Could just be a loose vacuum line on the pump unit.does it lock all doors when locking but only open the drivers door and boot?also check for water ingress at the connections on the pump,that's what killed my pump
No it doesn't lock only does the same as opening drivers and boot
Ok I would first check the central locking pump unit to see if any off connections are corroded or wet,rear lights have a tendency to leak and fill the pocket where the pump sits corroding the conectors
Might be worth giving it a night in an airing cupboard,Ive also heard of people putting a small amount of copper slip on the connection terminals,ive not tryed this myself though.Hi mate had a look it seems abit damp
try unlocking twice? You can code the pump to only unlock the drivers door on the first press.
Do you have a problem with your central locking Carl?.
