I had my vaccum pump changed and once I obtained my automobile again it started to make a squealing sound.
This sound occurs after driving for a bit then coming near a cease at purple lights or parking. I seen its taking place between 1-2k RPM. It can squeal till I am going above that RPM or the auto off function turns the engine off. Upon restarting it goes away as effectively.
I believed it is likely to be the timing belt but it surely nonetheless occurred after I modified it.
This can be a 2013 328i
Anybody ever had this occur to them?
