Function and application in the steering system

This steering wheel angle sensor, wiper stalk, and airbag squib assembly is responsible for precise steering wheel position reading and transmitting signals to electronic stability control systems, power steering, and other comfort modules. The integrated wiper stalk allows for convenient control of the wipers from the steering column, while the built-in ribbon cable (so-called squib) ensures a continuous electrical connection to the airbag throughout the full range of steering wheel rotation.

Thanks to the factory Mercedes design, this component is optimized for communication with the vehicle's bus, which promotes stable operation of electronic systems and reduces the risk of controller errors.

Benefits of using an original Mercedes assembly

Using an original sensor and stalk assembly in Mercedes W169 and C209 models allows for maintaining consistent performance parameters with the vehicle's factory configuration. This is particularly important for components responsible for active and passive safety, where the correct interpretation of signals from the steering angle sensor affects the operation of stability systems and the airbag system.

The main advantages include, among others:

• factory fitment to the steering column and vehicle electrical installation,
• preservation of the original wiper stalk operation logic,
• compatibility with Mercedes controller software,
• reduction of incompatibility risks typical of universal aftermarket replacements.

Operational and installation characteristics

The component comes from the Switches, control elements and ignition locks group, meaning it is designed as a part that interacts directly with the vehicle user and key control modules. The sensor, stalk, and squib assembly is mounted on the steering column, and its replacement requires removing the steering wheel and following safety procedures related to the airbag system.

The product is offered as a used original part, which allows combining a cost-effective purchase with the preservation of factory quality and fitment. In many cases, this is an effective solution for troubleshooting faults related to steering angle sensor errors, wiper operation issues, or airbag circuit interruptions.

Why choose used original Mercedes parts

For premium brands such as Mercedes, choosing used original components allows maintaining a high level of comfort and safety without the need to incur the costs of purchasing new components. This applies to both electronic and mechanical elements, including assemblies mounted on the steering column.
