The S63Tu has a complex engine breather circuit with valves to open/close the vents depending on engine parameters. Perhaps it could be as simple as this system not functioning as it should.
I would get it looked at ASAP. If you can't spot an obvious leak, then that oil is being burnt by the engine, which has a number of bad side effects, including potential CAT destruction.
