Any one else experienced squeeky brakes with the RS3? Only does it at low speeds (in traffic etc). Its really loud and quite a low pitch. Never had a car with drilled discs - is it something that often happens with those? Cars done less the 1000 miles - could that be a contributing factor? Trying to make time to see the dealer about it and to sort a couple of niggling rattles. Just wondered if anyone on here had experienced this.
