Purpose and function in the vehicle

The offered steering angle sensor integrated with the slip ring and airbag harness is designed for installation in Mercedes W470 class models. The element works with the steering column, transmitting information about the current steering wheel position to the control units and ensuring signal continuity to the driver's airbag.

The vehicle location specified as rear – right side indicates a specific mounting position in the given system, which facilitates correct identification of the part during selection and service. Thanks to this, the mechanic or user can be sure that the component will work with the appropriate part of the vehicle's installation.

Construction and technical properties

The presented element combines several functions in one housing: steering angle reading, signal routing in the rotating column, and handling the airbag circuit. This design allows for:

• precise monitoring of the steering wheel position by electronic stability control systems,
• safe routing of wires in the rotating steering wheel assembly,
• maintaining the continuity of the driver's airbag electrical connection.

This solution is particularly important in vehicles equipped with advanced assistance systems, where the accuracy of the steering angle reading affects the reaction of the stability system and driving comfort.

Benefits of using an original used component

Choosing an original used component for a Mercedes allows you to maintain the factory operating parameters of electronic systems without the need to invest in a new part. A properly selected steering angle sensor with a slip ring and airbag harness:

• maintains compatibility with factory control units and electrical installation,
• reduces the risk of communication errors in safety systems,
• allows for optimizing repair costs while maintaining high-quality performance.

This solution is particularly beneficial when servicing vehicles that are used intensively, where both reliability and a reasonable repair budget are important.

Application in safety and comfort systems

The steering angle sensor with airbag ribbon is linked to many vehicle systems, such as the electronic stability control, power steering, or modules responsible for passive safety. A properly functioning element:

• supports stable vehicle handling in emergency situations,
• ensures correct communication between the steering wheel and control units,
• minimizes the risk of errors related to the driver's airbag.

Thanks to this, the driver receives predictable vehicle behavior, and safety systems can react according to the manufacturer's specifications.
