Vehicle Application and Function

The offered mechanism belongs to the Wiper Motors and Linkages category and is specifically designed for Mercedes-Benz A-Class W176 generation and CLA C117 models. It is responsible for the precise guidance of wiper arms on the windshield, maintaining the correct operating range, and synchronized movement of both blades, which is crucial for driving comfort and safety.

Its placement on the vehicle in the windshield area allows for direct interaction with the wiper motor and arms, minimizing play and unwanted vibrations. This ensures system stability even at higher speeds and during heavy precipitation.

Construction and Technical Compatibility

The mechanism has been developed as an original part for the Mercedes brand, meaning it retains factory mounting points and is compatible with the cowl panel and body structure. The mounting hole spacing, linkage geometry, and connection method to the wiper motor are tailored to the specific requirements of the W176 / C117 platform.

The component is assigned an OEM part number and related interchangeable numbers, facilitating unambiguous identification and selection of the correct variant for a specific equipment version. In practice, this means it can be directly installed in place of a worn or damaged mechanism without the need for modifications.

Condition, User Benefits, and Installation

The product is offered as a used genuine part, allowing for a favorable purchase cost while maintaining factory construction and fit. Compared to low-cost aftermarket alternatives, an original mechanism offers better body compatibility, appropriate rigidity, and predictable performance over a longer service life.

Key installation benefits include:

• factory mounting points matched to the W176 / C117 body,
• designed to work with the original wiper motor,
• maintaining correct arm movement geometry on the windshield.

A system configured in this way simplifies servicing, reduces replacement time, and minimizes the risk of incorrect wiper positioning after installation.

How to Choose the Right Mechanism for Your Mercedes

To ensure the selected mechanism is fully compatible with your car, it is advisable to verify the OEM part number and interchangeable numbers against your vehicle's documentation or service system data.
