hi....today i was installing an amplifier in my 1.8 golf driver. i disconnected the battery an hookep up the power cable for the amp, but after connecting the battery back up, my alarm seems to be constanly armed....if i open a door or the bonnet then the alarm will go off. locking and unlocking the car has no effect...also what i presume is the alarm light in the car (small red led) is permantly on.....i dont have much experience with golfs and so am at a loss what to do. everything worked fine before disconnecting and connecing the battery....hopefully someone can shed some light on this?? thanks in advance, any help is appreciated as i cant start or drive my car because of this!
