  • alarm keeps going off

    picked up a 61 se nav sports tourer 2 weeks ago.
    every now and then, the alarm will go off while the car is on the driveway.
    just happened again tonight, and it was 3 hours from when it was parked up. the last time it went off, it was about the same amount of time from the the car being parked up.
    no attmpted theft, can see the car from my front room, live in a quiet area.

    The rear boot on the ST has a motor to fully close the boot door. If the boot door is not closed sufficiently the motor will not engage and the alarm may think the door has been opened. I've often closed the boot, then hopped into the car, closed the drivers door, only to hear the motor closing the boot - the air pressure on closing the drivers door triggering the boot switch to close. A possibility.

      its a powered tailgate, so always fully closes.

          Powered tailgate no different to manuals regarding locking mechanism. They have been subject to a recall regarding strut failing.

                With the insignia if the alarm goes off and you dont have the indicators going with it, it could be the battery in the alarm thats flat and. I think i read the rear parking sensor ecu behind the bumper fills with water and sets it off as well as its on the same circuit.

                    Just checked with Vauxhall, all recalls up to date. They reckon it may be the battery in the power sounder. They want to book it in and run diagnostics first. Would opcom diagnose this issue?

                      I've read about this fault. The terminals corrode or something causing the alarm to go off due to failing battery back-up

                        TPMS module failure / water ingress leads to this as well, the only items on that LIN BUS are the power sounder and the TPMS module. If it fails it causes the sounder to go off and lights flash but no record of alarm being made. There was a technical service bulletin about the issue.

                        Do you have TPMS?
