Application and Role in the BMW Braking System

The presented brake pressure sensor operates within the hydraulic system, transmitting information about the current pressure generated during braking to the control units. This data is used by the ABS system, among others, to modulate braking force at the wheels, as well as by other driver assistance systems. This ensures the car maintains stable trajectory, and the response to brake pedal application remains repeatable and predictable.

The component is dedicated to BMW models from the E and F families listed in the title, ensuring proper structural and electrical compatibility. Using an original sensor from the same component group as factory-installed parts minimizes the risk of communication errors with the vehicle's electronics.

Benefits of Choosing an Original BMW Sensor

By choosing this brake pressure sensor, you gain a component designed specifically to work with the ABS system in a given vehicle type. This means:

• preservation of the braking system's factory operating characteristics,
• proper cooperation with the ABS wheel speed sensor system,
• consistency with the software of the control units used in the specific BMW model,
• reduced risk of errors and warning lights on the dashboard.

As a part from the ABS wheel speed sensor category, this component is a crucial element of the entire measurement chain responsible for driving safety. Proper selection by OEM number and interchangeable part numbers allows for reliable identification of compatibility with a specific equipment version.

Professional Selection by OEM and Interchangeable Part Numbers

This sensor has an assigned OEM part number and a set of interchangeable part numbers, which facilitates matching it to a specific vehicle instance. When selecting, it is advisable to use the VIN and manufacturer's designations to avoid mistakes between similar variants used in different model years or engine versions.
