Purpose and function in the PDC system

The presented sensor belongs to the Parking Sensors category and works with the factory PDC system in the BMW F20/F21 series. It is responsible for precise distance measurement from obstacles using ultrasonic waves, transmitting data to the control unit, which generates audible signals and – depending on the car's configuration – a visualization on the multimedia system screen.

As an OEM component, it ensures:

• proper cooperation with the factory wiring harness and PDC control unit,
• stable operation under typical urban and road driving conditions,
• maintenance of the original performance parameters of the parking assistance system.

Portimao Blue Metallic C31 color and visual fit

The sensor is finished in Portimao Blue Metallic – C31, used in the BMW paint palette. This ensures that the visual consistency of the bumper is maintained after installation, without the need for additional painting of the component. This is a particularly beneficial solution for spot repairs when a single sensor is being replaced in an already painted bumper.

Selecting a component in the correct color reduces the risk of shade differences and shortens the time required to return the vehicle to service after minor collisions or parking damage.

Condition, origin, and technical aspects

The offered BMW parking sensor is an original BMW group component, sourced from disassembly. The used condition means that the component has been previously operated but retains full functionality within the scope for which it was designed. In practice, this allows for an economical repair of the PDC system while maintaining factory quality and fitment.

As an OEM part, the sensor has an assigned part number and interchangeable numbers, which facilitates verification of compatibility with a specific vehicle configuration. Before purchasing, it is recommended to compare the data with service documentation or the car's equipment configuration to ensure proper operation in a given BMW F20/F21 unit.

Benefits of using an original parking sensor

Using an original PDC sensor in a BMW 1 Series brings a number of practical benefits:

• Factory fit – the appropriate housing geometry and connector ensure proper seating in the bumper socket and trouble-free connection to the installation.
• Color consistency – the Portimao Blue Metallic C31 paint allows for a uniform body appearance without additional paint work.
• Stable PDC system operation – maintaining the parameters specified by the manufacturer minimizes the risk of false alarms or lack of system response.
• Economical repair – a used OEM component represents a reasonable compromise between cost, quality, and durability.

How to select and use a used PDC sensor

When selecting a parking sensor for a BMW F20/F21, it is worth paying attention to compatibility with the vehicle's equipment and the manufacturer's numbering. It is helpful to compare the markings with the existing component or use a parts catalog based on the VIN. Installation should be performed in a way that ensures proper seating in the bumper and tightness of the socket, which is important for the durability and correct operation of the ultrasonic sensor.
