I can find no evidence of moths, cats or even foxes. Used the remote key-fob from inside the house to OPEN and it stops the alarm. How annoying!


Our car alarm goes off when our home charger deactivates. This has happended three times now at 5am. As a temporary fix I will set the charger to deactivate at 8am so at least we won't wake ourselves or the neighbours in the middle of the night. We will also try turning off the interior monitoring.

We've also had a couple of alarm activations overnight recently. I'm fairly sure that both were at 4.30am, which is when our charger deactivates. On both occasions it turned out that I hadn't closed the boot properly, but it does seem that the charger deactivation is triggering something.

Is it whilst you’re charging it? Or have ended a charge?

It's neither, it happens when the vehicle is parked.

I've had it only once, turned out to be the boot not being closed properly. Boot gets a firm closing since.

Hi. We have had our ID.3 Family for seven days now. Almost every day the alarm has gone off at random. And twice in the middle of the night. It is parked on the street in front of our building. Whilst I thought this might be connected to the start of heavy rains (not good, but sort of explicable), the latest incident has occurred on a dry afternoon. The boot and the doors are closed/locked properly. Do I need to take the car to a VW dealer, or is there a simple solution I can make myself? From the various messages on this thread, it's not clear to me what self-help options I may have.

I’d take it to the dealer. On the off chance do you have anything plugged into the OBD socket or any of the USBs?

(If I leave my OBD dongle plugged in it often sets off the alarm).

On the goodbye screen, when you've set it to Neutral/Park, one of the settings (the bottom one) is 'interior monitoring' - disable that.
When disabled, the alarm isn't checking inside the car when you lock it. Leave if disabled overnight or preferably longer...
  • If the alarm doesn't go off, it is something inside the car that is triggering the alarm - or a faulty interior sensor
  • If the alarm continues to go off, it's nothing to do with the interior of the car and is something to do with an external sensor (possibly faulty)

The only time this has happened to us it was because the boot was not properly closed, and the alarm triggered when charging started. Until then I didn't know it had an alarm, so annoying but educational.

Thank you MotMot, David and Steve. We have disabled the Interior Monitor since last evening and (fingers crossed), the alarm hasn't activated since then. That seems to be working.

Hi All,

I have an id 5 and last night the alarm went off 2 times and same as everyone else there was no reason for that alarm to go off so I contacted Volkswagon Roadside Assistance and they did a diagnostic and said a software needs to be updated alongside a control module as it is having issues communicating with the car ... the same was also said by the on site expert..... my car has gone into the dealership for this let's see.

Have similar problem in last couple of days when charging by solar and clouds interrupt charging, but also last night at 1 am when charging started. OK once I unlocked and relocked car. Will check boot is fully closed. Not had this problem in the past, car is 2 years old and going for service and s/w update in a couple of weeks. False alarms in the past due to dashcam falling off windscreen triggering internal monitor, now cured using sticky pad to secure dashcam.
