularly. Every 3rd oil change. The truck circulates a full tank of fuel thru the filter and back every 20 – 30 minutes of run time.
5. All problems start up-stream in the system. If you have a clogged DPF, something upstream is to blame. EGR, Crankcase filter, fuel, oil (overfilled).
6. Change Technicians. If you are taking your truck to a Mechanic repeatedly for the same issues…..STOP!!! Find another service provider.
7. NO PROGRAMMERS. If you are running a tuner or programmer and your truck is under factor warranty, you are playing with fire. I have heard many success stories, but I have also written many a $11,000 – $16,000 repair estimates. The Injectors are anywhere from $380.00 (Aftermarket) to $1,100 (OEM) each!!! Currently during diagnosis they are running test that tell them whether or not you have had one “recently” installed. Programmers run a function that clears codes. If the service center sees that the codes have been recently reset, but you haven’t recently been in for service, they got you.
6. DPF Delete.. Installing a delete system does not, can not, void your warranty. No matter what anyone tells you. They can refuse to provide coverage for whatever component they believe failed due to what you have installed. If you install a DPF and/or programmer and your radio goes out (while you are covered) they cannot refuse to repair it. ITS NOT RELATED!!! Your warranty can not be VOIDED!!! It can be restricted (for review), but not voided.
hope it helps – ME

Hello, I have an 08 f350. I bought it new 0n dec 29 2008. It now has 45000 miles on it and not once have any trouble lights came on. There is no cleaning fluid to replace. In 2011 they all will have urea tanks added to the emmsions. Darrell

Darrell the urea tanks are being fazed in 2010 on. Cost for refill when depleted is $38. car lady put out that it was a $1500 bill to refill, wrong. The fluids are suppose to last till @ 60K miles. One more note car fax is a rip off!
Comment by Daryl — March 8, 2010 @ 11:17 am
how do i know if i put the wrong diesel in my tank i did not pay any mind tell now thanks mike
Comment by mike — April 13, 2010 @ 1:30 pm
Dear Mike,
It would be hard for you to FIND the *wrong* diesel fuel as most stations in town/city have only low sulfur on tap. Highway rest stops and trucker fueling sattions do have the *old* diesel but I would think oyu would not be fueling in the same lane as a “big truck”, without someone warning you away. Now gas in a diesel engine is another story, and the nozzle of the filler handle is typically too large for your truck, making it an efort to force the filler hose into the tank , not to mention the BRIGHT GREEN HANDLE.
Your truck will act up if it’s got gas in the engine, but diesel mixing could take longer to notice from the performance angle, the smell from the exhaust might be a more noticeable sign of something “burning”.
any comments… please feel free…. SLM
Comment by mycarlady — April 13, 2010 @ 9:30 pm
This is ludicrous. So what is worst hauling @$$ to go into regen mode but happen to get a ticket? getting into inevitable half a days worth of traffic on a road trip and then having to be towed to a dealer to have them clear it out for you? running your diesel to 1400 F EGT which i have yet to find any diesel to live a long life at? or just finding a dealership that will look the other way and let you take off all the junk and still get a warranty? hmmmmm

I just bought a 2008 Leased Repo 2500 quad Cab with the 6.7 diesel. I am a Cummins mechanic for Dodge for 25 years on the line. Man guys I feel for you all for the mechanics out there today are idiots. As well as Dodge, they have NO IDEA what the problems are nor how to fix them. I took my truck in for the newest recall which I had to find on the internet myself. It took them 6 hours to do a 1 hour job, then was told they could NOT TEST DRIVE IT FOR THEY WERE TO BUSY!!! MAN WHAT A CROCK!! When I was on the line we test drove ALL even if it was just to replace the wiper blades. It seams the auto dealers are just there for the money and to heck with the customer.

Well, just installed the DPF-R (DK-30) on my 08 2500. Man what a difference! If you haven’t done this yet, you are missing out. Mileage is at 15 city and 19/20 highway with a ton more power, no stuttering and no CEL’s. Even sounds like a real truck. I have been running it for 2k miles now with no issues at all. Next will be an S&B intake system.

Got an 09′ 6.7 with 20,000mi on it and only one bad o2 sensor at 13,500mi. Trucks been put on full restriction for my installation of an MBRP, DPF back exhaust system. The local dealer here in Casper, WY claims the aftermarket system melted one of the rear shocks???WTF. The dealerships general manager said even a tip on the stock exhaust would void my warranty…HUH, are you FU***** stupid? Why the fu** is the entire truck on restriction, Guess they don’t believe in faulty components off the line?? Or maybe they just don’t like someone telling them they have a shitty product?? This was my first dodge and probably my last, dealer service sucks ass!

Have had my 2008 19 months now and have had ten CELs. The DPF was replaced last winter at 16K along with the EGR. Just had the EGR cleaned and CEL came on after 78 miles. CEL is still on, truck seems to run OK even tho the milage sucks. Will go to different dealer on the 4th as the last code had no info on at local dealer. I run the brake on and drive the crap out of it, no idling/bogging etc. Should have kept my 2005 5.9
Comment by charles weidman — July 29, 2010 @ 8:57 am
I bought an 07 new with zero miles at the dealership, and didn’t start to have problems until about 15,000 miles, the engine light came on, dealer cleared, so i made an emergency parts trip to California for my construction business and light came on again on the coast, dealer said run it, so I ran about 120+ coming back to Phoenix, light cleared. About a month later, light came on on the way to a service call and dealer had to replace turbo and cat. They have done all the latest flashes, upgraded the regen programing, whatever. I was scouting for my deer hunt and got stuck down by Tucson, had to tow to dealership there; on my third turbo and cat clean. Arizona lemon law best in U.S. but I think I’ll try for a lifetime warranty, only 20,000 left on my 100,000, best truck I have ever owned, drive it like I stole it, but the emissions issues are crazy. Told dealer it’s a shame and a lawsuit that Dodge has been using the public to finish “testing” this rush to market crap, and I told them I will Never in the future pay for anything on the drivetrain, that it will be warranty until hell freezes over (deer in the headlights stare, ha ha) The dealerships know we have them, based on the performance records nationwide alone, so a class action suit for lifetime warranty, or 5.9 replacement of the 6.7? How ’bout we just get Congress to waive emissions on diesel so we can run ‘em like every other country in the world does?
Comment by terry treadway — August 3, 2010 @ 8:21 pm
Got the latest flash for the regen back in May for my ‘08 3500 6.7. 2 days later ran like crap. 2 days after that DPF won’t regenerate. Hmmmmm? It had 115,000 miles on it so I got to pay $2500. 2 days after that still ran like crap. This time it’s the tranny. Got to pay $3500 for that. Still ran like crap and then the regen message came on but it wouldn’t regenerate. Another DPF but on their dime. Still ran like crap so they said the trans control module was bad. Changed it and still junk. Then they put a whole new transmission in. Junk again. A new ECM was supposed to do the trick but it’s back in the shop. Now they think it’s the EGR or EGR cooler. I’m not up on this new system but I ran the thing hard, towing every day for 115,000 miles in just over 2 years. It ran like a champ. The second I get the latest flash it’s junk. The dealership is closing in on $20,000 in work on this deal and Chrysler maintains there is no issue with the new flash. It has to do with the DPF and EGR and that is where my issues are. The dealer says I’m the only one with these issues. Let’s all call Chrysler and have them fix this!
Comment by Chris Houtchens — August 4, 2010 @ 8:42 pm
Everyone seems to be talking trash on the 6.7 ltr Cummins. As a professional mechanic I can tell you when it comes to modifying a vehicle the farther you get from stock the more trouble you will have with it. I have seen it all my career. I have a 2008 Dodge d 3500 dually w/14k miles on it. Never had a lick of trouble with it – never went into regen or ever quit me. I run it hard to work and back when light and tow hard with it the rest of the time. My only complaint is the mileage could be better, but anytime the feds get involved with something, they will f__k it up. This also includes emissions standards. In order to clean them up it requires extra fuel. I love my Cummins, it runs clean, had tons of power and has been super dependable so far. Definately worth my $48,000.00.
Comment by John Holland — August 13, 2010 @ 8:16 am
I have an 08 6.7 2500 and have been having the same problems that are stated above. The only way I’ve foud around these issues, NOT going to the dealership, is my programmer. I own a SuperChips Programmer. This unit has a built in “DeSoot Mode”. As you drive he truck, you can tell when the DPF is really starting to clog. The black smoke pouring out the back, the turbo will not spring up…etc. Plug the programmer in and set it up for “Mobile DeSoot Mode”. Leave the programmer plugged in as you drive the truck at interstate speeds. You can watch what happens during the “DeSoot” process. The EGT reaches above 1100 deg F and the Delta P across the DPF chamber is high. Usually somewhere in the 6.5 inHg area. This is what turns the check engine light on. The truck should be running at somewhere in the area of .250 to .450 inHg (inches of water column) This is much less than 1 PSI. So it does not take a lot of back pressure to really screw this system up. So once every 2 weeks I take the truck up on the interstate and “DeSoot” it. After I’m done with the process…I get about 22 MPG on the interstate and 18 MPG in town. Yes it is a pain to have to do this. I keep the truck programed on Performance and it runs great. No other issues. This programmer will also clear codes and let you read the codes.
If I didn’t have this programmer…I would be at the dealership at least 3 times a month for this DPF issue.
This my small win the the DPF battle.
Comment by Robert Lucas — August 30, 2010 @ 6:32 am
Most of the 6.7L problems that are happening now are from incompetent mechanics and the people that drive the trucks. Maintenance is the key to providing a long and healthy diesel particulate filter. On all 2007 and 2008 trucks when they were first introduced to the public they were not programmed correctly for the way the trucks would be used. After the engineers have gone from ECM software with part numbers ending with the AB suffix all the way now to BE the software problems seem to be fixed. For all of you who had trouble within the first 30k or so the software was mainly the issue. Now that the software has been fixed most of you will find that if you have not been changing your filters properly, which has become an as required as opposed to a mileage time frame, and those of you who have been over filling your engine with oil are the ones having the most problems now. These truck are very sensitive to having poor fuel in them also. I work on these trucks every day and have talked with every engineer I could and there seems to be no one end all answer to the problems with these trucks. My advice would be as follows: 1) Make sure you have good clean air and fuel filters at all times. (Warning: The 5.9 air filter fits in the air filter housing but does NOT flow near enough air to accomodate the 6.7L engine. Do NOT use it!) 2) When you have your oil changed let the vehicle sit in the parking lot of the lube center/dealer or where ever it has been changed for a minimum of 15 minutes then go out and check the oil level yourself. If the oil level is above the “SAFE” zone on the dip stick the vehicle is over filled with oil and the excess MUST be drained. Excess oil is the number one cause of the DPF clogging up. 3) Reduce your idle time. Idling the vehicle causes excessive soot build-up and besides all your doing is wasting fuel. 4) Make sure you are using high quality Ultra Low Sulfur Diesel. Water in this fuel system can cause the injectors to rust and clog up. This can lead to a no start or can lead to excessive fueling by the injectors becoming stuck open which will cause excessive soot and your DPF to clog up faster than it can be cleaned. 5) Take your truck in to the dealer and have them check the ECM to make sure it has the latest flash file. Recall J35 is in effect and if you have not had it done yet and the recall applies to your VIN then the flash will be done at no cost. Also it will be free if you are still under the Diesel Engine Warranty. This flash will correct many problems associated with software issues that cause excessive soot build-up and turbo issues. Alos there is a new design turbo that will be installed if you do need a trubo replacement. If you receive a new turbo it will have a cleaning port installed just above the oil line that goes in to the turbo. If your new turbo does not have this port you gave received an old part number turbo and you will end up replacing it again. Ask for this turbo to be removed and the correct updated part to be installed. 6) Every 67,500 miles have your crank case filter replaced and the entire EGR system cleaned. You can do the cleaning yourself using the EGR cleaner available at your local dealership or you can have your dealer do it. Also if you discover that your lube center has been over filling your crank case of you have had several dirty air filters then changing your crank case filter is advised as soon as possible due to the increased oil accumulation in the filter caused by a dirty air filter or excess oil in the crank case. 7) Make sure your dealership is using a qualified Level 4 diesel technician when you take your vehicle in to have it worked on. If your dealership does not have one go to another one. These are the only employees at a dealership that have the authority to work on the 6.7L Cummins engine. There are several people who have had the 6.7L Cummins engine and have had a very enjoyable experience with their trucks by following these guidlines. Do these vehicles have some problems? Well of course they do. But if you dont take care of the truck the truck wont take care of you. Sadly gone are the days when you could neglect and abuse a diesel truck. The 6.7L isn’t your dads diesel.

Incompetent mechanics and people who drive the trucks? I am responding to this because your remark is an insult to the thousands of loyal Dodge owners who purchased their Cummins 6.7L with no previous knowledge of the changes made to the engine, no instruction from their sales person (warning them of the poor fuel economy and constant warranty issues) and the host of Chrysler certified technicians who have beaten their brains out trying to service the customer.
All the flashes, fixes and replacements made have not “resolved” the problems for most and coming over the 100k mile mark has left many owners stranded, with the dealers and Chrysler charging them for fixes that never are. Interesting that the new 2010 has a new idle control unit that magically has “fixed” the soot-regen-chk engine light issue, but this part can not be retrofitted to the old trucks, and Chrysler isn’t warranting the 2007-2009’s for life under goodwill. No, I think the term incompetent is misdirected, as the designers of the first 6.7l Cummins REGEN system own that moniker.

Mycarlady, in my post I did not mean to offend anyone and if I did I do apologize. I happen to be a Level 4 Chrysler certified diesel mechanic who works on these trucks all day long and my own personal experience has shown that 90% of the trucks with the 6.7L engines that have come in with a check engine light and a DPF with excessive soot after having the latest flash files installed in their ECM have been having problems because the customer has not been educated on these trucks and the requirements that are needed to keep them healthy. I only got on here to hopefully try and educate some folks to why SOME of them may be having problems. I can just about guarantee that if many of the readers were to go out right now and check their oil levels they would find that their engines have been overfilled on oil. I am the only certified technician at my dealership and I am losing my ass working on these things. We do actually good will quite a few vehicles. The test and diagnostic sheets that I have to fill out on each and every one of these trucks really eats in to my day. I just wanted to get on here and give a few tips on things that people can do to decrease their trips to the dealer for repairs related to their DPF and turbocharger. At my dealership we have made pamphlets at our own expense to give to customers to try and help them understand how their truck works and the steps to help avoid future occurences of problems associated with excessive soot build-up. I too am outraged at the way the salesman have shoved loyal Dodge customers in to these trucks without going over their maintenance schedules and how the de soot process actually works. It is my opinion that many of these problems could have been avoided if the selling dealership had taken the time to go over how the system works. In no way am I trying to insult my customers but like I said in my own experience I have found that many problems can be avoided by doing proper maintenance. If you really want to be mad at some one be mad at the engineers who did not correctly field test these trucks before putting them on the market. When the first 6.7L trucks arrived at my dealership as soon as they rolled off the transports we had each one in the shop installing new software. Yes, this has been an on going issue and yes some people who have not had their up dates done will have problems. But I have seen many of these trucks with problems come in and get the latest flash files and I never see them again except for their regularly scheduled maintenance. The rest that end up coming back I almost always find something that the customer or where they have been having their maintenance done such as their local speedy lube have actually caused the problems. Sorry if I pissed anyone off. I ask your readers who own a 6.7L Cummins let your truck sit for 15-20 minutes go out and check your oil and report back what you find on here. I am willing to bet the farm that several of you have trucks that have been over filled.
P.S. When I say incompetent mechanics I am talking about the guys who, unfortunately, have not been trained and do not have the knowledge on these systems to determine the correct diagnosis of your vehicle. Think about it. If the guy working on your truck has no clue why your DPF has sooted up and just throws another one on then of course you’re going to be coming back in the future with the same issue.

Yes Sara, this is a 4WD Megacab. Mileage hauling a 7000# camper and 70 to 80 miles per hour is a round 10 to 11 mpg. You have to set the truck up in tow mode. The performance mode is alot more power and you can tell the difference but the DPF does not like it one bit. I have every-now and then gotten 25 mpg out of the truck. But not very often. The planets really have to line up for that to happen. If I don’t “Desoot” the truck every 2 weeks the mileage falls off to 15 mpg period W/O trailer.

HI Tony,
Thank you for the follow-up response and explanation. I am going to recap some of your suggestions into a formal blogpost so everyone reading this blog gets the benefits of your suggestions. If you would like me to name you and your dealership, I will be glad to do so, as you have done a solid job representing them here. I believe the readers of this post reserve fair and responsible information and support at all levels of the Dodge 6.7 issue and anything that will help is great.

Tony…I must agree with Sarah here. This is some really good information, I don’t care how you delivery it. Just as you said, I was not informed on anything about this truck. “Just get in it and drive it”, per Mark Dodge.
The issues that you have addressed in you replies opens up a few doors that really need to be looked at from an owners stand point. My DPF has been acting up for 25,000 miles. Dealer tells me “tuff”. 2100.00 to replace it. My little programmer keeps the truck going just fine for now. I just have to keep it on a “DeSoot” schedule. Is there a shop manual out for these trucks yet?….Do you know. Thanks
Sarah, I would like to know when this “blogpost” might come out so I can keep up with this issue. Thanks.
