Void on Warrenty???
Audi and VW like to "void" your warranty for lots of things. If you chip the car the the turbo dies, don't expect the warranty to cover it. They can and will deny the "claim."
However, they also do crazy things like voiding warranties on unrelated pieces. For example, someone here said their dealer refused to service their TT for a MIL (check engine) lamp because they had a different intake. Legally they have to prove that the mod caused the fault, but in reality you may be the one fighting for that to be honored.
Body kits, etc. are pretty harmless. I think the "safest" performance mod is an exhaust, after that you get into questionable territory. (That doesn't mean a dealer won't try to void the warranty if you have an aftermarket exhaust, however)
