Ive been having on and off issues and finally got to replacing the tstat (looking at it it was the original one) now my dpf is essentially plugged, im going to try the liquid molly dpf cleaner and was wondering if anyone has tried it and any tips how to do so. Also i saw on a e90 post a guy punctures a certain vacuum hose which tricks the dpf into constantly doing a regain cycle once at operating temp which would be ideal in my situation.
Any help always appreciated
