mine started sticking at 80k. Had to get it cleaned out. The car was still under the warranty from where I bought it which was lucky. Didn't cost me a penny
Some sources say it stands for "Variable Nozzle Turbocharger". A set of movable guide vanes in the exhaust turbine change the size of the exhaust opening, making it smaller at lower gas flow volumes (lower revs) to keep up the gas speed through the turbine, so getting it to spin up sooner i.e. at lower revs.
It is fitted to my TDI 110 engine - I don't have a full list of the engines it is fitted to, though. Certainly not fitted to the TDI 90. I think all the PD engines have VNT turbos, but not sure.
The turbine is sized for the gas flow at full revs and so has no wastegate.

yes, its fitted to all PDs and all 110s. It wasnt fitted to 99% of the non PD 90bhp TDIs apart from the later models of the Galaxy/Alhambra people carrier. It is operated by vacuum.
