Right just changed the rear pads and dics on my a3 but couldn't see we're the plug goes for the brake pad sensor spoke to the shop were I got them and they said there may not have them on the back so cut it off but the light is still on the previous owner changed the front pads and cut the sensor on the front passenger side an twisted the connection to form a loop so is there one on the back as the light on the dash is still on anyone know we're this is??
