Purpose and function in the vehicle

The presented radar sensor is designed for installation in the rear part of the vehicle body, with the possibility of installation on both the left and right sides. Thanks to this, it can cover the zone behind the vehicle in a wide range, working with the factory driver assistance systems in Mercedes C238 series models.

This component is responsible for detecting objects located behind the car, which is important, among other things, when maneuvering, changing lanes, or maintaining a safe distance. As part of the electronic system, the sensor transmits data to the master controllers, which then take appropriate actions to assist the driver based on this information.

Construction and technical characteristics

The radar sensor belongs to the Electronic control modules and controllers group, which means it is an integral part of the vehicle's electronic architecture. It has been developed by the manufacturer for stable operation in variable road conditions, such as moisture, temperature fluctuations, or contamination typical for the rear bumper zone.

The intended location on the vehicle is at the rear, with the possibility of mounting on both sides, which facilitates matching to a specific factory configuration. The module's construction is prepared for cooperation with the original electrical harness and factory mounting brackets, which helps maintain the correct operating geometry of the radar.

Integration with Mercedes systems

As a Mercedes brand product, the sensor is intended for integration with the brand's factory safety and comfort systems. Proper matching to the vehicle's electronic architecture allows for:

• maintaining communication consistency within the controller network,
• proper cooperation with driver assistance systems,
• minimizing the risk of errors resulting from incompatible replacements.

A used OEM component of this type is often chosen for repairs where it is crucial to maintain the original logic of the assistance systems, without interfering with software or making additional modifications to the installation.

Condition and service application

The offered module is in used condition, which makes it an attractive solution for post-accident repairs, replacing damaged sensors, or restoring full functionality of assistance systems in older cars. In many cases, using original used electronics allows for a favorable compromise between repair costs and maintaining factory operating parameters.

Before installation, it is recommended to verify compatibility with the specific vehicle equipment version and to perform adaptation or calibration as part of the service procedures provided by the manufacturer, so that the radar sensor works fully correctly in the given car.
