Purpose and function in the vehicle

The presented sensor is designed for installation in the front part of the body, where it is responsible for continuous monitoring of the distance from obstacles during maneuvering. It works with the factory BMW PDC system, transmitting a signal to the control unit and the acoustic or visual warning system. Such a solution increases the safety of maneuvers in tight parking lots, underground garages, and in city traffic.

This component is particularly important in larger vehicles, such as the BMW X5 and X6, where precise parking sensors significantly facilitate the assessment of the distance from obstacles invisible from the driver's perspective.

Construction, color, and integration with the body

The sensor features a White finish, which allows for aesthetic matching to light-colored front bumpers or white-painted elements. As a result, it remains visually discreet after installation, maintaining stylistic consistency with the BMW body line.

The sensor housing is adapted for installation in the factory bumper socket, which facilitates the replacement of a damaged element without the need for modifications. The design provided by the manufacturer ensures proper sealing and stable seating in the bumper, which is crucial for the correct operation of the ultrasonic measuring system.

Operational parameters and advantages of use

As a component from the original BMW line, the sensor is adapted to work in demanding operating conditions – variable temperatures, moisture, and typical road loads. The use of a dedicated PDC sensor allows you to:

• maintain full compatibility with the factory parking system,
• preserve correct communication with the vehicle's electronics,
• reduce the risk of system errors resulting from the use of inappropriate replacements.

Precise obstacle detection translates into clear messages for the driver and more predictable behavior of the assistance system, which is important both in daily use and during maneuvers in more difficult conditions.

Condition, selection, and practical application

The offered parking sensor is a used component, which allows for the cost-effective restoration of the PDC system's efficiency while maintaining the original BMW specification. This solution is particularly beneficial for post-accident repairs or replacing a single, damaged sensor in the front bumper.

Before purchasing, it is worth verifying compatibility with your vehicle using the OEM part number and interchangeable numbers available in the technical specification. This facilitates the selection of the correct sensor variant for a specific BMW X5 or X6 configuration and minimizes the risk of installation problems.

System expansion and related components
