Having problems with your 2002 Audi A4 ?

High Pitched noise

\015 There is a high pitched noise coming from the underside of my 2002 Audi A4. This is not coming from the engine compartment. It makes the noise while idling and is not affected when I accelerate. It started this winter during and unusually cold spell...It went away when it warmed up and now its back again, This only happens about 50-60 percent of the time...Any thoughts what might be causing this.\015 Posted / edited by AnonymousUser on : 23-10-2017

Answers :

I had a high pitch noise, didn't sound like it came from the "underside". Turns out it was one of fans that had little chips in the blades? My Audi dealer replaced it, and it's fine now.
