Purpose and function of the sensor

The presented parking sensor is a PDC system component responsible for precise distance measurement in the front part of the vehicle. Mounted in the bumper, it works with the factory electrical installation and the parking assistant controller, generating audible and visual signals that facilitate maneuvering in tight spaces.

Thanks to its dedicated placement on the vehicle, the sensor operates within an optimal range, which translates into stable performance of the parking assistance system and reduces the risk of body damage during low-speed maneuvers.

Color and visual fitment

The finish in the Alabandine Grey Metallic - 779 shade allows for seamless integration of the sensor into the bumper paint, without the need for additional painting while maintaining color consistency with the factory palette. This solution is particularly beneficial for post-accident repairs or when replacing a single element in an already painted bumper.

Selecting the correct sensor color minimizes visual differences between the component and its surroundings, which is important both from an aesthetic point of view and for maintaining the vehicle's value after repair.

Technical characteristics and installation

The sensor has been designed as a component intended for operation in the front part of the car, taking into account the specific operating conditions in this area (exposure to dirt, water, and temperature changes). The construction is prepared for integration with the factory PDC system, which facilitates connection with the existing wiring harness and controller.

The item comes from a group of used components, which means it has been previously used but is still suitable for further operation in the parking assistance system. This type of component is a good choice for vehicle servicing where maintaining the original system specification is key.

Application of a used PDC sensor

Choosing a used parking sensor is justified both economically and technically – it allows for maintaining the factory system configuration while reducing repair costs. A properly selected element from this group ensures compatibility with the vehicle's installation and the preservation of parking assistant functionality.
