Hello all, does anyone have any info on replacing the central locking control unit also known I believe as the door actuator on a 2005 3 door k12, as I have previously posted I have a problem with a buzzing noise when locking the car using the remote. I have recently purchased another unit which comes with the two cables but looking at the cable which attaches to the door handle this looks tricky, does anyone have any tips on the best way to go about fitting this item? Thanks for any help.
