Purpose and function of the PDC sensor

The PDC sensor is responsible for real-time distance measurement from obstacles while maneuvering the vehicle. In this variant, it is adapted for use in both the front and rear zones, allowing for flexible application depending on the bumper configuration of a given BMW E87 or E90 series model. A properly functioning sensor supports the driver with acoustic and visual signals, facilitating parking in tight spaces and reducing the risk of minor body damage.

Color and visual fit

The Jerezschwarz Metallic - A73 finish is characteristic of dark, metallic BMW paints, allowing the sensor to blend harmoniously into the bumper line. This color choice maintains the stylistic consistency of the bodywork without the need for additional painting of the component. This solution is particularly beneficial when replacing a single sensor in an already painted bumper.

Integration with the BMW system

As a BMW group component, the sensor is structurally prepared to work with the factory wiring and PDC control modules in E87 and E90 models. The precisely selected housing geometry facilitates seating in the bumper socket, and the correct operating parameters ensure the parking system remains properly calibrated. As a result, installation is limited to mechanical mounting and connection to the existing harness, with no need for system modifications.

Application in service practice

The presented sensor is suitable both for the spot replacement of a damaged component and for broader work related to bumper repair after a collision or parking system upgrades. Using this component allows for the cost-effective restoration of full PDC system functionality while maintaining compliance with factory BMW standards. It is a practical solution for workshops specializing in the brand and for users who wish to maintain the original equipment configuration.
