Would not disagree, but I can't figure it out. And the dealership has no incentive to do anything more then what their failure mode tells them to do. They plug it in and it tells them the DPF is full so they do a manual regen, and plug it in again. If it still shows the DPF full they replace the ceramic filter and call it a day. Dodge doesn't pay them to do anything more. I have thought about putting the factory air intake back on to see if that fixes the issue, but I had it on the first time they replaced the filter. I have to say it took longer the first time though?

Air filter wont change anything unless the filter was plugged up

Sorry to tag onto this but it looks like a conversation associated to my problem?
So, regarding the thread and the DPF and dealers, I just had the actuator replaced by the dealer (extended factory warranty). After they installed it they called and said the DPF is full and will not regen they want 5K to replace the filter. I picked it up today and drove until the regen complete notice appeared. Can the malfunctioning actuator and limp mode cause the filter to fill up?

Absolutely that is likely the issue, the dealer likely tried a manual regen and it failed instead of trying to drive it

Hum. I just watched a video on the boost leak test you mentioned. After I get the Truck back I am definately putting the factory air intake back on and checking for leaks. Thanks

No need to put the factory air intake back on they are not an issue despite what the forums think

The issue may have been a CP4 related problem time will tell

yes... the DPF getting full is just a symptom, not the problem. Continuing the just replace DPF after DPF is foolish.

Yea most of the time its EGR valve is sticking open a little and letting in way too much soot. I would fully pull the EGR system, cooler and all, then preform the service on it to clean it all out and inspect. I think they stopped requiring newer trucks to do the service. On older trucks it was the 67,500 miles service. But it would still apply.


at minimum pull off the EGR valve and inspect. A bath in purple power wont hurt. its super easy and the most common suspect.


I do admit I dont know much about the changes in the newer trucks, so someone correct me if I'm flat out wrong here.

You cant pull the EGR valve apart to clean them on these trucks either they work or they dont also even at 250k most people have almost no buildup in the EGR system due to how little EGR they use. I would be willing to wager it was a fueling issue due to the CP4 that little ******* caused so many issues

The 2014+ trucks use a lot less EGR than the previous years (07-13 pre DEF)

Yes i did say they use very little EGR… also DEF started in 13 not 14
