Can modern direct injection diesel engines run on vegetable oil ?

I read a Golf Plus brochure the other night. It indicated that the diesel
engine can only run on normal diesel fuel.

My old 97' Sharan TDI seems to run better with 5% to 20% SVO depending on
temperature.

Does anyone have any views on this subject ?

I've tried recycled chip fat in our relatively unrefined Citroen ZX, from
the local biodiesel pump. Even mixed with about 10% diesel, it runs like
crap and misfires on starting for a good while. Once warm it's just about
bearable... I'm switching back to diesel.
