2002 1.8 20v t gti AUM. my question is...... ive got a knock that happens if u brake quite heavily an when u pull away fast from the front end sounds like it coming from the bottom of the turbo area but its hard to put a defo position on it . everything is new on the front end: all wishbone bushes, arb bushes, suspension, top mounts, inner+outer tie rods, dog bone, someone mentioned about the engine mounts an ive just had a quick look around an found that the one under the air box moves alot, if you put a lever bar in it you can pry it back an forth nearly from one side to the other, is this normally if so what else could this noise be?!!!! HELP its driving me up the wall!!!!
