Application and Compatibility

The presented PDC sensor is designed for BMW F-series models, including BMW F45, F46, X1 F48, and X4 F26, where it works with the factory parking assist system. Thanks to the use of an original BMW solution, correct cooperation with control modules, wiring harness, and vehicle software is maintained.

The grey finish of the housing allows for an aesthetic match to the bumper in the appropriate color specification, and the sensor's design is prepared for installation in the factory socket, without the need for mechanical modifications.

Construction and Function of the PDC Parking Sensor

The BMW PDC parking sensor operates using ultrasonic waves, monitoring the distance between the vehicle and obstacles in the bumper area. The return signal is processed by the system controller, which generates acoustic warnings and – depending on the car's equipment – visual representation on the multimedia system screen.

The original design ensures:

• correct distance measurement characteristics within the range specified by the manufacturer,
• stable operation under typical operating conditions (moisture, temperature changes, road dirt),
• compatibility with factory mounting brackets and rings in the bumper.

Benefits of Using an Original BMW Sensor

Using an original PDC sensor in a BMW ensures the consistency of the entire parking assistance system. Factory fitment reduces the risk of system errors, accidental dashboard messages, and problems with coding or adaptation. A used OEM part is a cost-effective alternative to a new part while maintaining proper functionality.

In practice, this means:

• no need for electrical system modifications,
• preservation of the original PDC system logic,
• easier diagnostics in case of potential future malfunctions.

Condition and Service Purpose

The offered sensor is a used component, primarily intended as a replacement part for accident repairs, bumper damage, or failure of a single sensor in the PDC system. This type of component allows for the restoration of full parking system functionality without the need to interfere with other installation components.

Before installation, the standard service procedure is recommended: check connectors, inspect the wiring harness for mechanical damage, and verify system operation after installation using onboard diagnostics.
