What could drain my battery?

On my '83 3.2 carrera you can operate the windows & sunroof with the drivers door open without the keys in the ignition. When the door is closed the relay is de-energised.
Good luck.

On my '83 3.2 carrera the plug isn't connected to anything, not sure about the 930. The RHD cars don't have the factory keylock alarm in the door, maybe this is due to that connection, not sure.
