Purpose and technical function

The presented hinge is a component of the hood support system in Mercedes W204 and W212 models, mounted on the left side of the vehicle. It is responsible for the correct geometry of opening and closing the hood, maintaining its alignment, and interacting with the locking mechanism. The hinge construction is integrated with solutions used in pedestrian protection systems, which is significant for post-accident repairs and restoring the vehicle to factory safety standards.

Color and visual fit

The component is finished in the Obsidian Black Metallic - 197 shade, which allows for an aesthetic match to Mercedes bodies painted in this color. In practice, this reduces the scope of additional painting work after installation, especially in repairs where only the hinge part or a section of the hood mounting structure is replaced. For body and paint shops, this means a faster process of restoring the vehicle to a functional state.

Vehicle placement and installation

The hinge is designed for installation on the left side of the engine bay, in the front section of the body. Proper placement is crucial for:

• maintaining the correct gap between the hood and the fenders,
• ensuring smooth hood movement when opening and closing,
• maintaining proper interaction with the hood lock and passive safety elements.

Due to the hinge's factory origin, its geometry and mounting points are consistent with original Mercedes solutions, which facilitates installation and adjustment in service conditions.

Product characteristics and service application

This is a part from the Hoods category, intended for service applications in Mercedes vehicles. It is particularly useful for:

• post-accident front-end repairs,
• replacing damaged hood mounting components,
• restoring full functionality of the pedestrian protection system.

The used nature of the component allows for cost-effective repairs while maintaining the original design and compatibility with the manufacturer's factory solutions. For workshops specializing in the Mercedes brand, this is a practical solution for reconstructing the front part of the body.
