Hi there,
My mums '52 plate Astra 2.2 has recently been suffering with the alarm randomly going off. I've checked to make sure there isn't anything hanging inside the car that might be triggering the ultrasonic sensors and all looks good. After searching the forums I've found that it's probably the 'powersounder' unit that's gone faulty and that it can be fixed by unsealing and resoldering in a new battery but I'll probably just buy a new one from eBay or something.
One thing though, when her alarm goes off I notice there's two tones of siren - one sounds like her horn and the other sounds like what you'd expect a car alarm to sound like - as well as her indicators flashing. Would both types of siren going off still be caused by a faulty powersounder or am I looking at something else here?
many thanks
