Whining noise when revving in neutral!
I have a 2002 32i manual (facelift model).
I recently purchased the car for an absolute steal! Obviously with it being 16yrs old it will need some TLC.
I have noticed a sort of ‘whining’ noise when the car is revved in neutral which is consistent to the revs of the car. I can’t tell if the noise is there when driving as the road noise could be drowning the sound out.
I looked online and saw a few posts on possible belt tensioner? But also saw it could be a few other things. Has anyone had any experience with this? If so what would you recommend?
