2014 Audi RS5 with 20,000 miles w. shuddering of brakes. On Oct 3. 2015 my local mechanic took all wheels off and we inspected the brakes. Visually we saw no problems, no signs of overheating, or concerns. He suggested I take it to the dealer. On October 9, 2015 I took my car to Audi of orland park and after an inspection, the service manager stated that the rotors have high and low spots, that I need new rotors and brake pads, that Audi rotors must be replaced at 20,000 miles -he has replaced rotors every 13,000 miles on some customers cars, that Audi brake rotors are thinner than other brands and that there was heat damage to the rotors. Remember that just 1 week earlier, my local mechanic and I visually inspected the brake rotors and there was no bluing. The only thing the service manager was able to show me was brake pad residue on the rotors, nothing else. My 2 mile commute at a maximum speed of 30 mph involves 2 stoplights. This involves no overheating brakes, no hot brakes in stop and go traffic. I am gentle on the brakes, I don't slam on my brakes, and have never felt the ABS activate. My local mechanic deemed that it is highly abnormal that a rotor needs replacing on such a low-mileage car driven as I do, and that it very well could be a manufacturer's defect. If so, it should be done under warranty. If Audi brake rotors are thinner, thus weaker than other brands' brake rotors, it is an engineering mistake on a 4,000lb GT car designed with torque vectoring and for use on european highways. If Audi brake rotors are getting warped without abuse it is a manufacturing defect.
