Hello there, I need help with some brake problems I have been having lately. My "brake pads worn" light kept on coming on sporadically, usually when the temperature is about 0 - 5C or a bit of moisture out. I checked my pads and it seems about 60% remain. I got eventually fed up with it and went to the dealer to get it checked. In the end, they replaced the rotors and pads. Unfortunately, the day after they replaced everything the brake light came back on again. Took it back to the dealership and they said it was because of dirt on the sensor, so they cleaned it and sent me on my way. The light came back on and have been to the dealership another 2 or 3 times for the same thing. My question is, what could be the problem with the brakes and how do I fix it. I don't want to go back to the dealership for obvious reasons. Any help is welcome. Car: 2006 B7 A4 Quattro.
