I ran WVO in my 240D for several problem free years. The big thing for running VO is heat and lots of it. I had a lot of empty space in my engine bay for heaters, hose, valves, and such. This is a luxury you don't have. Things are much tighter in your engine bay. And with the higher injection pressure you're really going to have to make sure that your temps are good and high. Coolant heat is great but will still only heat up to our engine's operating temp, which means you still need a lot of electric heat. Personally if I were you, due to the cost of parts for you engine, I'd invest in the gear and knowledge to make your VO into biodiesel. Your car will run this with little worry and no mods, and you'll still see the savings if fuel costs.
