For a while i have had a problem with the factory fitted alarm to my S reg astra, when the car is parked up and ignition has been turned off, the alarm beeps four times (obviously relaying that there is a fault), but even when im driving it beeps. Also sometimes i can leave the car unlocked and not armed and the alarm goes into a series of beeps. Took my astra to Dixon's (Vauxhall) and they claimed it was the sonic sensor and charged me £90 for the part !. went ahead and let them fix it ... first night and the alarm is going off again !!! has anybody got any idea what's wrong with the %%$%**~ thing ??
Many thanks
Simon
