I went through the same issues with my 3500. They kept throwing parts at, EGR valve, sensors even a turbo. Nothing helped until they changed the DPF filter itself. That was at 18000 at 24000 now with no issues so far. Regens around 200 miles around town, Filter shows 0% When pulling camper. Went...

I think I've pretty much found the extent of the knowledge at this dealership. If...when it trips CEL again I'm going to try another dealership.

Went back, tech says MAF shouldnt have been on repair order because he decided he didnt need it after all. Blamed it all on low def. Just reset CEL and drove it. I asked him to show me in the manual where letting it get to a 1/4 tank was unacceptable. We havent found that page yet. Then he went...

This is the third time its been in the shop for frequent regen. First time they said it was the wrong air filter, second time they said it was the delta psi sensor now we are at the turbo issues.

According to the tech the seals are gone in the turbo pushing oil into the exhaust.

Thank you

Chris, What info would you need and is there a link for PM?

It is under warranty than goodness. The tech tells me he has seen this alot in trucks that were initially delivered w/o PM sensors. Didnt know if anyone else had encountered similar issues.

Ive read a number of threads on regen issues. My 2022 3500 is in the shop for the 3rd time in 15k miles. Diagnosed 1st w/ wrong air filter, 2nd w/bad delta psi sensor, now they say turbo is bad blowing oil into exhaust clogging dpf. Anybody been down this road that can tell me what I may have to...
