C30 rev whine
So not long had my 2.0 petrol manul C30 R Design. I've noticed a whine (not squeel) from reving the engine or pulling away. I then done some digging and seen it might be AC compressor?
I turned AC off, tried some revs in neutral and the noise is gone so am I right in saying its likely the Air con compresser unit? Still works but wondering how quickly I should attend to it. I knowsome cars have separate belts for pump etc so just want to see if this would cause any further damage or just stop something else working? Thanks for any info! |

Thermal expansion valve can also cause a noise, if bad. I read some posts recently in the P3 shape Volvo section about an a/c hose that can be changed. The one that was fitted from the factory had a tendency to vibrate, causing a whining vibration almost when the a/c was on. The new replacement hose has been adapted to resolve this. Whether this is an option on the C30, I dont know.

Hi

Or could it be the tensioner or belt driving it? The AC compressor might just be putting extra load on the belt and tensioner causing it to whine?
