Description
This BMW DWA interior movement sensor is a genuine OEM electronic component for the BMW E39 5 Series. Primary OEM number 8376993. It is designed to monitor the passenger compartment of the parked and armed car and detect any movement inside, for example when a window is broken or someone enters, and to report it to the DWA anti-theft alarm system. It is a small sensor unit that is part of the factory anti-theft equipment of this model.
Its job is to scan the interior of the vehicle, usually with ultrasonic waves, and to send a signal to the alarm control unit when the pattern in the cabin changes. A properly working interior movement sensor supports reliable theft protection, avoids false alarms caused by normal conditions and supports correct operation of the whole alarm system of the car, including the horn, the hazard lights and the alarm indicator.
Common signs of a faulty unit include false alarms without any reason, an alarm that does not react to movement inside the car, alarm system warnings or fault entries, and an alarm that cannot be armed correctly. When the sensor fails, the DWA system may trigger at random, may stay silent during a real break-in or may drain the battery by repeated alarm cycles, which is annoying and can leave the car without interior protection.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 8376993 before ordering. Professional installation is recommended, and coding or adaptation of the alarm system may be required where applicable.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
