Purpose and function of the module

The presented tyre pressure controller works with the electronic installation of Mercedes C-Class (W204), E-Class Coupé/Cabrio (W207), and E-Class (W212) models, ensuring monitoring of tyre parameters and transmitting information to on-board systems. The module is responsible for receiving signals from sensors, processing them, and communicating with other controllers in the vehicle, which allows for early detection of pressure drops and increases driving safety.

Thanks to its factory design, the module maintains full compatibility with the vehicle's communication bus, which facilitates integration with the existing installation and reduces the risk of diagnostic errors after installation.

Application in Mercedes vehicles

The module is dedicated to tyre pressure monitoring systems in selected body versions of the Mercedes W204, W207, and W212. Using an original controller from the same construction group allows for maintaining the consistency of the vehicle's electronic configuration, which is important both for the correct operation of the TPMS system and for subsequent service diagnostics.

In case of replacement, it is recommended to verify compatibility with the specific equipment version and vehicle electronics configuration to ensure proper cooperation with other control modules.

Characteristics as a used component

The offered module comes from the secondary market, which is a beneficial solution for users looking for a factory component at a reasonable price. A used controller from the original production line retains the correct hardware and software architecture, allowing it to be used as a replacement for a damaged component without the need for interference with the mechanical system installation.

Before installation, it is recommended to perform a standard diagnostic procedure and – if necessary – adaptation or coding in accordance with the requirements of the specific vehicle unit.

Benefits of using an original TPMS module

• Consistency with the factory tyre pressure monitoring system in W204, W207, and W212 models.
• No need for electrical harness modifications due to the retention of the original connector architecture.
• Easier service diagnostics thanks to compatibility with factory software and test procedures.
• Possibility of economical TPMS system repair through the use of a used, original controller.
