A4 1.9 tdi 1999 Since I've had the car (3 weeks) whenever I lock the car wether I do it by the button or by the key the alarm doesn't shut up! It doesn't go off straight away, for example last night I got home at 10pm, locked the car by the button. By midnight it was going off! I had noticed the wires that go to the squishy bonnet sensor thingy lol (please excuse my fantastic descriptions) had come off, so I put new connectors on the ends of those wires and plugged them back in. Still no difference. I haven't got anything loose or hanging inside the car. Any ideas guys?
