Referring to my earlier reply and reading later posts- why the prevalence of 2.30 AM?

Hi all,

Had the car for 2 months with usual problems of 12 volt battery drain, warning lights etc etc.

I usually park the car under cover and the alarm has never gone off. Last night I parked in the open and the alarm went off at 10pm. It was heavy rain at the time. Reading through the posts it looks like rain could be one of the causes.

I read elsewhere there is a sensitivity setting that a dealer can modify, which defaults to 100% - I wonder if the workshops will turn this down a little as and when they see each car...

Had the alarm go off last night for the second time, first time the boot was not closed properly and the second time I had left the key outside my Faraday bag.

Not sure of they are related but will.keep any eye on it

I've had the car parked on the driveway all day without the alarm going off, but for the past 2 nights it gone off in the middle of the night - 2.30 and 4.40. Seems a strange coincidence that these alarms seem to be going off in the middle of the night...
Is there a way to lock the car without arming the alarm?

Mine has gone off 3 times over the last 2 days (11pm, 11:30am, 2am) even though it has the 0570 software which is supposed to mitigate the chance of it.

Each time I’ve checked the boot has been closed properly (which some have reported as the problem).

My car is back in the workshop the week after next, til then they’ve advised to disable interior monitoring and to let them know of it persists.

My alarm went off post upgrade to 0570 so I took it back in but they couldn't find any fault :( I asked them to upgrade to 2.0 but they didn't have the software :( :( and are only allowed to upgrade if they find a fault that the upgrade should fix. Didn't sound very helpful to me but I wasn't able to get any further.

Hi Guys, just joined this group with my new ID3. My alarm has gone off recently 1st time since delivery while in my secure garage, I checked the garage and content out to confirm all was in order. Nothing found but concerned it had gone off and repeated alarm sound till my attendance. Already becoming slightly disappointed in the ID3. Have had new golfs since their launch in circa 1979 in the UK, Today my ID3 reported a low 12v battery and stated the way to resolve is to drive it to change it!

So, the car was booked in at the dealers today to look at the 12V issue and the alarm going off. They found a dodgy connection at the 12V battery which they say has caused these issues. I'm extremely dubious about it being the case. I've asked for the software to be updated and they are saying "if there is any outstanding work/recalls they will act accordingly". Be interesting to see if they even bothered to update the software while they have it and if the fault they say they found will actually make a difference...

ID.3 in Sweden here. Three weeks old car and alarm has gone off three times whereas one during night (actually around 2:30 am...). And one in the evening and one during the day when we were all watching the spectacle go off without any exterior influences at all.

Dealer says alarm sensitivity is the problem and other owners has suffered from this too. Scheduled fix in a week from now.
Dealer (sales person) also says that a restart of the infotainment system could be something (I'm not sure how that actually does anything but that's what they said). Also, turning off the cabin sensor while parked could ease things but again, it's not really proven as I see it from their statements.
They also stated (repair person) that the software update does not do anything with the alarm in my case. My software version is an early one.
