Yours a different issue then, thanks for clearing that up. The usual issue people have, is misfires on stock cars running a map only on cars that were build in 2008. I don't know exact dates though. After a point Audi stopped using softer springs.
The problem with warranty, usually, is that it only occurs on a maped car. So I can't go in asking for springs, except if there is a service bulletin or a recall of some sort? If you can get a little more info on that, it would help a lot of people here :icon_thumright:
