2004/5 B5 Passat 130TDi.

Any advice of the minimum components that should be replaced if I have suffered bad clutch judder for 10-15K miles?

Don't know what the cause is yet, but VW agree its faulty and will be changed under warranty. It could be flywheel or contaminated plate by oil leak, or something else!

But I am concerned that they may not replace connected components that may have been damaged by the problem.

Any advice on what would be reasonable to insist upon?
