Car began shuttering/vibrating when braking (just like back at 9,000 miles when dealer replaced brakes/rotors under warranty). Was told pads still had 50% life left, but rotors needed replacing. Complained to dealer. Told to call Audi. Told the same thing. Then emailed Dealer Service Manager with all receipts and recent inspection report. Told to bring car back in. On inspection, only right front rotor was "scoring". Dealer replaced both front rotors and pads - No charge
