I would think its either a coding problem or a door connector.

Mine has started to do this a few weeks ago after coming back from the dealers. I'd be interested if someone knew the answer

Probably coding problem as the drivers door has a control module to control all windows / mirrors / locking etc. and based on if this is orientated as left hand drive vs right hand drive will give you these problems. All sensor swithes on locks will be routed through the respective door control units and communicated to the convenience module over CanBus, so doubt it's a wiring problem.

Check Coding for "+128" as listed below,

I changed the coding and hey presto it worked, but it stopped my remote windows and alarm blip sound from working.
