Hello all,
I have recently bought a 2003 ARL pd150 mk4 golf, its got 200,000 miles on it and an issue i cannot seem to diagnose is a a turbo whistle/ boost leak, i've had it on ramps revving tf out of her feeling for the leak, and listening however i cant feel anything, and its not really loud without road resistance. Any help would be much appreciated. Hope ive done this right, new to Mk4's and the forum
