I'm going to throw this to all to see what comes back. I think I know what I'm going to need to do, but want to rule out all possibilities first.
The symptoms:
Random false alarms from alarm system. Using the reduced guard button had no effect ( I first presumed that it would be movement sensors).
I put my laptop on it today and the error message ( well, one of them! ) is Alarm Siren Missing.
So, I thought, OH no! Battery!. But I remembered that the first thing I did when I got the car 3 years ago was to replace the battery in the siren module.
Still, I went ahead, removed and opened up the siren and the new battery is in fine (physical) condition.
There is some marking on the tracks from when the previous battery failed, but these have not deteriorated further and look to be electrically ok.

Before I write off the siren, are there any other known issues which could cause this issue?
I seem to be getting a lot of issues one after the other at the moment....

Anybody selling a siren?
