Purpose and compatibility with Mercedes models

The presented driver's airbag has been designed specifically for popular classic models such as the W124, W140, and W202. The airbag module construction is adapted to the factory steering wheel and steering column, which allows for maintaining compatibility with the vehicle's original safety system. As a result, this component can be used both for replacing a damaged airbag and for restoring the completeness of the SRS system after post-accident repairs.

Construction and placement in the vehicle

The driver's airbag is mounted in the front part of the cabin, centrally in the steering wheel hub. The airbag module is an integral part of the steering wheel assembly, working in conjunction with collision sensors and the safety system controller. The black outer casing is color-matched to typical Mercedes interior configurations, which allows for maintaining a consistent, factory look of the cockpit.

The module's design solution enables proper assembly with existing system elements, such as the clock spring or the SRS controller, provided they are compatible with the specific vehicle equipment version.

Visual characteristics and ergonomics

The black color of the driver's airbag is neutral and practical, making it effective at masking typical signs of interior wear. The uniform front surface promotes the readability of other elements on the steering wheel, such as buttons or the manufacturer's logo (if present in the given configuration). This type of finish helps maintain the consistent, understated character of the cockpit, typical for Mercedes models from the production period in question.

Product condition and service application

The driver's airbag is offered as a used component, which makes it an attractive solution for vehicle repairs where the priority is to maintain original components at reasonable service costs. This type of part can be particularly useful for:

• restoring the completeness of the SRS system after previous removal,
• replacing a damaged airbag module in the steering wheel,
• renovating the interior of classic Mercedes models while maintaining their original character.

Before installation, it is recommended to verify compatibility with the specific vehicle equipment version and to have the work performed by a specialized service center, adhering to safety procedures regarding airbag systems.

Safety, installation, and technical aspects

As a passive safety system component, the driver's airbag module requires particularly careful installation and post-installation diagnostics. Proper connection to the electrical system and the SRS controller is crucial for the correct operation of the entire system. After completing the work, it is recommended to perform an airbag system control test using an appropriate diagnostic interface.

Due to the nature of the component, all installation work should be carried out with the vehicle's power supply disconnected and in accordance with the manufacturer's procedures for handling airbags. Such an approach minimizes the risk of system malfunction and helps maintain a high level of user safety.
