6.7L Cummins Forum

well 18 days in and still no definate answers. frustration is overwhelming me, and apparently there isnt squat i can do about it.

OK READ EVERYTHING, and was captivated, please let me know what happen, how did it all turn out?

I went through the same thing. I called lawyer, threatened to sue Dodge/Chrysler and they ponied up sufficent amount to pay for DPF delete and Edge Juice with attitude. Truck runs fine now, with about 24.5 mph the norm at highway speeds. Truck hauled from dealer on wrecker, after market equipment installed the same day and by 5:00 pm, I was driving down the highway without a problem. God bless Texas.

I agree with Hillge and have gone in that direction. I dont have a lot of faith in the dealers around here and thats one of the reasons I went the dpf delete/programmer route. Taking the time to drop off your vehicle, arrange a ride home and back when they claim its been repaired is a pain and many times the problem returns. A warranty is nice as long as you dont mind spending your time driving back and forth to a dealer and being days sometimes weeks without your ride. All 3 brands with emissions equipment have issues so dont feel like its just dodge/cummins.

I have to rant and little and have to point out something here with the junk comment ..... The 2007.5, 2008, 2009, and 2010 model vehicle are all exactly the same when it comes to the engine and exhaust system. The only difference is the ECU code.

Yes, very early on there are a ton of problems of DPF's plugging up and things getting all gummed up. However not all of it was the vendor fault, dpf and egr for diesel is a new thing and requires a learning curve. There should have been a training program at the dealers before you purchased these new trucks and before you drove off the lot.

With the fixes in the ECU code, things have gotten much more stable and people are learning how to handle these new setups. Some of you are old enough to remember the same thing happened with air pump, egr, pvc, and catalyst with gas engines back in the 60's and 70's ....... Now a days, we do not even think twice about this stuff on a gas engine.

One major fault is the lack of good experienced diesel mechanics at the various dealers. They want to sell and believe anyone can service, WRONG! In some cases, minor problems are being made into major disaster because lack of experience.

So please do not call a specific year junk due a programming problem and/or lack of dealer expertise. Many of the factory buy backs when corrected run like a champ with no issues. Software updating and patching is not something a caveman can do, its at times is an art form. This is something I constantly have to beat into my team and constantly have to train on (I can talk volumes on this alone). Yes there is an occasional unlucky #13, but that is true for anything.

Side note, one thing I do not understand with dealers and Corporate HQ is that there is a known problem upgrading some of the original ECU's, once done, the code just has issues. The time is takes to remove the existing ECU and replace it with a new one and reinstall the VIN is a lot less and far cheaper and consistent reproducible results. The original ECU can be returned for re-initialization and reload the correct way and reused for rotation. But no, they have to do things the hard way and make things worst at times.

Now if you have a truck and its spending more time in the shop than the road due to idiots and you can solve the problem with a delete, I do not blame you one bit (I would do the same). But we have to face facts, smog control for diesel is here to stay and like gas engines, will eventually be adopted by all states.

Yes, the other vendors are having problems also. Some of them much more major then ours and much harder to deal with due to the designs and no deletes possible.

Ok, rant over

I really wish bkdraftbn1 would post an update, would really like to find out what happened. It amazes me how many times I see people with problems and the truck disabled, as soon as the delete is done, the truck comes back to life. Its like having bypass surgery

WELL SAID!! The trick is to find a small town (rural) dealer whose inventory is high in trucks and the truck line is their major sales source. Make sure that they have a good cross section of customers (farmers, hot shot drivers, tow trucks, Heavy pullers, RV pullers and daily drivers, etc.). If they are in this situation they will understand the necessities of the different users and service the truck accordingly.
My dealer is very heavy on the truck end. The service manager and mechanics all understand that some of their trucks run better and do a better job with out the DPF etc. They do NOT arbitrarily deny warranty for mods, in fact they sell and install many mods and accessories.
My truck is an '07 that I purchased new in January of '08. When I picked it up every software update had been installed along with a set of rear brake caliper shields and high idle enabled. Before handing me the keys, the salesman spent an hour+ with me going over the truck's features, how to operate them and how to maintain them. The truck is coming up to its 3rd birthday and has been virtually flawless. I have had it back to the dealer only 3X in 110,000 KMs. for a reflash, for the firewall recall, and the last time for the J35, to turn on my fog lights with high beams and set the speedo for my 285 tires. All done, no questions asked. If they need the truck for more than an hour or so they present me with the keys to a loaner vehicle. Over the years, these guys have become friends and they are a pleasure to deal with and recommend.
The truck is stock except for a gutted intake tube, a 4" hole in the bottom of the intake box and an unplugged EGR.

You have one heck of a dealership up there. The way things are handled by Dodge and other manufacturers leaves a lot to be desired. I understand peoples frustrations when things go wrong and the dealer tells you that""you didnt drive it hard enough, you idle too long or that cai flows too much air" is just not an acceptable answer in my book. Our trucks are very expensive and shouldnt have alot of these issues and I realize all of us at some point will get a cel but I want to limit my trips to the dealer. Mods and deletes are not for everyone but are a great option. I know alot of us tell other dodge owners to delete and install a programmer when they start having problems but its worked for alot of people and more than likely will fix their problem. Theres nothing wrong with keeping it stock or throwing some mods at it. I modify every thing I own because I think the factory could have done better and I will continue to do so at my own risk. One thing we all have in common is we all own an awesome truck with the worlds greatest diesel engine in it.

i know this is a few months old, but wanted to chime in. i have aa 07.5 i bought used in jan of 08. original sale date was sep 07 and it had about 10000 miles on it. it is my first diesel, so shortly after buying it i started researching. i found a lot of complaints about the 6.7. this got me worried so, more research. i am now at around 80000 miles and have only had 1 cel come on. it was about 35000 miles. the light actually went off before my appointment at the dealer. they had it a couple days , did a recall and a few other things. i was thinking here we go. i have had no problems since, and plan of having this truck for a long time. i rarely go more than 300 miles before a long highway run and pull a fifth wheel regularly. i guess that does the trick. by the way, i am new to this site and have already found a lot of useful information. thanks

We have seen numerous occasions where the J35 flash did not properly store. This coupled with the intake is probably the source problem for the other issues that you are dealing with. In other words the EGR and turbo vane travel are probably due to soot build up caused by the J35 and intake combo.

Prior to the J35 aftermarket intakes and air filters were altering the delta point at which the vehicle would go into regen, pretty much making it a certainty that desoot would not happen. J35 essential removed this parameter from the process. Rather than waiting until necessary to regen and giving the customer the remote chance of decent fuel economy J35 forces regen on a very frequent basis, and under many more operating parameters.

I would suggest that the shop again load the J35 update, leave your intake out of the list of questionable items, clean the turbo, and the entire EGR system including sensors. They should also pay particular attention to make sure you have all of the latest updated components including fuel filter and housing, EGR valve, and sensors. This should solve your problem for good, but only if you stay on top of air filter cleaning, and fuel filter replacements.

As a note the noise that you heard and the puff of smoke indicated a catastrophic failure of the DPF very likely caused by the above listed components. What you heard was a hole blowing through the DPF filter media.

Bring it to Denver we'll fix it!

You wouldn't want to give a short write-up would you? Because I'm always looking for more info on the subject as you can tell from my posts. LOL
