Purpose and function in the vehicle

The offered steering angle sensor integrated with a slip ring and airbag connector is a component mounted within the steering column, responsible for transmitting information about the steering wheel position to the vehicle's control units. It works with electronic stability control systems, power steering, and passive safety systems, ensuring consistent operation of the electronics monitoring the vehicle's behavior on the road.

Thanks to its dedicated fitment for specific Mercedes generations, the component maintains the correct mounting geometry and allows for proper calibration during service. The vehicle placement specified as rear – right side allows for unambiguous assignment of the part to the correct position in the system, which facilitates selection and eliminates the risk of errors when ordering.

Construction and technical properties

The element combines a steering angle sensor and a slip ring in one housing, which is responsible for transferring electrical signals to the airbag and steering wheel buttons. This design reduces the number of connections, improves reliability, and facilitates service installation. The architecture used is consistent with factory solutions used by Mercedes, which translates into compatibility with original wiring harnesses and control units.

The sensor housing is designed for stable positioning on the steering column, and the internal signal paths and connectors are adapted to work in conditions typical for the vehicle interior – taking into account vibrations, temperature changes, and long-term operation. As a result, the component can be used as a replacement for the factory-installed element without the need for installation modifications.

Condition, origin, and service application

The product is offered as a used part, which allows for cost-effective repair of the steering system while maintaining compliance with factory specifications. This type of component is particularly useful in situations where errors related to the steering angle sensor, malfunction of the electronic stability control system, or communication with the airbag module appear in the vehicle.

Due to its complex function in the vehicle, it is recommended to entrust the installation to a workshop with access to appropriate diagnostics, enabling adaptation and calibration of the sensor after installation. A correctly selected and installed element restores the proper cooperation of electronic systems, which translates into predictable vehicle behavior while driving.

Part selection based on technical parameters

When choosing this type of component, it is crucial to match it to the specific model and equipment version. To this end, it is worth paying attention to:

• compatibility with the vehicle platform (body series and generation),
• type of steering system and safety systems used,
• placement on the vehicle to avoid incorrect installation.

Additionally, comparing the housing design and connectors with the element removed from the vehicle may be helpful. In case of doubt, it is worth consulting a mechanic or the store's technical department to confirm compatibility before installation.
