Ducato 2014- central locking not working for rear only

[Messyjessy]

Hi,
If have been searches the deepest caves of google to find a solution for my central locking problem. Only the rear doors are not locking automatically, not by the fob not the driver button. I have seen some posts about battery and fob resets but no luck.
I fear it might be the locking unit or the wire. Any ideas how I could test this without ordering expensive parts? Any suggestion or help will be very welcome. Cheers

My hab door won’t lock with central locking if the key slot has been left in the wrong position. Can’t remember which way, either vertical or horizontal. But it only works in one position.
