Description
This Mercedes-Benz anti-theft alarm tilt sensor is a genuine OEM electronic component for the Mercedes W220 S-Class. Primary OEM number 2028203826. It is designed to detect any change in the inclination of the parked vehicle and report it to the alarm system, adding a layer of protection against towing away and theft of the wheels.
Its job is to measure the tilt angle of the car while the alarm is armed and send a signal to the control unit when the position changes beyond the set limit, which then triggers the horn and warning lights. A properly working tilt sensor supports reliable theft protection, prevents unnecessary false alarms, and ensures correct operation of the whole anti-theft alarm system of the vehicle.
Common signs of a faulty unit include random false alarms on a level surface, an alarm that does not sound when the car is lifted or tilted, a warning message about the anti-theft system or tilt protection, repeated alarm activation after parking on a slope, and fault codes stored in the alarm system memory. When the sensor stops working correctly, the vehicle may lose its tilt protection or trigger the alarm without a cause.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 2028203826 before ordering. Professional installation is recommended, and a diagnostic check or resetting of the alarm system may be required where applicable, so confirm the fitment details for your vehicle before you buy, as equipment versions differ between model years.
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.
