Had a problem with the usual water in the passenger floor etc on my 2002 Passat and fixed it all and dried it out, thanks to this site. The blipper will still not operate the alarm and central locking even though the key will turn in the lock and operate the alarm perfectly. I have changed the fob battery in both fobs but they flash happily and the car refuses to lock/switch alarm on. I have checked the wiring loom plugs by the passenger A frame and they are all clean and tidy so does anyone know where do I go from here ?
