Purpose and function in the vehicle

The presented PDC sensor is designed for installation in the rear area of the vehicle, where it is responsible for continuous distance measurement from obstacles while reversing. As an element of the parking assistance system, it works with the vehicle's electronics, generating acoustic or visual signals that facilitate safe maneuvering in tight spaces. Its placement in the rear bumper means the component operates in demanding conditions – it is exposed to water, dirt, and temperature changes, which is why using an original Audi solution is important for the stability of the entire system.

Color and body integration

The sensor is finished in the Brilliant Black Metallic – Y9B shade, which allows for an aesthetic match to factory-painted Audi bumpers in this color. As a result, after installation, the element does not visually stand out from the bumper surface, and the body line remains consistent. This is particularly important in premium class vehicles, where finishing details affect the overall perception of the car. Using the correct color variant also reduces the need for additional painting after installation.

Compatibility with Audi models

The offered parking sensor is dedicated to selected versions of Audi A4, A5, and Q7 models equipped with a PDC system in the rear of the vehicle. As an original Audi component, it ensures compatibility with the factory electrical harness and bumper construction, which facilitates installation and minimizes the risk of communication issues with control modules. In practice, this means the ability to restore the correct operation of the parking assistant without the need for installation modifications.

Characteristics of the used part

The component comes from disassembly, which allows for an economical restoration of the parking system's functions while maintaining the original Audi specification. A used PDC sensor is a good choice in situations where a single sensor has been damaged as a result of a collision, hitting an obstacle, or bodywork and paint repairs in the rear part of the vehicle. Replacing a single element is usually less time-consuming and more cost-effective than a complete system overhaul.
