The oil pump sprocket nut backs off, then there is no oil pressure, and the result is complete engine failure. I had to replace the engine. Before installing the new engine I welded the nut to the sprocket to stop it happening to the replacement engine.

This issue has been seen on many BMW i6 engines.
