Does anyone have any TSB, any Audi document or even a third party source that describes DRC failure (ie clanking, clunking, thumping sound, leaks, etc) and how such a failure can compromise safety, value or integrity of the vehicle?

If so please post for it for me. Any and everything (no matter how insignificant) would be greatly appreciated. Thanks everyone for your help in this matter.

If you would rather email it to me instead of posting send to this address:
