    I am having weird problems with my car - I unlocked it last night, and the alarm under the rear wheelarch started beeping (not the full alarm!!) the interior lights were switching on and off, the front wipers worked all on their own, and the glass tailgate popped open (its a tourer). The red alarm light under the rear view mirror was flashing, and the remote key stoipped working, but i could still start the car. I couldn't do anything to stop the alarm, so disconnected the battery, but when i reconnect the battery, it starts all over again. Have now had the full alarm going off too, and the boot itself won't lock, or open. Any ideas???? I have had a look at a few boards, and it is pointing to a failing battery, buit why does the car still start!!!! I would appreciate any help

    This sounds like a failure of the GM3 module (behind the glovebox). The best solution would be to replace it.
    Dealer $$$$$. Trouble is they need coding, to your car :-(

    It could be a a wiring issue, you will be best to get a good auto electrician to have a look at the car, a fault code scan of the body control module may also reveal some pointers towards your problem.

    Thanks guys
    My local indy diagnosed a faulty ZKE unit, wich I think is the same as the GM3 module as its sits behind the glovebox and controls the central locking, electric windows, front wipers, self levelling rear suspension if not more. Had it swapped out for a new unit - £400 lighter in the pocket now, but all fixed!!
