The car probably is not equipped with an alarm. on the 3 series the alarm is an option. The LED and all of the pre-wiring is there but the siren and a few other items are installed as a retrofit and then the Body module is reprogrammed to add the LED output and other alarm functions. Call your dealer for an install price or you can DIY however you will still need the dealer to code it for you after installing.
