Hello, I got a V50 2.0D with DPF last Tuesday. Year of construction is 11/2004, km-status at the moment 87,500km. Yesterday suddenly the following problem occurred: After starting (engine cold) the vehicle suddenly has almost no power. It is as if the car had no more turbo. Speed maximum 2500prm and absolutely lame! Well, that goes well with the car! I have the diagnostic device “PPC Diagnostic System” from BSR. That showed with no errors in the motor electronics. Now I made myself a little smart in this forum times, as well as I could. Additively seems to have been refilled at 60,000km. At least there is no indication available that would indicate a missing additive. In some cases I have heard that either the DPF can be dense or a sensor provides false values and the BC then thinks that the DPF would be dense and the engine performance thwarts. Where does the sensor sit? Can you test the function somehow? How expensive would it be to change? Do otherwise have an idea of what does not indicate a mistake?
