Hi, recently my Octavia has been causing grief when trying to lock it. Often after about 30 seconds to a minute the alarm will go off (sometimes just the indicators start flashing but with no alarm sound). I can normally, but not always, tell the alarm is going to go off because the little red indicator light either stays lit solid after I lock the car, or it doesn't light up at all, instead of the usual regular flashing it used to do before this issue started. So far the only solution I've found is to keep unlocking and locking it again until the alarm doesn't come back on.
The dash lights for open doors/boot/bonnet all work when they are open, so I can tell everything is closed and presumably there are no issues with the door sensors? I've read on another forum that the alarm can start playing up if the battery is dying, but I've checked it and it keeps a good 12.3v so I assume that's not the issue? I've also tried pressing the button on the door pillar to disable the internal motion sensors but that hasn't made any difference. Does anyone have any other suggestions?
