The alarm on my id.3 has gone off four times. Last night was the worst - we were at a hotel and the alarm went off twice with no apparent reason - not a good advert for the car as the car park was close to all the rooms and woke many of the guests up. The other two times was at home but it is pretty poor that it happens at all.

Has anybody else suffered with this?

It’s happened to me three times too. Once over night at home and the other two times while it was parked on the street overnight.

There wasn’t anything happening around the car at the time except that one time there was heavy rain at the time.

This happened to me once. The boot lid wasn’t fully shut properly. The boot lid on my ID.3 needs a firm slam for it to fully latch closed.

Alarm has now gone off for no reason twice, last time at 2.40 AM. (Also in heavy rain?)
Emailed my dealer (also listing 6 other recurring glitches) - awaiting their reply

I would second hwhbev's comment about the boot lid. My car's alarm has gone off twice while parked on my drive. The second time I examined it carefully, and the boot lid was not closed absolutely tight, I could rattle it slightly. It was also raining hard. Perhaps a loose lid being hit by rain and wind triggered the alarm. I now slam the lid closed! If the alarm goes off again then my theory is blown. Time will tell, fingers crossed.

Hmmm... not sure. We’ve not opened our tailgate since last nights 2.40 am alarm call and it’s definitely fully latched. It’s in the garage tonight so we don’t wake the neighbours. Booked in with dealer (for a ‘few’ days) but not until November 9th - see what happens.

I also had the alarm sounding at random. Try using the start /stop button on the steering column before turning to N and pressing the park button. Works for me- famous last words!!!!!

Alarm went off again this morning - no rain, no wind, no beasties jumping on the car and the boot shut tight. It seems like on of those faults that will be hell to get fixed as it will never happen whilst the car is with the dealer! I'll try @metricman suggestion, thanks.

Hi folks,

My partner bought her ID.3 on the 31st October, and the last two nights we’ve had the alarm sound without any obvious cause. It’s parked roadside outside our flat. We’ll check out the boot closing and the pressing of the ignition button - thanks for the tips. Also going to talk to the dealer today if we can and see if they have ideas. Does anyone know if it’s possible to dig into the car’s software and see which of the sensors caused the alarm? Might help track down the issue...

All the best,

This happened to my ID.3 the night I took delivery at about 02:30 am. Not too popular with the neighbours. After some messing around I discovered I had left the second sent of key in the car. Once I removed them all seemed ok, and it hasn't happened since.
