Hey people I drive a Volvo v 50 2 liter diesel Bj 2008. I have a problem, when driving from 2500 revolutions an indicator goes on in the display (motor system maintenance required) Then the engine switches into the emergency program, so I can not get over 3000 tours. If I turn off the engine and restart then it runs again and then it switches again into the emergency program. Was with it already in the workshop, they connected the then to the PC, and set the error back again. According to PC the soot particle filter is closed. But the car has only run 70,000 km. Is that so right? And if so what can I do so that I don’t have to buy a new one. The workshop has said a good blow-off and then it will be again, but that’s not possible because it only drives in the emergency program. I also saw this coming out of the injection nozzle diesel. I don’t know any more. Can anyone help me?
