    If it's the turbo motor which I think it is I would look at the turbo coolant hoses, famous for leaking

    There are plenty of places that coolant can leak from. Pop the cover off and start looking. A pressure test can help locate leaks, but normally on the N63 engine, they show up pretty obviously. Check the coolant y-pipe "vent hose" that's down below/behind, and to the side of the alternator. The plastic y-pipe is notorious for breaking and leaking coolant. As well as jclausen said, the turbo coolant lines right on top are notorious for leaking as well.
