You don't have the full version of the alarm system. The light on the rear
view mirror only blinks when you have the additional stuff installed.
Yes, it is prewired (meaning that all you need to do is plug the module into
the wiring harness). However, you don't get the audible alarm (including
Thanks for the info. So how would I connect the module to the wiring
harness? Is there a way to test to see if the alarm is active?
I did buy it used...but it's hard to beleive that a car that originally
listed for $42K doesnt come standard with an alarm system....
Installing the alarm is a simple enough DIY, but you'll probably
have to get it activated by the dealer once you install it:
However, the usefulness of the alarm is questionable. The only things
it'll probably protect against are (maybe) wheel theft, (maybe) stereo
theft, and (maybe) preventing your car from being stolen via tow truck.
It won't protect against a smash-and-grab, and the existing security
features prevent the car from being hotwired. Even without the alarm,
to steal the car, a thief will have to (1) tow the car, (2) social
engineer a dealer into having a duplicate key made (which supposedly
requires ID and registration, although these can be forged), or (3)
stick a gun in your face (there are other rumors about ripping out and
replacing the car's computer, but I don't know how credible this is).
[ And, for $DIETY's sake, if you get the alarm installed, don't have the
alarm programmed to deactivate if the driver's door is unlocked. If
enabled, that's one of the easiest ways for a thief to disable the
Thank you for all of the information, I really appreciate it.
As for me, I live and work in downtown Atlanta...so security is
somewhat of a concern....Really all I want is some sort of theft
deterrant like I had on my ...err....hondas.....meaning an alarm sounds
if someone tries to break a window or open a door without a key
Do they not have car theft in germany? Is this a burden of capitalism?
Well, the cheapest way to get the alarm is to install it yourself
(IIRC, I think the cost is around $250-$300 for the kit) and then pay
the dealer to activate it.
Alternatively, if your car supports it, you could just pay the
dealer to have the red "alarm clown nose light" (under the mirror)
activate when you lock the car (basically, a fake alarm light). I don't
know if you can do that on a 2002, although it's possible on newer
Oh, they do have BMW car theft in Germany. I'd guess that it's an
even bigger problem over there, as there's a demand for BMW cars/parts
in the former USSR. The European car theft gangs certainly seem more
organized (and, rumor has it, much more capable). My guess is that an
alarm wouldn't slow them down much.
Thank you for the detailed replies. All is helpful information.
The fact that the car is immobilized without a key is helpful -- it
addresses my first concern. My second concern is that I wouldnt want
anyone to break in the car and vandalize it...or even sit in it
;)......so if i got the red light activated, that would be a good
I don't know if Atlanta is like Los Angeles, but here, except for
being annoyed, no one pays any attention to car alarm sounds. In
fact, I'm in favor of laws to ban car alarms. The standard BMW
security system is very good. When I bought my car, I asked how much
discount I'd get to install an alarm. The answer was no discount.
That tells me how much the insurance company values an additional
alarm system. I don't have an alarm in any of my cars, and one car is
To me, the major value of the alarm is:
1. It's really likely to wake me up if tripped, since the driveway is
outside my bedroom window. Given that a 330i was stolen in our
neighborhood last year by being towed away at night, this is good enough
for me. (At work there are security cameras and virtually no theft. In
fact, most people don't even lock their cars there.)
2. It provides an audible indication that the doors and trunk are all
I don't expect any beneficial effects whatever beyond those two.

'tis true, though. The alarm is an extra-cost accessory. There are
three things to be plugged in. The alarm itself, the motion sensor, and
the tilt sensor. They all plug in to the existing wiring. The alarm
goes under the microfilter housing, the motion sensor in the middle of
the headliner under the cover made for it, and the tilt sensor goes
behind the trim to the right of the battery in the trunk.
The easy way to see whether the alarm is installed: Get in the car and
lock it with the remote. Wait 20 seconds. Wave your arms around. If
it's still quiet, you don't have one. Or, take the cover off the
headliner. No motion detector, no alarm.
