Purpose and function in the TPMS system

The presented sensor operates at a frequency of 433 MHz, used in factory-fitted BMW tyre pressure monitoring systems. Its task is to continuously monitor the pressure in the wheel, transmit data to the control module in real-time, and signal any deviations from the set values on the driver's instrument cluster.

Thanks to the use of a dedicated OEM solution, the sensor works seamlessly with the vehicle's factory electronics, which promotes stable radio communication, reduces the risk of system errors, and facilitates adaptation after installation.

Technical and construction characteristics

BMW uses TPMS sensors in its vehicles that are designed for specific platforms and control units, which is why selecting the correct model is crucial for the proper operation of the system. The offered component belongs to the group of original solutions, which means:

• broadcasting characteristics designed specifically for BMW at 433 MHz,
• compatibility with the factory TPMS control unit software,
• maintenance of operating parameters in accordance with the vehicle manufacturer's requirements.

A sensor configured in this way allows for maintaining the consistency of the entire pressure monitoring system, without the need for universal replacements or additional programming beyond the standard service procedure.

Condition, selection, and practical application

The item is offered in used condition, which is a cost-effective solution for users looking for a proven OEM part at a reasonable price. In practice, this allows for restoring the full functionality of the TPMS system in situations such as replacing a damaged sensor, completing an additional set of wheels, or repairing after a collision.

When selecting a sensor for a specific BMW vehicle, it is worth paying attention to compatibility with the factory pressure monitoring system and the assigned catalogue and interchangeable numbers, which facilitate compatibility verification in service catalogues and diagnostic tools.

Benefits of using an original BMW sensor

Using an original TPMS sensor in a BMW vehicle translates into a number of practical benefits:

• Stable communication with vehicle electronics – the sensor is designed for specific control units, which reduces the risk of errors and system failure messages.
• Consistency with factory service procedures – handling, adaptation, and diagnostics are performed in accordance with the manufacturer's documentation.
• Tyre operation safety – a properly functioning TPMS system helps detect pressure drops faster, which is important for grip, braking distance, and tyre wear.

For users who consciously choose original components, such a sensor represents a reasonable compromise between cost and maintaining the factory operating parameters of the system.

System expansion and related components
