Purpose and compatibility

The ultrasonic sensor set has been designed for BMW E81, E82, E87, E88, E90, and E91 series models equipped with a front PDC system. The sensors are mounted in the front body area, working in conjunction with the factory electrical installation and parking control unit. By maintaining the original geometry and operating characteristics, the system retains its proper sensitivity and predictable performance when maneuvering in tight spaces.

Technical specifications of the set

The set includes four ultrasonic sensors in a uniform Sydney Blue color, intended for installation in the front bumper. The design is based on the factory BMW solution, which facilitates integration with existing brackets and wiring harnesses. The ultrasonic technology used enables precise obstacle detection within the typical operating range of PDC systems, providing the driver with clear acoustic and visual signals (depending on vehicle configuration).

Condition and functional properties

The set comes from the secondary market, allowing for an economical replacement of components while maintaining original BMW specifications. The sensors are intended for reinstallation in place of the factory sensors, without the need for any wiring modifications. The uniform Sydney Blue color reduces the need for additional painting if it matches the body color, and in other configurations, it can serve as a base for further paintwork.

Benefits of using original PDC sensors

Using factory ultrasonic sensors in the PDC system translates into stable system operation and predictable warning signals. For the user, this means:

• maintaining proper cooperation with the factory parking control unit,
• consistent performance of all sensors in the set,
• aesthetic match to the front bodywork thanks to the blue finish,
• the ability to restore full system functionality after the failure of individual sensors.
