Does anybody know how long the anti-corrosion warranty is on A3's? (audi's in general?). As i didn't buy mine new i'm unsure. When I was washing yesterday i'm sure I found some bubbling on one of the doors /ubbthreads/images/graemlins/shocked.gif /ubbthreads/images/graemlins/frown.gif. I'm sure i've read somewhere there is either a 6 or 10 year anti perforation warranty?
