My first forum forgive any faux pas I may commit. My 2002 A4 1.8 is just a few months out of warranty and the steering rack has failed and a non dealer mechanic has told me the tensioner is bad and could be a prelude to a sludge problem. Anyone know the chain of command at Audi to expedite this? Or any advice? I bought this new, never wrecked and did double the oil changes at the dealer! Audi Girl
