Purpose and body fitment

The presented fender is designed as a component for the front left part of the body in W166 series models. Its geometry is consistent with factory mounting points, which facilitates installation and allows for maintaining correct gaps between the hood, doors, and bumper. As a result, after replacement, it is possible to achieve an aesthetic, uniform fit, which is important from both an appearance and aerodynamics perspective.

Characteristics of the Obsidian Black Metallic paint

The fender is finished in Obsidian Black Metallic, factory-coded as 197. This is a popular, dark metallic shade used in many units of this series, which effectively masks minor dirt and highlights the body lines. Using the original color makes it easier to match the vehicle's existing paintwork, limiting the scope of any potential paint jobs and accelerating the visual repair process.

Protective and structural function

The fender plays an important role in protecting the body structure from external factors. It is responsible for:

• shielding the front wheel from the outside,
• limiting the ingress of water, mud, and small stones onto suspension components,
• stable mounting of adjacent body components, such as the bumper or wheel arch liner.

By maintaining the factory geometry, this component supports the proper operation of other body panels and the maintenance of proper lateral rigidity in the wheel arch area.

Condition of the component and service application

The offered fender is a used part, which makes it a cost-effective solution for post-accident repairs, restorations, and restoring the vehicle to working order after operational damage. Choosing an original, used body component often allows for cost savings compared to new parts, while maintaining proper fitment to the vehicle's structure. This type of component is particularly useful in situations where the priority is a quick and technically correct reconstruction of the front body section.

Support with selection and additional information

In case of doubts regarding compatibility with a specific equipment version or vehicle year, it is worth verifying the manufacturer's markings and comparing the shape and mounting points with the currently installed component. A used fender can also be a good starting point for further body and paint work when visual matching to the individual condition of the body is necessary.
