2000 BMW Z3 Question: Idle Air valve control

Suddenly my idle air valve control went bad! What is the common reason for this to go bad? Also, approximately how much should it cost if I take it in to a shop? Thank you, -
Answer 1
The idle air control motor takes about an hour to change and the part is about $185. Carbon build up normally causes the slider in the air control motor to bind up, on some cars you can just clean them. -

Hi, would this problem cause the car to back fire and kill revs, there is a buzzing noise coming from a black box top and centre of the engine is that the part being discussed. Regards Jack -
