I replaced the central lock switch. No change, central locking and key fob still doesn't work, except rear hatch still works. Checked error codes on the body and again and same codes. The error 51 on the windscreen washer pump short circuit is a clue there may be a short somewhere but the pumps front and rear are working so why that error is a mystery, and the first code "not found" I have no information how to interpret. So, I know what doesn't work.
