Purpose and function in the vehicle

The offered rear PDC sensor is designed for BMW Mini R55, R56, R57, R58, and R59 models equipped with the factory ultrasonic parking assistance system. The component is mounted in the rear of the vehicle body and is responsible for detecting obstacles behind the car, transmitting a signal to the control unit and the acoustic or visual system.

The ultrasonic operating principle ensures repeatable distance measurements, which translates into more controlled reversing, reduced risk of contact with walls, bollards, or other vehicles, and greater convenience in daily urban driving.

Reef Blue Metallic – B30 color and visual fitment

The sensor is finished in the Reef Blue Metallic – B30 shade, used as a factory standard in selected Mini vehicles. This ensures that the color consistency of the rear bumper is maintained after installation, without the need for additional painting or aesthetic compromises.

For Mini owners who prioritize maintaining the original appearance of the bodywork, using a sensor in the correct color reduces the time and cost of additional finishing work while allowing for the restoration of full parking system functionality.

Technical characteristics and installation

The rear PDC parking sensor is a component installed in the factory bumper socket, which allows for installation in the existing opening without interfering with the body structure. The design, intended for specific Mini generations, facilitates proper seating and connection to the vehicle's electrical harness.

In practice, the installation consists of:

• removing the damaged or faulty sensor from the rear bumper,
• seating the new component in the factory bracket,
• connecting the electrical wiring connector according to the original layout.

This solution promotes the maintenance of the correct sensor operating geometry and proper cooperation with the existing PDC controller.

Part condition and service application

The offered component is a salvaged part and is intended for users and workshops looking for a tested, original part to restore the operation of the parking system in a Mini. Replacing a single sensor is often sufficient to eliminate PDC errors and restore correct readings during reversing.

This type of solution is particularly beneficial for post-accident repairs of the rear body section or in situations where a single sensor has suffered mechanical damage or an electronic failure.

Integration with other elements and additional information

When planning repairs to the parking assistance system, it is also worth verifying the condition of the other sensors, the wiring harness, and the controller to avoid recurring faults. In the case of extensive upgrades or post-accident repairs, other salvaged components may also be helpful, especially if you want to maintain original OEM parts while keeping to a reasonable service budget.
