2002 E39 Idle Control Issue
Need some help to diagnose idle issue please - after driving for few miles and then stopping for 10-15 minutes (engine off), then restarting car, the idle becomes irratic and cuts out when opening the throttle. Leave it for few minutes (try ignition a few times) and then all OK.
Have taken it to garage and they *think* it may be idle control valve that needs replacing but not guaranteed.
I just need to check if there is anything else that may be causing the symptoms - it only happens when car is warmed up (10 mile journey) and then switched off for few minutes. (Works fine from cold engine).
Any comments appreciated.
