Well I eventually got the central locking fixed on my Landrover – with it being unlocked for the last 7 months.
The diagnostics (yellow lead) was saying it was the passenger sill switch. There isn’t a passenger sill switch there is a switch in the actuator on the drivers door, but nothing on the passengers.
It seems the cause of the problem was an interlink between the keylock and the actual lock.
Remove it (I don’t have a key anyway) and it’s fixed. Woohoo.
