I own a 2005 Audi A6 2.0 TDi saloon, with 155k miles under it's belt - had the car from new. Cambelt recently replaced, and oil pump conversion kit fitted last month.
Recently, I've noticed a rattling noise from the clutch, at the top of it's travel. No noise when stationary, or when the pedal is fully depressed - it becomes apparent just for the first few centimetres of travel, and then fades quickly away when fully pressing the pedal down. It's normally just a steady rattle, but if you hold the clutch in a certain (very small) area at the top of it's movement, the noise is more of a grind. It's not particularly loud, but now I've become aware of it, it's more noticeable than ever!
Clutch is not slipping, it doesn't appear to affect the car's operation in any way, just an annoyance. Any thoughts on this? Is it repairable, or is it full clutch replacement time? (I've been reading up on bearings as a possible issue?).
Expected costs would be useful to know too - I notice Audi offer clutch replacement for £749 under their fixed servicing price scheme, and my local specialist quotes £499 in their literature - no idea what either of these include though.
Any thoughts appreciated.
