Just got this in the mail today for my 98 A4 QMS. Coincidently, my Master cylinder on my clutch blew today with only 15k miles on the car. Did I make a bad purchase. I'm worried. The AAA guy said he had to tow a brand new Audi TT back to the shop the other day.

They're machines and they break. Step them up a bit with chips, bigger blowers, etc. and they'll brake more often. Drive your car and enjoy it and when it brakes, call ole Hans up at the Audi dealer and tell them to pick it up and fix it.
