Help Please Fuse: Control unit for vehicle electrical system

Does anybody know what the below fuse is for?


In the owners manual it says
"luggage compartment,
fuse carrier B (black),
No. 11 'control unit for vehicle electrical system',
20 amp"


VCDS won't connect.
Tried a brand new batter with no luck.

A fuse in the boot keeps blowing
-Control unit 2 for vehicle’s electrical system
-20 amp

In the owners manual it says
"luggage compartment,
fuse carrier B (black),
No. 11 'control unit for vehicle electrical system',
20 amp"

I put a brand new 20 amp fuse in then connected the battery. The fuse instantly blows.

All dash lights are off except the
-electric handbrake switch led (which doesn't release the handbrake)
-light on dash showing handbrake is on.

No power to the stereo or any other screens.

I can put the headllights on which also turns interior leds on and also i can use the windows

So power is there.

However the key is stuck in the ignition but even trying to start, no power at all, all dash is powerless.

So I unplugged the module in the boot (BCM2?) the code was 8K0907064DP - when I unplugged the power the fuse stopped blowing.

I did a VCDS scan but as there was no power I saw a trick online to wake up some modules without any power from the key.

Thats just what I got sent mate. I'm unsure what vcds version they're running.

A friend is checking the car over and forwarding me the findings. I'm just being the middle man and pushing everywhere as its my car.

If you feel that is illegal, i can remove it?
