Bit of a strange one, the car will happily sit on the drive alarmed all day long, through the evening and into the night, as soon as it gets to around 3-4 in the morning the alarm goes off, i asume it may be because its damp at these times? any idea what may be causing it, its woke me and my neighbours up on numerous occasions over the past 3 nights, once it starts it then goes off intermittently, only way to stop it is to not lock the car
