406 lxdt 2.1 central locking locks then unlocks

[Johannes]

When locking on the drivers door lock it locks and then immediately unlocks. On the passenger door i can lock it and it holds.

Where to start???? Thanks.

Mine did that when one of the other doors wasn't shut properly.....

I checked all the doors. The issue is that I can activate the central locking from the passenger door and it holds. But walk around to the drivers door and clunk (lock) then immediately kerchunk (unlock), so the system sees all doors closed when locking from the passenger door, but possibly not from the driver's door....
