[QUOTE="jarance, post: 211255, member: 21"] Extract from Bentley Service Manual for E36. The guide below will give your some hint on how to check the ICV. Basically the ICV is an ON/OFF valve. However, by switching the valve ON-OFF-ON-OFF continuosly at various time duration, the ICV can regulate the amount of air into the air intake to control the idling speed. For the more savy people, the term is call PWM (not PMS - you dont want to go there). PWM is short for pulse width modulation. Yes, look or hear the buzzing sound when you engage the Air-con or engage or de-engage the gear.. As mentioned, check the throttle sensor as well.
