First post /me waves!

I've got a 1996 A6 with the 1.8 20v engine, in recent months its started taping away on a warmed up engine at idle, once the revs are raised above about 1200 rpm the noise goes. Its never noisy on a cold start.

Any ideas (esp from other ADR-ers)?

Whoops just seen you have a dedicated tech problems forum (noob!)
