S4 forum has a list of S4 engine and tranny failures. Just wondering if RS6 owners have experienced anything similar.

early in the development phase. At least one customer had an engine replaced by Audi under warranty after the chipped motor blew up.
I've heard of one tranny having problems.

One car has had pre-delivery problems that are ongoing and another has drivability issues.

No problems like the B6 S4 at this point.

problems, the lockup clutch was slipping and causing really bad fuel economy (even for an RS 6). Replaced under warranty.
