Purpose and function of the PDC sensor

The presented sensor is a component of the rear parking system in the BMW 7 Series E65. It is responsible for accurate distance measurement from obstacles and transmitting the signal to the PDC control unit, which generates acoustic or visual warnings for the driver. Installation in the rear of the vehicle increases maneuvering safety while reversing, reducing the risk of damage to the bumper and body components.

The silver color of the housing makes it easy to match the factory paint of many BMW E65 configurations, allowing for a consistent bumper appearance without the need for additional painting.

Construction, color, and body integration

The sensor features a compact design adapted for mounting in the rear bumper socket. The silver finish of the housing provides a neutral, subtle look that blends well with typical paint shades used on the BMW E65. As a result, the component remains visually discreet after installation, and the bumper retains its factory character.

Placement in the rear of the vehicle allows for optimal coverage of the reversing zone, and the properly selected sensor geometry supports stable operation of the PDC system under typical operating conditions.

Compatibility and identification parameters

The sensor is part of the original BMW equipment line, which translates into proper fitment with the electrical installation and control units used in the E65 series. The component has a dedicated OEM part number and interchangeable numbers, which facilitates verification of compatibility with a specific vehicle configuration in parts catalogs.

Thanks to this solution, it is possible to restore full functionality of the parking system in a controlled manner, without the need for substitutes that require wiring modifications or programming.

Condition, service application, and installation

The offered sensor is a used component, intended primarily for service applications, such as replacing a damaged sensor in an existing PDC system. In practice, this means the possibility of an economical repair of the parking system while maintaining the original BMW specification.

Due to its factory design for the rear of the vehicle, installation takes place in the location provided by the manufacturer, which helps maintain the correct distance measurement geometry. It is recommended that the installation be performed by a workshop experienced with BMW electronics to ensure proper seating in the bumper and correct connection to the wiring harness.
