The movement sensors inside have probably found a fly buzzing around.
Or you have left a window cracked and the wind has blown the seat belt.

I used to always disable my alarm on my RRC when I went camping as I would leave the windows down a bit for air circulation and forget to close them , only for the whole campsite to be woken.

On my D2 the PO had the alarm disabled so no problem.

Ok so next question how do you disable the alarm
thanks

You will need a nanocom or similar to be able to disable the function in the bcu

... or to lock the door with the key not the fob, that keeps the volumetric alarm disabled and all the rest active... the volumetric alarm detects air movement in the cabin so as said even a fly or moth trapped within or if it's windy and it's not sealed well or sunroof/window not closed well would trigger it

If you lock your car with ANY window open then the alarm will go off after a while.
put the windows ALL the way up.
Works on mine.

Mine does this with the windows up. It only happens on hot days though.

Just went off. Windows up, cool breeze, got me stuffed.

No little critters inside?...

Moth, fly anything like that?....the sensors in my D2's were very sensitive

It happened to my td5, first with windows left open an inch or two then when sleeping in the back first time i took it camping.
I will try an easy fix by sticking gaffer tape over the sensor above the LHS 'B' pillar.

Seems to go off when ever we lock it and leave it for about 15 mins. No rhyme or known reason.
