Evening folks. Had the car in with the stealers today for its service, all went well apart from two issues. One been a rusty exhaust clamp and the second to be told was the front discs that had worn to the Audi measurement of 125% worn. Anyway I’m going to replace them myself but I seem to be getting a few sizes popping up. 314mm, 320mm and 345mm. What size are on the 2015 B8.5 S-Line Tdi 150 bhp model.
