as Neil50 stated, you really should change the Top hat, the release bearing slides on this and it gets scored quite badly
You should also check the ball ended pivot bolt and the cross arm, if ANY signs of wear then replace them as they are a cause of clutch bearing failure, and are cheap parts. If ordering from Audi there is a spring clip that MUST be ordered seperatly
Also suggest fitting an LUK clutch as it was originally used by Audi and mine cover 272K miles and was only changed due to clutch bearing failure
