Meal together, last Wednesday (of course exactly when you want to go to the airport or on vacation) I noticed a significant power loss with my S40 2.0D Bj 2005 (157,000 km). The engine only turned up to a maximum of 2800 rpm and managed to reach the 110 km/h even in the 6th gear. Since I had practically no other choice, I still went to the airport. Yesterday I came back and made my way home. At the first 1-2 km he had the normal Power, after that the game started from the front. I did not have the DPF replaced until today. There is still no error message in the cockpit. Today I am in the workshop with the vehicle and the error memory was read out: OBD: error code P2002: soot particle filter bank 1 – efficiency under minimum engine: error code 8194: soot particle filter – function faulty According to free workshop the DPF should be replaced. Recommendation is exchange for original part, additional the pump in the rear part of the vehicle, which is connected to the filter. The error memory has been deleted and I now have power again, but who knows how long… So I will probably have to do it. But since I don’t have to give away any money right now, I ask myself to what extent? I have already read here and there that it can also lie on the differential pressure sensor, which would then be significantly cheaper. If it is not on the sensor, the DPF would have to change it. rden. What about the workshop’s suggestion that the pump should be replaced directly? And what does it say for and against a purified DPF? Who knows the matter and can give me some advice so that I can get out of the number with the lowest possible cost? Thanks in advance.
