Alarm

When opening my trunk with the key in my pocket, my car alarm will occasionally go off. I can't seem to track this to any particular action on my part, just random. Anyone else having this issue?

I'm having the same issue. It started happening after my dealership upgraded software.

It seems to be related to the timing of opening the trunk. It happens randomly when I open my trunk right after approaching my car. However, if I approach my car and stand for 3 seconds in front of my trunk and then open the trunk, it will not happen.

This issue is very annoying...

Probably corrected in newer version of ISTA. Take car in and have it reprogrammed.

I am experiencing the same problem. Very annoying and embarrassing if it happens when others are nearby. The Dealer says he has not heard of the problem before and doesn’t have a solution. Not bothering me too much so I am just putting up with it for now.

That sounds irritating. Thankfully I haven't had that problem, even though I frequently go straight to the back of the car and open the boot (trunk) without unlocking the doors

Just a thought.. is yours set to unlock when you approach? I disabled that because it was getting tedious.

I spoke too soon.

I opened the boot/trunk this morning and off went the alarm. Bizarre, because I didn't do anything different from what I normally do.

Alarm retrofit

I received my 2020 Z4 without the Alarm option, is there a possibility to install a third party one? The dealership is not helping much and not answering about the retrofit option .
Please advise

Same here, alarm went off when opening trunk with keyfob in pocket.
Kind of embarassing loading groceries in the parking lot of the supermarket.

Tested again yesterday, was ok..

Mine has done it 2 times in the 20 months I've had the car. Hasn't done it since I did the software upgrade last week, but I wouldn't expect it to with low rate of occurrence I've had.
