Hi please help! I have a 2000 e46 318se and there is a really annoying squeak coming from the front of the engine. At first i thought it was simple a belt replacement, but both belts seem fine, good tread, no cracks and tight!
Also normally if it is a slipping belt i would assume when you rev it the squeak would get worse but it seems to disappear when you rev? The squeak only seems to be apparent when the car is idle? Also when it’s idle the revs seem slightly irregular.
I have tried WD40 (a lot!) on all belt wheels and alternator but this doesn’t seem to have fixed it
Please any ideas?
