This is the same way the TDI-engines in Golfs and Passats work, and VW has been doing it for about 4 years already, with an TDI(with turbo) or SDI(without turbo) in every model in both VW's and Audi's range. The newest from Germany is a 2,5 TDI v6 engine, producing 150 hp, and enough torque to move a mountain! it is supplied in the A4, A6, A8 models, and most likely coming soon to the Passat.
