How much dust or dirt has built up inside the units? If they have become dirty, they will randomly go off also. Get a bottle of canned air like you would use to clean off a computer and use that to blow the smoke detectors clean inside. If they still go off, make sure you are using a good quality battery. Some smoke alarms do not like the generic, cheap batteries.
To find out if there are faults related to your complaint then the car has to be connected to either a BMW GT1 or Isis diagnostic machine (assuming that your car has a factory installed anti-theft/alarm system). But usually it is the front hood position switch that causes undue alarms. If you want to replace it without a proper diagnosis then it is a cheap and easy repair. The switch is near the right side strut tower inside the engine compartment near the battery jumper points. But remember that there are other possible causes of your complaint. The tilt sensor or even the ultrasonic alarm module are some of the possibilities. But to find out you have to pay for diagnosis with either a dealer or an independent BMW shop.
