Hey everyone, I am extremely new to Audis and anything that isn't a old muscle car, and I now need to get new rotors and brake pads for my car. I have a friend who has a mechanic shop that I trust completely to do the new installation for me, but when I was about to buy the parts they asked if my brake pads had sensors on them or not and basically told me to go to the Audi dealership here and have there techs look at it. SO I am wondering if anyone know how I can find out weather I have them or not? Thanks for your help guys!!
