Purpose and function of the door impact sensor

The door impact sensor in the BMW 1 Series F40 operates in the side area of the body, where it is responsible for recording sudden acceleration changes in the door region. It is a component that contributes to the logic of passive safety systems, which is why its proper operation is crucial for the correct response of protective systems in a collision situation.

As a component from the Doors and door panels category, the sensor is integrated with the door structure or its immediate surroundings, which requires proper matching in terms of shape, mounting points, and electrical connector. Using an original BMW solution reduces the risk of installation errors and software compatibility issues with control units.

Benefits of using an original BMW component

Choosing an original door impact sensor for the BMW 1 Series F40 ensures:

• consistency with the vehicle's factory electrical and electronic architecture,
• proper cooperation with control modules responsible for safety,
• appropriate activation threshold parameters, in accordance with the manufacturer's specifications,
