I have a BMW 525i whose alarm goes off on its own and flashes lights. This results in an annoying drained battery every time. The guys at the garage say it is the passenger side lock and actuator but i...

why not ask them to disconnect the lock actuator and leave the door panel off(to check alarm)if it does not go off, then you have not wasted you money,if it does, you can give the service manager some heavy grief...... but smile when you swear at him.

that is rarely the case actually, bmw's during the 2001 to 2004 models have a known alarm electronic issue.

Your problem is the cause of one or more of the following:

1. faulty hood enclosure sensor damaged from engine heat
2. interior motion sensor is faulty
3. the alarm sensor module
4. OR the sensitivity needs recalibration

None of these are cheap quick fixes, but taking your vehicle to a good mechanic is the first step.

Good luck with your issue.

97 bmw 528i factory alarm goes off for no reason

disable the hood microswitch. just unplug it. That and the cabin sensor are the most probably reasons the alarm will go off.
Alarms are useless. Totally effin useless. So it goes off.....then whaddya going to do. Shoot someone? Call the police? or listen to it drain the battery over and over again. can't disable the alarm totally. The bmw engineers have tied it into the main computer. you can however disable the sensors one by one so it doesn't set off the alarm. Hood sensor....Hood sensor....that's the culprit.
