Dear all,
I have a 2008 320i with low milage of 55,000 km. I am, experiencing a strange small cracking noise right after engine start (not only cold start) with fan on or off, but AC compressor off. The small cracking noise will disappear after I pressed ON the AC button. The strange thing is, the cracking noise WILL NOT come back if I turn off the AC a while later.
Would that be any relationship with the compressor clutch somehow touching each other during the engine start. And after I switch on, and off the AC, the clutch moves back to a total separation position so that it does not touch each other anymore?
Or, is there a problem other than what I am guessing?
Anyone has similar problem?
Thanks a lot!
Jack
