...if it's not on a trickle charger then battery might be running low and triggering it?

I leave mine on a CTEK...

Low battery usually triggers alarms.

Check you have not left the centre armrest up, double beep is something left open

As above either an open compartment.. arm rest, glove box, frunk or battery low which sets off alarm. You will know if it is the battery as you won’t be able to start the car. Had that problem recently.

Must be that time of year, my alarms started going off randomly atm. It started doing the double beep which would indicate something left open, so I opened/closed everything - doors, bonnet, boot, glove box & central arm rest cubby hole. I thought that had fixed it, as it stopped the double beep, but the alarm still keeps going off randomly. Usually at night though I have to say.

How ive fixed it atm is to press the lock button twice on the key fob, which apparently turns off the internal sensors - so motion, glove box & cubby hole. Fingers crossed its not gone off since, which would indicate some sort of fault with one of those 3 sensors.

Im not sure how I can narrow it down as there are no faults showing in the logs when I check with durametrics.

Ok .. the first thing to check is whats actually triggering the alarm ..

i would use a tester and look at alarm activations and events .. this will actually tell me what has been faulty when the car was locked and what actually triggered the alarm .

I can also see the positions of every item of the alarm system and see whats faulty .

Basically if you dont have a tester then i would guess at a half hour labour charge to you at an Indy .

This is obviously far cheaper than throwing bits at it in an attempt to fix the fault .

Strangely enough .. it may well be the siren thats causeing this !

What is single beep? Mine does this on locking and then at some random interval afterwards the alarm will go off. To stop this I lock then unlock the car, don't open a door and it locks itself after 60 secs and the alarm stays silent.

I think a single beep is something left open (or a sensor thinks its open) and a double beep is a fault in the system?

Thanks Infra - I was confused by the information that a double beep was something left open. Single beep something left open (which of course it isn't so it is a faulty microswitch I expect).

I have had similar issues in the past with my 996.

I've noticed on my car there are two sources of a 'beep'.

The car horn will beep if something is left open, or if I double click to lock and disable the internal sensors.

But sometimes the alarm siren will beep one or twice when locking, apparently randomly and I have yet to find a reason/documentation for these beeps.

Just wondered which 'Beep' the OP is hearing. Horn or Siren?

i t was both,first the horn then the siren, followed by the siren going off in full effect a few seconds later. All seems to be fine now with the smart charger on after a week of charging i shall plug the siren back in and see if it goes off, results to follow. Thumb
