My A3 (info in sig) has started to make a noise from within the engine bay. It's quite hard to describe but it's a squeeking sort of noise that sounds like a belt and kinda like a turbo, although mine isn't a TFSI. The pitch of the noise increases as the revs get higher.
It's currently on 72,000 miles and is 6 years old so I know the cam belt and water pump need to be changed (getting done after next pay day). Could it be this that's making the noise? I don't want it snapping as I know I'll be pretty much buggered if it does.
I know it's pretty difficult to diagnose without hearing it in person, but any help would be appreciated.
