Purpose and Function of the ESP Module

The presented ESP module with sensor is an electronic component responsible for collecting vehicle movement data and transmitting it to the stability system controller. In practice, this means control over phenomena such as wheel slip, oversteer, or understeer, as well as support for the braking and drivetrain systems in emergency situations. Its placement at the rear of the vehicle ensures accurate representation of the body's behavior and allows the ESP system to react predictably and repeatably.

Construction and Vehicle Integration

The ESP module with sensor has been designed as a component that works with the factory electrical architecture of Mercedes vehicles. The design anticipates installation at a specific point in the rear of the body, which facilitates correct positioning and reduces the risk of installation errors. The connectors used are adapted to the original wiring harness, ensuring consistency with other safety system modules.

This component belongs to the Other category, which in practice means it performs a specialized function within the vehicle's electronic systems, and its selection should be based on compatibility with the specific model version of the C-Class or CLK.

Vehicle Placement and Installation Aspects

The offered ESP sensor module is intended for installation in the rear of the vehicle. This placement allows for:

• accurate representation of body movements in the longitudinal and lateral axes,
• stable ESP system operation under varying rear axle loads,
• proper cooperation with other safety system sensors.

When replacing, it is recommended to maintain the factory installation position and check mounting points to ensure correct sensor orientation relative to the body. A properly installed module supports consistent ESP system calibration and reduces the risk of diagnostic errors.

Used Product Characteristics

The presented ESP sensor module is a component in used condition, which is a cost-effective solution for users seeking original components at a reasonable price. A used part allows for compliance with the vehicle's factory specifications while reducing the cost of repairing the stability control system. Choosing such a solution is particularly attractive for older generations of the C-Class and CLK, where maintaining the functionality of safety systems within a rational service budget is a priority.

Part Selection and Compatibility

The module has an assigned OEM part number and corresponding interchangeable numbers, which facilitates verification of compatibility with a specific vehicle version. Before purchasing, it is advisable to compare the markings with the data from the removed component or service documentation to ensure full compatibility with the vehicle's electrical system and software. This allows the module to be integrated into the existing controller network without requiring installation modifications.
