Ive got an 8p 1.9 TDi, and when it gets up to 2 - 2.5 thousand revs the sound of the engine goes from being the normal diesel rumble to a higher pitched noise for a split couple of seconds. which also makes the centre dash console vibrate??
Ill try and get a video up of the noise but just wondering whether anyone has experienced the same thing.
I thought it may well be he turbo??
