My drivers door has stopped locking/unlocking by remote. It works when I put the key in manually. Assuming this is a common enough issue, what’s the solution?

cheers 👍

Assuming the MK1 remote fob has one, have you checked the battery in it?

The other doors and boot unlock with the fob it’s just the drivers door dude

Check the wiring inside the flexy rubber conduit between the door and frame 

You need a new dook lock mechanism:
