It is either going to be a can bus error or connector or earth issue or water ingress.
Usually with can bus faults switching off usually cures it on restart but try disconnecting the battery and reconnecting.
Water ingress to one of the ECUs or its connector is quite a common issue in this case it looks like the body control computer or its connector or
the earth point or its power feed.

Can of worms, wiring faults are the hardest to solve.
Have you got an OBD scanner? Mine has helped me no end!

Daughters Citroen C4 did similar during the first cold snap this winter, I put it down to condensation in the connectors, I cleaned as many as I could
get to without major strip down, and the faults seemed to go away, I used contact cleaning spray I used to use in vintage Jukebox relays.
But, as Coozer says so difficult to find the real cause and be sure its fixed, plus the fault codes indicated the ecu was suspect, she did the
sensible thing and traded it in, she needs it for work and couldn't risk it failing.

"Normal" OBD scanners do not work with Citroens. They need a Lexia3.
As said electrical faults on modern cars are a nightmare.
