Purpose and function of the airbag module

The described module is an airbag mounted in the central part of the steering wheel in the Mercedes ML W164 generation on the driver's side. It is an element of the airbag system that works with crash sensors and the SRS controller to inflate the airbag in a fraction of a second and reduce the forces acting on the driver.

Thanks to its factory design, the module maintains the correct geometry relative to the steering wheel, steering column, and seat, which translates into proper airbag deployment trajectory and stable mounting during vehicle operation.

Construction and compatibility with the SRS system

The steering wheel airbag module contains an integrated airbag and gas generator, designed to work with the factory safety system controller in the Mercedes ML W164. The electrical connectors are prepared for direct connection to the steering wheel wiring harness, which facilitates installation and reduces the risk of installation errors.

Original manufacturing ensures:

• consistency with factory SRS system parameters,
• appropriate airbag inflation characteristics,
• proper cooperation with crash sensors and the controller.

As a result, the module can be used both when replacing a damaged airbag and when restoring full functionality of the safety system after post-accident repairs.

Condition, verification, and service application

The item is offered as a used part, which allows for an economical repair of the safety system while maintaining the manufacturer's original specifications. Such components are commonly used in professional workshops specializing in post-accident repairs, where both technical compliance and cost control are important.

Before installation, it is recommended to perform standard SRS system diagnostic procedures, including reading and clearing any potential errors, as well as verifying the correctness of the electrical installation. A correctly selected and installed steering wheel airbag module allows for the restoration of full functionality of the airbag system in the Mercedes ML W164.

Benefits of using an original airbag module

Using an original steering wheel airbag in a Mercedes ML W164 provides a number of practical benefits:

• Factory fit – proper alignment with the steering wheel and covers, without the need for modifications.
• Consistency with the SRS system – maintaining the parameters specified by the vehicle manufacturer.
• Possibility to restore full functionality of the safety system after a collision.
• A cost-effective solution compared to new parts while maintaining the original design.

For workshops and individual users, this means the possibility of carrying out repairs in a technically correct and economically rational way.
