Does anyone know how frequently regen has to occur to get a P2549 code? since picking up my truck from the dealer on friday, the following has happened:
- Picked up at 68490 miles
- DPF guage was over ¼ full by 68534 miles
- Regen started at 68581 miles (delta 91 miles since picking it up)
- Regen ended around 68620 miles and DPF guage instantly showed 1 notch up from empty
- 68690 miles – another regen started (delta 70 miles from end of last regen
Seems like this would be frequently enough to cause a "frequent regen" code but nothing pops up on the dash. Is this a "behind the scenes" code? I have a case open with ramcares but the dealer wants it to give a code before they are willing to do anything.
I also checked MAP and MAF sensors right after picking up the truck. The MAP sensor was very dirty. I cleaned it but that obviously doesn't seem to have done anything.
