I personally would not run this b100 because it specifically says in the service and warranty information not to. BMW advanced diesels use high pressure piezo injection system designed to be used with ultra low sulfur diesel fuel. They didn't design the motor to crank out 400 torque on b100. You can use biofuel but specifically states bio fuel is acceptable to 5%(B5). If you use the other fuels I'm sure they'll work and your car is not going to experience catastrophic failure immediately. But if you do own this car and plan on keeping it, your car's fuel system will take a dump sooner than someone not using b100.

even searching biodiesel on wikipedia : "Biodiesel can be used in pure form (B100) or may be blended with petroleum diesel at any concentration in most injection pump diesel engines. New extreme high-pressure (29,000 psi) common rail engines have strict factory limits of B5 or B20, depending on manufacturer."

Your 2003 VW was a unit injector type. Anything after 2007 in VW would be common rail.
