DPF / Extended Contract Issue

[BruteForce]

Harvey: Yes, but I found that initially my dealer chose to "ignore" the EGR code and focus on cleaning the DPF and Turbo. They'd clear codes, then I'd be back in ~300 miles. Finally, I forced them to resolve the EGR issue. Problem went away.



Edited to add: That was back when you could pull your own codes using the key trick. Dodge in its wisdom has disabled that function on our trucks. Now you need a OBDII scanner or a tuner.

Sometimes and with some dealers having some knowledge of our trucks and the cojones to go to the dealer and push back can make the difference between being a happy owner and hating the truck.

We haven't heard from the op of this thread in over a month. I wonder what has happened? His future with the truck he bought doesn't sound great.

I'd like to know whats up with his truck also. I just bought a 2010 and couldn't care less if the DPF/EGR start giving fits. I'll drop them all like a bad habit. Other than the first year of the 6. 7 it's been a great engine here in Alaska. Even with the cold if you get out and run the heck out them they seem to be doing ok as long as they get worked a little.

Ok,,, Well I know there are still a lot of dealerships that don't know what to do when they dpf 70% full light comes on. The proper procedure is to take it up on the highway and drive it in 5th gear at about 65 or 70,,,,high rpms, untill it tells you the dpf is OK. This is a way to force regen. I agree that they can't adjust regen, so they just go rid of you.
If after forcing regen, it still says the dpf is full. Try having them replace the crank case filter, or the crankcase filter sensor. Yes, it will throw a code for DPF full, and the overhead will tell you the DPF is full, if the crankcase filter is full, or the CCV sensor is bad.
So just go try that and see if it helps.
Don't get mad at the truck. It is a great truck, especially if you delete it. But they do some weird things and once you learn that, you will be OK.
Just go do the force regen up on the highway and see if that helps. Then let us know. Please.

The Magnuson Moss Warranty act works - and is not limited to first purchasers. If your state lemon law has a mileage limit you might want to check this option. My 6. 7 was lemoned at 25000 miles after nothing but chronic DPF plugging. You can read some of the details here:

Sorry for not posting sooner a follow up. Here is the full update...

About two weeks after the original post everything was worked out with the Newberg Dodge dealer. They requested the technician work sheets from Salem. Seems that Salem did not follow the troubleshooting flow set by Dodge for this issue. Two different technicians worked on the truck and did not compare notes. A turbo and two DPF filters were replace under their troubleshooting in less than 4,000 miles. Issue was not resolved.

Fast forward to my ownership:
Newberg went back over the prior work and found that the DPF filter housing was never cleaned along with the filter replacement. The housing was caked in carbon. They proceeded to dissemble the system and clean all the carbon. The EGR was completely carbon over. Newberg replaced the EGR and also modified the EGR by drilling out to be a bit larger. The service manager claimed "it reduced trucks from coming back on this issue".

I was glad I had the extended warranty cause it covered the costs 100%. Since the work the truck ran great.

Also of note I researched the Oregon lemon laws while allt his was going. In short lemon laws only cover "new" vehicles, and even then there are set criteria to be considered a lemon. Which left me out entirely.


Present Day:
My check engine light came on again over the weekend. In both occurrences I was driving without a load and extended interstate driving. I'm taking the truck in tomorrow to see what the new issue is. I'm hoping just a time to change the oil indication.

If it was the oil change, on the overhead, it says oil change required. . the check engine light don't come on

Drilling out egr..... sounds like somebody is getting smoke blown somewhere

Drilling out egr..... sounds like somebody is getting smoke blown somewhere

That answered my question before I even had to ask it.

So the dodge dealer informed me today that the new code on the truck is a P2002. I received more lip service and that we will have the truck for at least a week and half to troubleshoot and fix. The seems a bit extreme to me even with only 1 diesel tech on staff.

Once again the work is covered by the extended warranty, however frustration is beginning to set in. I asked about a DPF/EGR delete to eliminate these check engine issues, and would have thought I drank this service managers last beer and kicked his dog on the way out the door. So i spoke to a guy at Source Automotive here in Portland about a delete kit. Turns out that since January 1 the EPA has laid down the law it is illegal for shops like his to remove emission systems and install delete kits. Only vehicle owners can perform that type of work.

What a bunch of BS. So how do you fix your truck? I have a feeling this wont be the last time the truck has a check engine light for this issue. Has Dodge acknowledged the issue and formulated a "fix"?

 

[GCP]

There's a reason why shops won't do the work. It's illegal. Like it or not the emissions gear is required by law.

Do you have another dealership you can work with? If the one your using now didn't fix the problem originally, what makes them capable now?

Don't lose hope. A good service department should get you back up and running painlessly.

Chrysler/Cummins developed a couple of reflashes for your truck which was effective on most trucks. A replacement turbo with a clean out port was also installed when turbos were replaced under warranty. I'm not aware of any other OEM modifications but not certain there were none.

What is your normal drive cycle? Is the truck being used in enough highway speed driving or towing to allow the regen system to keep soot level down?

 

[stick218]

I asked the service manager and he told me all the recalls and flashes are up to date on the truck as of late last year. We might drive the truck once a week in town for about 40 to 50 miles. Freeway driving is one to two times a month for another 40 to 50 miles. Right now it is the off season for camping and towing, so not a lot of activity with the truck. Once the weather warms up some we have a 5,000lbs travel trailer we tow for camping and we have four quads to tow around as well.

Stick,

You can obtain a carfax report yourself online for less than $30. I recommend you obtain one to learn the history of your truck.

Normally all franchised dealers report service performed and it will show up on a carfax report. So would anything like a Lemon Law buyback, a transfer of ownership or significant damage resulting in an insurance claim.

A carfax report will either show you the truck is a lemon with a long history of problems or, more likely, just an early 6. 7 subjected to a light duty driving cycle now experiencing some soot issues. If you recently bought it it could have been a daily grocery getter before it was traded and will take you some time and service department visits to get it cleaned up. Once cleaned up your duty cycle should prevent further issues.

The trucks that have had the reflashes performed (correctly) and used for highway driving and towing are working fine.

I have a 2008 that had to have the DPF replaced at 60,000 miles. Since they did the work, my mpg has decreased from 15-16 mpg to like 12. Anyone else had this happen?

 

[jgillott]

Did they do any programming changes or replace anyting other than the DPF?

 

[JCJohnson]

Do they have a "lemon law" and would it apply? I love my truck but your issue would drive me crazy.

 

[stick218]

12MPG doesn't sound right. I got really poor mileage when I had my error code. I'm not sure if it was because something was plugged or the truck running in regen mode.

I have since got everything running again. It took the dealership another DPF filter, new EGR, and lots of carbon cleaning in between. Right now everything is running fine, so where they did seemed to have worked.

from my research "lemon laws" only apply to new vehicles not used. Then each state has different criteria to meet said law. .

Now I have console lights to replace, but that is another thread. .

 

[HBarlow]

Stick,

I noticed in a previous post some time ago you mentioned a two piece DPF with a shell to be cleaned and a filter insert. I didn't comment on it then, thought it might be a misstatement. I think you are misunderstanding what the dealer is telling you or they are giving you incorrect information. The DPF on our trucks is not a shell with a separate replaceable filter. I think Class 8 OTR trucks use a cleanable DPF but our trucks have a sealed unit that has to be replaced if and when it fills with soot.

I wonder if the dealer actually replaced the DPF during your earlier problem?

GEEEE I want a new truck so I can have all the problems, Another example of our Government RAMING CRAP RULES up our A** without having the technologies down TO MAKE SURE IT WORKS FIRST
