a4 battery drain, please help!

My A4 is draining the battery at 300 milliamps, depleteing it every few days. It seems to be from the window switch lights that are on all the time. The windows and the sunroof work even with the keys removed, the door opened/closed and door locked. Every once in a while the windows and sunroof are found open. Once the stereo was found on with the doors locked. Have disconnected the remote receiver also but it still happens. Anyone have a clue?

Check the coding of the centeral locking unit with a VAG-COM and fault codes too.

Clearly your retained power is staying on...

could be as simple as the door switch, but do the VAG-COM.
