Fra Wikipedia: Volkswagen Group: The 4.2 V8 TDI and the latest 2.7 and 3.0 TDI (V6) engines featured on current Audi models use common rail, as opposed to the earlier unit injector engines. The 2.0 TDI in the Volkswagen Tiguan SUV uses common rail, as does the 2008 model Audi A4. Volkswagen Group has announced that the 2.0 TDI (common rail) engine will be available for Volkswagen Passat as well as the 2009 Volkswagen Jetta.[5]
