Just wondering if it was possible to run this vehicle on bio diesel.I've spoken with VW and they aren't sure and my local bio supplier's helpful advice was "Well there always needs to be someone to go 1st"
Any ideas out there?

I'm surprised this thread wasn't answered ...

My '02 Golf has over 30K miles of its 90K total on bio (from B5 to home-brew B100). I have had zero trouble (shy of tires and routine oil changes). If anything I can say with confidence my TDI runs quieter and smoother. Many report variations in mileage between pump diesel and biodiesel, I would argue this variance would be present between grades and brands of pump diesel alone. Most of my WVO I process bio from is from Canola and my experience has been one of increased mileage and power. I change my oil every ~3K miles and I have noticed a significant reduction in oil soot (so much so I may extend my oil changes out to 5K).

If you local supplier is a reputable dealer and you preform regular maintenance you should have no problem. Change your fuel filter out after 10-20K miles once you initially start using biodiesel as it will clean your fuel system.

I'm not.
TDI's ahve been running biodiesel for about 10 years. Obviously the OP is a clueless newb.
