Original BMW Alarm Siren with Tilt Sensor for BMW 1 Series, 3 Series, 5 Series, 7 Series, X1, X5, and X6 (2002–2015)

The Original BMW alarm siren with tilt sensor is the sounder for the factory anti-theft alarm on BMW 1 Series, 3 Series, 5 Series, 7 Series, X1, X5, and X6 models from 2002 to 2015. BMW calls it the alternate-power siren with inclination indicator. That name points to two features. BMW designates the unit as an alternate-power siren, and it has a sensor that reacts to a change in the car's angle. When the alarm is triggered, the siren gives a loud, distinctive tone to alert people nearby and discourage a thief. BMW started production of this version in October 2010, and the unit is made in Italy.

Original BMW Parts carry a 24-month parts warranty.

This number supersedes siren 65-75-9-223-072, and BMW rates the change as exchangeable retrospectively. The current siren can therefore replace the earlier part on cars built before October 2010, which covers many of the 2002–2010 models in this range. Several older numbers also cross-reference to this siren, including 65-75-9-189-818, 65-75-9-167-637, 65-75-9-124-581, 65-75-9-117-900, 65-75-6-948-392, and 65-75-0-393-079. If the siren on your car carries one of those numbers, this is its current replacement.
