Vehicle Application and Placement

The presented sensor is dedicated for installation on the rear axle, with the possibility of use on both the left and right sides. This solution facilitates part selection in the service center and allows for flexible replacement depending on the side of the vehicle where the fault occurred. The sensor's design is adapted to the geometry of the hub and steering knuckle in Mercedes W169 and W245 platforms, which translates to secure seating and proper cooperation with the pulse ring.

Technical and Functional Characteristics

As an element of the ABS Speed Sensor category, the product is responsible for precise measurement of wheel rotational speed and transmitting the signal to the braking system controller. A stable signal from the sensor is crucial for:

• correct ABS operation during sudden braking,
• support for stability control systems,
• maintaining proper functionality of traction control systems.

Original Mercedes origin means adherence to proper electrical and mechanical parameters, which minimizes the risk of controller errors and accidental illumination of ABS or ESP warning lights on the dashboard.

Application of a Used OEM Sensor

A used speed sensor from original Mercedes production is a solution that allows for combining rational repair costs with maintaining the factory specifications of the braking system. Compared to low-quality aftermarket alternatives, an OEM part usually cooperates better with the vehicle's electrical system, and its mounting geometry complies with the manufacturer's requirements. This is particularly important for sensors installed in the demanding environment of the rear axle, exposed to dirt, moisture, and temperature changes.

An additional advantage is the ability to match parts by OEM number and interchangeable numbers, which facilitates the identification of compatible sensor versions within the same model family. This allows the service center to select the correct part faster without the need for installation modifications.

Support for Selection and Operation

When replacing an ABS sensor, it is worth paying attention to the condition of the mounting socket, cable, and electrical connector to avoid the recurrence of errors in the braking system. Proper installation, cleaning of the mating surfaces, and inspection of the signal cable allow for full utilization of the original part's potential and restoration of correct safety system operation.
