I think this is going over old ground from a couple of weeks ago, but i am having a couple of problems with the alarm on my zafira gsi. A couple of weeks ago and also today, the alarm has been going off on its own, but when you disarm it the car starts 'chirping' at you. I spoke to my local vx dealer who said that it is a power sounder failure and that the unit needs replacing because the batteries in it fail. What i would like to know is, whether this is covered unnder vauxhall warranty as its an 02 car with 30,000 miles, or if not how much its likely to be. i'm sure this was covered a little while ago but i dont know how to get all the old posts up. TIA Tim
