Description
This Mercedes Bosch crash sensor is a genuine OEM safety component for the Mercedes W124, W126, W201 and R107 models. Primary OEM number 0003820610. It is designed to detect the sudden deceleration of a frontal impact and to send the trigger signal to the airbag and restraint system, so that the protection devices can be deployed at the right moment.
Its job is to measure the deceleration of the vehicle during an impact and to report it to the airbag control unit, which then decides whether the airbag or belt tensioners must be fired. A properly working Bosch crash sensor supports correct deployment of the restraint system, reliable occupant protection and correct operation of the safety circuit on these classic Mercedes models.
Common signs of a faulty unit include a lit airbag or SRS warning light, a restraint system that reports a sensor or wiring fault, a warning that stays on after the system self-test, or stored fault codes for the impact sensor circuit. When the sensor fails, the restraint system may be disabled by the control unit or may not react correctly in a collision, which is a serious safety risk.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 0003820610 before ordering and compare it with the number on the label of your unit. Professional installation is recommended, and a diagnostic scan of the restraint system, careful handling of all airbag components and a fault memory reset where applicable should follow installation.
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.
