Purpose and function in the vehicle

The presented item is a rear PDC sensor designed for Audi A4 and S4 B7 generation models. Mounted in the rear bumper, it works with the vehicle's factory installation, assisting the driver when maneuvering in tight parking spaces, underground garages, or reversing in confined areas. A properly selected sensor allows for maintaining the full functionality of the obstacle warning system, minimizing the risk of body damage.

Color and visual fit

The sensor is finished in the Light Silver Metallic - Y7W shade, which allows for aesthetic integration into a bumper painted with the same paint code. As a result, the element does not visually stand out from the body surface, and the bumper line remains consistent. This is particularly important for post-accident repairs and when replacing a single sensor, where maintaining the vehicle's factory appearance without the need for additional painting is desired.

Technical characteristics and installation

As an original Audi component, the sensor is adapted to work within the factory PDC system, maintaining appropriate sensitivity parameters and distance measurement characteristics. Its rear placement on the vehicle ensures proper cooperation with other system components, such as the wiring harness and the parking system control unit. In practice, this translates into:

• correct obstacle detection in the rear zone of the vehicle,
• consistent operation with other sensors in the bumper,
• preservation of the factory acoustic and visual signaling logic.

Thanks to its OEM-compliant design, installation usually comes down to seating the sensor in the bumper socket and connecting it to the existing harness, without the need for installation modifications.

Condition and service application

The offered item is in used condition, making it an attractive solution for an economical repair of the parking system in an Audi. Such components are frequently used in workshops specializing in automotive electronics and in body and paint shops, where both correct operation and visual matching to the body paint are important. Choosing an original sensor from the secondary market allows for cost reduction while maintaining compatibility with the car's factory equipment.
