My Alarm is driving me crazy and I have no idea what's causing it.
Hello everyone.
It's been a while I've posted on here, and of course I'm back with a problem. I just got a new car so I gave my 2000 323i to my mom. The car is flawless in every way, with the exception of the alarm that started going off for no reason. Sometimes it will go off the minute I lock the car, sometimes it will wait a few minutes, sometimes a few hours. Sometimes it goes off just once and that's it, sometimes it will just keep on going off. On one occasion, it even drained the battery, because the lights were flashing on and off in a period of 8 hours while I was at work. I kind of ignored it, by simply locking the car with the key instead of with the remote. I completely got used to it, until my mom started to use the keyless feature and started to call me back and forth complaining that the car goes off.
I can deal with all the mechanical and electrical issues on the car if they were to happen. This one however is beyond me and I have no idea where to look or what to test. I searched the net, I didn't really find the answers, just some people with similar issues.
If anyone, anyone please heard or has ideas before I drive it to dealership so they can welcome me with a $250 and up just by asking a question, I would soooo appreciate it, and so would my mom.

Thank you!
I had the same problem and eventually traced it to a faulty switch on the door, the computer thought the door was still open when it was shut, but intermittently, so the alarm would go off when it felt like it - usually at 2.00 in the morning when its cold out (its winter here in South Africa). I adjusted the travel of the strike in the door lock and the problem went away. Cost was zero.
There aren't really any adjustable components in the assembly next to the lock for the electric lock/unlock and the wiring is embedded into the plastic housing. Very elegant but no doubt expensive.
Jip, the winter here in Henley on Klip (GP) is the couse of the alarm going of on my BMW, found the left front door to be the culprit, she had to sleep outside as I am building a GT40, shes back indoors now and it looks like shes all good now, I think Isis is jealous...
