I have a 2006 E85 Z4M and several times, in the Summer, when the car was parked on the road outside the alarm would persistently go off. Didn't seem to do it elsewhere. Now that the vehicle is away for Winter in the garage the alarm has behaved itself. Obviously a glitch somewhere.
I've owned the vehicle for some years, don't recollect previous problems. However, in searching this forum, there are mentions of the 'tilt' sensor and I'm wondering if the road camber is the culprit, it was resurfaced earlier this year. The garage floor is flat and level.
Any knowledge on this pls?

First one to check/goodle/search is bonnet alarm switch- simple to check or isolate?

Alarm problem
I left a car up on ramps for a few days and set the alarm over night. Didn't go off.Beemingallover wrote: ↑Mon Nov 15, 2021 12:51 pm I've owned the vehicle for some years, don't recollect previous problems.

But when I jacked the car, removed the ramps and lowered it down, the alarm went off as it got level.
Therefore I believe the tilt sensor detects a change from the position set when the alarm is armed, not anything away from horizontal. Otherwise how would people in hilly areas cope?
Having been woken by my alarm going off at 2am on Saturday morning, I disconnected the bonnet sensor and since then all has been good.
In your case possibly a bit of moisture that has since dried out. However, to be doubly safe you could disconnect it anyway?

Alarm problem
My alarm goes off for no reason. BMW says the brain is dead. I didn't want the BMW alarm in the first place, but my Viper alarm dealer could not get their alarm to work in my car. BMW wires the car strangely, so after 3 days of trying and discussing it with Viper corporate, they gave up. So I spent hundreds for a BMW alarm with 1/2 the features of a Viper and it's dead after only a few years. I have to hit the lock button repeatedly to disable the cabin sensors, or it goes off randomly.
