Hi guys, I am a newbie to this site so apologies if posted in wrong section, anyhow, have a 55 plate astra convertible mk5 cloth top. Alarm has a tendency to go off for no reason, this morning at 4.30!! It was ok for first 12 months, then last sept went off about 10 times in a week then ok for a few months and now again a few times recently. Any ideas of the problem. Bloody annoying me (and neighbours) Cheers.
