• Car alarm (astra VXR) is going off intermittently. All times late at night.

    A - it's faulty
    B - it's being tripped by something innocent
    C - it's being tripped by someone trying to gain access

    What do I do?

  • I had this on a Vauxhall Vectra, just googled it and it turned out to be a broken window break sensor on one of the back windows. Easy DIY fix thanks to some forum posts - could well be something like that.
