W169 How to disable and find malfunctioning alarm?

[JITR]

When the alarm lapses into "sounding off" mode, which is not every day, the lights flash or the alarm goes off at random. The key fob stops this but not for long. It usually happens while the car (A180 CDI 2005) is parked. Makes no difference whether the doors are locked or not.

Does anyone know:
1. How to disable the alarm (e.g. by removing the fuse and allowing the battery in the alarm unit to run down)?
2. Where the alarm unit is located?

Many thanks.

Try Googling Bert Rowe's A class info. This website has almost everything you might want to know about old A class motors, great index on it so you can find what you need. My local garage consults it as I discovered when I took mine in

Thank you Smart320. Yes, a great index and many references to alarms. Not sure they answer my questions but I will check them again. The good news is the alarm has not gone off again since I asked.
