I could be wrong, but I think what your hearing is turbo chatter. This is when the turbo "Stalls" or so I'm led to believe, This is not good.
Is it possible to get waste gate chatter on a TDi ?
I thought you needed a throttle butterfly to close for chatter to be created ?
Diesels don't have a throttle butterfly.
Yer your right in what you say the noise that you hear when you lift off the gas is the turbo stalling , although this isnt particularly bad it does send small shock waves through the turbine but they have very little or no effect, Ive run many petrol turbo cars in this way with no problems at all 2x reasonable power cossie's / r5gt etc etc Just intrested to know if you get the same effect on the diesels i presume you do but was just intrested to see if any one else was doing it..

Yes you do get it. I've got a standard exhaust (so no noise from that) and have a Honda S2000 filter sat on the end of my MAF. Due to the VNT you don't always get a 'good' chatter since the angle of the blades obviously adjusts. But, catch it just right and you do get enough noise to get looked at oddly by pedestrians.
