Hi

Had a flick through but couldn't find a related thread, apologies if there is!

My A6 TDI auto/multitronic is suffering from a high pitched squeak/squeal noise. Appears to coming from off side engine bay. Only does it under load, low down in each gears rev range. The problem stops when the engine heats up.

Turbo and brake assembly have been ruled out, have been advised that it could be loosing air somewhere or one of the valves within the egr pipe work somewhere. The egr has been off and cleaned recently (right hand side as you look in)

Tried to replicate it when up on the ramp but it wouldn't. Only when the wheels are on the floor and driving. Anyone have any clues? There's a lot of the pipe work under there to check, any advice welcome guys!

Thanks
