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.
