Got a problem with my ZS if you think you can do anything with it mate car is immobilized at the moment. Locked it up as normal but next morning had following faults....I also found this excellent thread posted by harbottle.
It covers the repair of the SCU fitted to an MG TF115, the central locking relay had failed.
1. Key fob will only open boot and lock car.
2. Central locking button in car no longer works at all.
3. Alarm cant be switched off and car immobilized.
Ive checked the fob with a key reader at work all 3 buttons are sending out RF signals do you think there's anything you can do to help unfortunately dont have any codes from the fob for programing etc
