iv got a 2007 A4 170 2.0tdi Quattro and I’ve been having trouble with the dpf at first it wouldn’t Regen no matter what I did then after using a additive in the fuel it cleared in normal driving conditions at 20-30mph, I’ve had a intermittent fault coming up of p2002 but when I clear it it goes for a few days then comes back, whilst giving it a full service yesterday I changed the pressure sensor with a decent Bosch sensor, but still have the same error code showing when I scan the car
(P2002 DPF efficiency below threshold bank 1) with no other lights or warnings the dpf light in the computer isn’t showing and when I erase the code it goes away again!!!
Can someone help?
