It's hard to tell without knowing the fuse number because I have wiring diagrams but no layout diagram of the passenger fuse box.

There is a relay called the 'accessory relay 1' but this controls most of the internal accessories, so most things like radio, lighter socket etc should stop working when it is removed.

There is a fuse (F1R) which is a 20A fuse labeled as 'interior multiplex module' that feeds the accessory relay.

I would try replacing the relay as although I have not seen it it cars before, I have seen the contacts of a relays 'fuse together' so that when the relay should be off and the contacts separated, the contact are still closed. This would mean that the interior multiplex module would stay powered on which would cause the drain.

Why do today what you can put off until tomorrow...

Wanna see what I drive? No pics of the latest Passat, but you can see the Scenic II here and the CB1000R here!

Previous Passat here and Bandit here.
