Picked up an A3 DSG 3.2 yesterday. Bit of an issue with the exhaust it seems. When I seem to accelerate hard from when I am stationary or when I go through the gears hard the car makes a noise from the exhaust. Seems Like a flap going up and down noise??? The car dosent make the noise while just revving. Has to be moving or about to. Looked under a car and one of the pipes from the acuator is loose??? Help anybody?
