Hello Audifans, I’m new here and hope you can help me. I have an Audi 80 B4 Avant Motorkennbucvhstabe ABK with 85 kw. The engine doesn’t spin round. Should it be called fluctuating in the stationary gas between 300 and 900 u/min. Even if I drive it shakes correctly and in this phase it also smells like oil. At Audi I let him read out and the display said Lambdasonde and air mass meter both static. But now comes the funny thing: I had the following parts renewed by a workshop before: distributor completely new, candles new, ignition cable new, oil new, air mass meter also new, Lambdasonde also new. Does anyone know what that can be? Perhaps the control unit or any other sensor or relay? I am really frustrated. Of course my mechanic finds the mistake when he is busy one week ago! But you should pay for it??? I would be really happy if someone can help me here? I love my car but if it’s so bad that I don’t think about it’s new help.
