Application and body fitment

The presented rear left door is dedicated to the Mercedes B-Class W245 generation and has been designed as a component mounted in the rear part of the body on the driver's side. Thanks to the factory design, the correct mounting points for hinges, locks, and window guides are preserved, which facilitates installation and allows for precise adjustment of the gaps between body panels.

Its placement on the vehicle in the rear left body zone makes this component particularly important for the safety and comfort of rear-seat passengers, as well as for the lateral structural rigidity of the vehicle.

Paint color and finish

The door is finished in the factory Kosmos Black Metallic color with paint code 191, characteristic of many Mercedes equipment configurations. The metallic paint coating provides a deep black color with a subtle pearl effect, allowing for an aesthetic match with other body components in the same color.

Such a choice of paint reduces the need for full repainting of the component after installation, which in many cases shortens repair time and lowers costs while maintaining a consistent appearance of the entire vehicle.

Performance and structural parameters

The door belongs to the Doors and door panels category, which means it is a full-fledged element of the side body structure, not just an outer skin. The properly selected structural weight helps maintain the correct rigidity while not negatively affecting the operation of the hinges and lock, provided it is installed correctly.

The component has an assigned OEM part number and interchangeable numbers, which facilitates verification of compatibility with a specific vehicle equipment version. This allows for precise selection of the door for a given Mercedes model, minimizing the risk of installation problems.

Condition, origin, and benefits of choosing a used part

The offered rear left door is a used part, which is a reasonable compromise between repair costs and maintaining the manufacturer's original quality. Choosing a dismantled component allows you to maintain the factory body line while reducing expenses compared to purchasing a new component.

A used body component is also an advantageous solution in terms of operation – the original Mercedes construction ensures proper fitment to pillars, sills, and seals, which translates into correct door closing, proper acoustic insulation, and limiting moisture ingress into the interior.

Installation recommendations and additional resources

Before installation, it is recommended to verify the compatibility of the part number and interchangeable numbers with the vehicle documentation or the manufacturer's catalog, as well as to check the condition of accompanying elements such as hinges, locks, or seals. Properly performed installation allows for the restoration of full functionality of the side body zone and the aesthetic appearance of the vehicle.

If you are planning a comprehensive repair or modernization of the side body zone in your Mercedes and need other components from the same group, such as outer skins, door frames, or reinforcements, check the available parts in the Mercedes Doors and door panels category.
