What year of TDI? We ran a '99 TDI on biodiesel for a long time with no issues. I'm not sure that I'd run SVO on the TDI pumps, but biodiesel should not be an issue. I've found that many diesel mechanics have what could best be called an allergic reaction to biodiesel, and blame it for all sorts of engine problems. One blamed SVO for an old mercedes being slow claiming that it had ruined the car... and it was only properly heated 180degree SVO in this particular one too. I suspect that it was having a non turbo 65 horsepower engine in a 3500lb car at 9,000 feet elevation that made it slow, myself..... I do know that some injector pumps are not particularly strong (I've heard that the lucas ones are on this list, but not sure of others), and could be affected by a fuel with higher viscosity. So, perhaps... but I had not heard issues with the early TDI's before. I have heard that the PD TDI's may have issues with polymerization, depending on the iodine number of the biodiesel.
