chirping sound from the engine

(1/2) > >>

dansmith180:
As above there is a squeaking/ chirping sound from my engine, it's mostly on cold starts but a few times I've heard it after long drives still. It sounds like it's coming from the left side of the engine where the cambelt is, I have also WD40'd the aux belt and it didn't help.

I've done some research and it's probably a belt possibly cambelt but it was replaced 24k 27months ago so should be fine? Also I haven't heard of a cam belt still squeaking when warm?

Any suggestions welcome, thanks.

Redemption:
One of the auxiliary belt pulleys perhaps? Had a similar issue on mine and that's what it turned out to be.

Andy:
Had the same noise and it was the auxiliary belt

On the 2.0 TFSi, it's normally the cambelt tensioner that squeals when cold.

Its weird that it starts again though after a long drive? It was quite loud last night after nearly 2 hours of driving.
