Description
This BMW DWA alarm inclination tilt sensor is a genuine OEM alarm component for BMW E46 and E39 models. Primary OEM number 8386932. It is designed to track the attitude of the car while the anti-theft system is armed and to report a sudden change of angle to the DWA alarm, so that jacking, tilting or towing the car away does not go unnoticed. It works together with the other sensors and the control unit of the same alarm system.
Its job is to sense the inclination of the car body and notify the alarm control unit when it changes beyond the stored threshold, such as when a wheel is removed with a jack or the car is lifted onto a trailer. A properly working tilt sensor supports full theft protection, correct arming behavior and correct operation of the factory DWA alarm system with no unwanted alarms.
Common signs of a faulty unit include an alarm that sounds for no reason, false triggering when parked on a slope or in heavy wind, no alarm response when the car is raised, and a DWA fault indication after the car is locked. When the sensor fails, the alarm system may trigger randomly or ignore tilt events, which can drain the battery and leave the car less protected against theft. Replacing it restores quiet, dependable alarm operation.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 8386932 before ordering. Professional installation is recommended, and alarm system reset or adaptation may be needed where applicable. Test the alarm after fitting to confirm that it arms and disarms normally.
