I have a 3.0 tdi Quattro with the larger discs 1ZL up front and my sensor has been chirping away the last day or two. I reckon there is loads of meat left on them but the dash is lighting up like a Christmas tree so been looking for new pads all over the place but have encountered some suppliers have several pads available albeit with serial numbers which are near identical bar one digit. If I made a list of them all id be knee high in the possibilities. Anyone recommend where to get them from with minimal fuss and maximum feedback please. Cheers.
