Unlikely, you need to check each fuse to see which one is drawing current when everything is switched off.
This will give you an idea of where to look.

It's the switch to operate the lights.

The answer is none at all The LSM as pointed out is the light switch, and if the background LED lighting is illuminated continuously, it prevents the BCU from entering standby, meaning the current draw is circa 2.5 A, rather than the normal 40mA. The test for this is to look through the window with the car locked up, and see if the symbols around the light switch are lit up Brian |
