Differential pressure sensor or not? – 1.6D is bumpy

Hello everybody! short history: At the beginning of the year the box is already like a goat “ridden”; so new DPF pure. When everything went a long time well until last (2 weeks), it has bucked again, although much less. the symptoms: – only bucks when it is cold (we have here just 15-16°C early) – massively only shortly before regeneration – after regeneration after “daslaune” and clearly less to not at all – always around the 2000RPM – feels like short-term “breath standstill” respectively. “mortorbrake” “full cannon” for fractions of a second – error memory doesn’t give anything How did I get on the suspected differential pressure sensor? -> I read a lot about the week. However, it was difficult to find anything clever about these concrete symptoms because in fact every forum side-war scenes were opened and the threadstarters never reported again. But the pressure sensor somehow crystallized out. So! To them spezialists ode r possible “victims” of the differential pressure sensor: fits my suspicion or is something quite different? So slowly the fun at the box passes me: DPF, “intake art”, drive shaft and wheel bearing in 6 months… Greetings and thanks already! ps. before here again the “sparing pigs” the topic carpern: – DPF -> volvo – wave -> volvo -> built in by my housemech – camp -> what clever of my housemech
