I've got a 2015 3.2l diesel I bought about a year ago. Just before I bought it the previous owner had a bunch of emissions work done so it was sellable in CA -- DEF tank heater, sensors, etc.
I got it with ~105k mi on it and it now has 115k mi. I recently moved to a new place <1mi from work, so I assume this problem is due to short drive cycles, but I'm really not sure.
My code reader is showing multiple P0420 codes (though I think it might just be storing them) and I get a constant "drive to clean" message. I went for a 1hr drive on the freeway to get a good clean cycle in, and it gave a "exhaust filter cleaning" message for ~10mi, then that message went away and the "drive to clean" message came back. I tried turning the van off and back on, then the "cleaning exhaust filter" message came back for ~10mi, then was replaced again by the "drive to clean" message. This repeated several times before I gave up.
Code reader shows ~24% for DPF.
What's going on? What do I need to fix/replace?
