Squeaky AC me thinks!?
Discussion
Hi Al
Coul anyone helps me out a little? please
I've got an E90 320d 2007 model M47. Past few days when I pull away, I get a noise coming from a belt. When I turn the AC off completely and repeat a slow move away there is no noise. I've had a crank pulley go in the past and I've known it to be noisy and also happen when the AC is on or off, well so I think!
Tonight I put some water on the AC belt then WD40. Both times when I tested the car there was no noise. Once the substances had both dried I found the noise came back. The noise itself is a squeak from a belt but it only lasts a few moments once the car has pulled away and gained momentum.
I'm just looking for advice if anyone else has had the air con belt where out or do you think another crank pully could be going.
Notes on the crank pulley: I had it changed 2 and half years ago. I do around 30k in my car a year. I put my fingers round the rubber and it seemed soft not cracks or bumps. Not pieces of filing floating about!
Sorry, this is long winded needed to write all this down while it is fresh!
