Re: central locking any ideas ?
This sounds as a broken wire problem. Can you lock/unlock all doors using the passengers lock/unlock switch? The system is divided in the drivers door module, which only switches the drivers door lock motor, and the passengers door module, which switches all other 3 doors and liftgate lock motors. The passenger door module also has the receiver for the remote locking/unlocking function. Many times problems occur due to a broken wire in the rubber door boot, so i would start having a look at both front door boots. Also a loose connector/wire on the passenger door module could be your problem. If this is ok, you would need a DRB III scanner to look for faults.
