Alarm keeps going off

[Drew9]

My alarm went off at 11:30pm last night just as I was going to bed. I unlocked and locked via the fob through my bedroom window which seemed to fix it and went to sleep. Woke at 5am to it going off again. Did the same but it went off again, and again. I fear I’ve woken up my entire street. It’s now sitting on the driveway unlocked which is not ideal but is the only way to stop it going off. Any ideas? Is there anyway to find out what is causing it? Can’t take it anywhere as it’s Sunday.

A fly in the car would do it

Spray some fly killer in the car if you can't see one just in case. See if that fixes it.

Isolate the volumetric sensor in the car, as detailed in owner manual; as you would if you leave mutley in the car, whilst you're shopping [not in this heat though].

Had this happen just after buying our QQ. Went out and checked the car and reset it 3 times before spotting the rear parcel shelf wasn’t sitting properly so adjusted it. (The alarm didn’t go off after I adjusted the parcel shelf)
As daft as it sounds I could only put it down to the shelf ‘creeping/moving’ slightly and triggering the interior sensor
