Yes, BMW has been using Direct injction in diesel cars since about 1998. Thats why the piston is shaped so funnely in the middle, to properly distribute the fuel.

What it means is the fuel is injected directly into the cylinder, and not into the air intake manfold just before the valves like the older engines do.

Your car has 2nd Generation common rail as far as I know
