eurotec :

Hi, it sounds like your central locking pump may have failed. You should first check fuse 62 in the rear fuse box to see if it is blown.

If the fuse is good you may be able to remove and install the fuse and get the pump working again. Sometimes that will reset the pump. If not I suspect you will need to replace the central locking pump (PSE module).
