Bought a 2000 Jetta TDI

I drove a TDI stick in '98. I had to run out the r's a bit to get it going, but I liked it. We didn't buy it then as we went a different route.

The mechanism that moves the variable inlet vanes or nozzles in the turbo (VNT) have a tendency to bind. What actually causes this is still being debated among TDI owners. For whatever reason when a replacement was needed the poster decided to upgrade to a bigger air mover. This is probably a prudent move considering the re-mapped ECU chip and the higher flow injector nozzles already installed (and possibly contributing to an early demise of the OEM turbo).

So, what were the mods for? Is it a regular wearing out issue, or for a little better overall performance?

The mods were for performance, but I have also improved economy.

Lug nut, I agree that after I had the remapped ecu, a buddy advised me to have a boost guage and a manual boost controller installed. I hadn't and the original turbo went south at 160K, I was not surprised, not happy either.
I am much happier now with my VNT 15/22, economy and performance.
