I looked at disabling the interior monitoring sustem but understand it reactivates when the car is locked again

I was advised by dealer to do this temporarily before it went into the workshop, you have to do it each time you leave the car on the "Goodbye" menu.

Sty-evs thank you for your comments. Unfortunately it is key less but the fob etc is stored in an Rfid wallett away from the car. I have a conference call with local dealer management tomorrow and will raise the sensitivity issue. I looked at disabling the interior monitoring sustem but understand it reactivates when the car is locked again! Not sure if anyone from VW Germany is fully investigating the problem as it does appear to be a common fault.
Just a thought – might it be electromagnetic interference? Do you live near pylons, mobile phone mast, navigation radar, electric fence, amateur radio aerial, etc? Does the alarm get triggered just as often if you park elsewhere?

No known interference as you suggest and no problems with my Tiguan or neighbours VW!

My ID3 Family has been at the dealership for over 2 weeks and they have finally given up trying to fix the alarm issue. They have just told me VW have promised a fix is being developed but they can't say when.

The dealer has offered to leave the courtesy car with me but for how long ?
I am minded to try and return the car completely and get my money back but I suspect I don't have the stomach for that fight.

After several months with no alarm issues, it has gone off twice in the last three nights - at around 05:00 :evil:

But looking back over this thread, it seems that there is no fix in sight... :(

My id3 alarm went off after using it for 3 weeks. The software was updated to 0792. Anyone knows what is the latest software upgrade? Any fix by dealership so far?

I had a similar problem and found it was related to the boot catch although it shut ok there was a plastic bag handle slightly caught in the catch. I also noticed that the ‘random’ alarms were also occurring consistently every ~190 mins soo I suspect there is a reset timer in the software code somewhere. So try closing the boot more firmly and check for any minor obstructions in the catch.

I had a problem with the alarm on my id3 going off at random although invariably in the middle of the night - 9 times. The dealer investigated and found it was a fault with the incline (or inclination) sensor. The sensor was replaced and the problem seems to have been fixed. Car only 7 months old and it's the second time it's been in for repair.

My id3 alarm has started going off at random. Happened today while driving. No warning lights or messages on the screen, just a loud continuous horn sound. Anyone know how to stop it??

The alarm on mine sometimes goes off when I get close to the car. Its happened 3 times over the last 3 months of so.
