Purpose and function of the parking sensor

The Mercedes W204 Parking Sensor PDC Distance Front operates in the front zone of the vehicle, monitoring the distance from obstacles during maneuvering. It works with the factory parking assistant system, sending a signal to the control unit, which generates acoustic or visual warnings. A properly functioning sensor helps reduce the risk of damage to the bumper and body components, and facilitates precise maneuvers in tight parking spaces.

Color matching and body aesthetics

The finish in the Polar White - 149 shade allows for seamless integration of the sensor into the painted surface of the bumper. As a result, the element does not disrupt the body lines and does not require additional painting after installation, provided the vehicle has the same color code. This is a beneficial solution for users who want to combine the functionality of the PDC system with maintaining a neat, factory look for the front of the car.

Installation characteristics and application

The presented sensor is designed for installation in the front part of the Mercedes W204 series, in the locations factory-designated for the PDC system. The design, based on the manufacturer's original solution, facilitates installation in existing bumper sockets and connection to the vehicle's electrical harness. The used component allows for an economical repair of the parking assistance system while maintaining compatibility with the factory installation architecture.

Product condition and benefits of choosing a used sensor

The item is offered as a used parking sensor, which represents a reasonable compromise between repair costs and maintaining the vehicle's original specifications. Choosing such a solution is particularly attractive when replacing a single sensor in an existing PDC system, provided the other components are working correctly. A used sensor allows you to restore system functionality without the need to invest in a complete new set.
