Purpose and function of the stalk assembly

The described steering column stalk assembly with clock spring and sensor is structurally matched to Mercedes C215 and W220 series models. It is responsible for handling functions located at the steering column, and the integrated clock spring and sensor enable proper communication with the vehicle's electronic systems. This ensures the consistency of control system operation, which is important for both safety and driving ergonomics.

Construction and placement in the vehicle

The element belongs to the Switches, control elements and ignition locks group, which means it works with systems responsible for controlling vehicle functions from the driver's position. The location specified as rear – right side indicates a specific mounting position in the vehicle, which facilitates selection and planning of service work. Integrating the stalks with the clock spring and sensor into one assembly reduces the number of connections and potential points of failure.

Benefits of using an original Mercedes component

The product comes from the Mercedes brand, which in practice means maintaining factory geometry, the correct operating range, and compatibility with the electrical installation of a given model. Using an original stalk assembly with clock spring and sensor allows you to:

• maintain predictable operation of control systems at the steering column,
• minimize the risk of communication errors with the vehicle's electronics,
• reduce the time required for diagnostics and adjustment during installation. This solution is particularly beneficial for repairs where maintaining compliance with the vehicle's factory specifications is crucial.

Condition characteristics and service application

The item is offered in used condition, making it an attractive cost-effective alternative while maintaining proper functionality. This type of stalk assembly with clock spring and sensor will work well both for standard replacement of a damaged component and for comprehensive service work within the steering column. Before installation, it is recommended to perform a standard inspection of the installation and the correctness of the mounts to fully utilize the potential of the part.

Expansion of the control system in a Mercedes

If you are planning a comprehensive repair or upgrade of the control zone at the steering column in your Mercedes and need other elements from the same group, such as additional stalks, control modules, or ignition lock elements, check the available parts in the Mercedes switches, control elements and ignition locks category.

Safety in selecting used components

When choosing used control elements, it is worth paying attention to structural compatibility, the condition of connectors, and the correct operation of sensors. To better plan the purchase and verification of components from the secondary market, a guide on the safe selection of vehicle system elements may be helpful – detailed tips can be found in the article Second-hand braking system: how to safely select discs, calipers, and ABS?, which presents universal principles for evaluating used parts in a store like Global Parts.
