Welcome to the forum.

 

You could try a battery disconnection, waiting for a few minutes and reconnection to see if this helps. I have found the following method noted in the Technical section Common Problems pinned post, does not give odd electrical problems:

 

16. Odd electrical problems caused by wrong battery disconnection procedure.

If you need to disconnect the battery and not do a BSI reset procedure, I have found the following has not given me any problems on a 2004 and 2007 C5 and a 2003 C3:

- remove the ignition key from the car

- open the bonnet

- wait a few minutes for the BSI to shut down

- disconnect the battery negative terminal

 

When reconnecting

- ignition key out of the car

- reconnect the battery

- wait a few minutes

- insert the key in the ignition and wait a minute

- turn the key to the first position and wait a minute

- turn the key so the dash lights come on and wait a minute

- start the engine

- take the windows down and up to reset the anti pinch

- reset the clock (and radio on the C3).

Before you disconnect the battery lower the drivers window, do not open the door on the reconnect list instead put the key in the lock through the open window, turn on the sidelights to balance the electrical output then turn the key to the first position and hold down the lock button for 15 seconds. This sets the locks to the key
