If this is an M30 engine, there is a small plate at the back of the head that is attached with a couple of bolts and a gasket.
Inevitably, over time, the gasket there starts to fail and you get a leak out the back of the head. If you look closely there, perhaps with a mirror, it should be very obvious whether there's a leak or not.
Now for the bad news - the only way to get at this plate is by pulling the head. Honest.
