E65 oil dripping from the front of the engine - where can the leak come from?

The most common leak points are the valve cover gaskets, which harden and leak over time, and the vacuum pump seal at the front of the engine. On the N62 engine, a leak has been found at the valve cover gasket. When one gasket is renewed, check the others at the same time, because more leak points may turn up.

Where does the E65's automatic transmission leak oil from?

Transmission oil often leaks from the electrical connector. Other leak points are a cracked oil pan and the gasket between the mechatronic unit and the transmission housing.

Is replacing the transmission oil pan gasket enough, or does the whole pan need renewing?

The oil pan is plastic, so it is replaced as a whole. The gasket comes with the new pan, and the filter is in the same package.
