What lights are on? The main head (driving) lights and Orange hazard/indicators?

What warnings are on? Any on dashboard?

Is it after starting the problems have come?
Or after stopping?

Is the key out and all switches off?

the driving lights and sometimes the head lights and the hazard indicators go on after stopping and removing the key, is there a fuse I can pull? or relay?

Fuse 54 (30amp) is supply to high &low beam front lights.

But high and low are switched on by relays R11 (low beam) & R13 (high beam)
Which are controled by the BCM and F48 (5amp) fuse.

Hazard lights are controlled by the BCM

The hazard/indicator lights are fed direct from BCM circuit board.
No fuse between lights and BCM board.

My guess is something has fried your BCM.
I would aquire a new BCM (they are quite cheap now from a breakers, last one I bought was £15). And have that programmed to your vehicle.

Also replace the earth strap from your engine to front chassis leg and ensure good connections there, and at battery box conection.

can I cut some wires on one of the bcm connectors? because it draines the battery's
