hi
this is a good question, my airpump was grumbling afew months ago, a garage disconnected it as they couldnt get a replacement before i needed the car. its been disconnected ever since. I believe it runs the aircon/air through the heater?
Does anyone know the BMW part number for the aux air pump?
cheers
steve
