Purpose and function of the component

The presented hinge is designed for installation on the left side of the rear lid in the CL-Class 203 series coupe body. It is responsible for guiding and supporting the trunk lid, bearing loads during opening, closing, and maintaining the lid in the correct position relative to the body. As a part from the Trunk lids and rear parts group, it works in conjunction with the lock, actuators, and seals, affecting the tightness and proper fit of the rear bodywork.

Color and body fitment

The component is factory-finished in Obsidian Black Metallic, identified by paint code 197. For many users, this means the possibility of maintaining visual consistency of the rear body section without the need for immediate repainting of the entire lid. The hinge is prepared for use with original mounting points on the body and the trunk lid, which facilitates installation and reduces the need for additional bodywork modifications.

Benefits of using an original Mercedes hinge

Using an original hinge in the CL203 model allows for maintaining the factory opening geometry, which is important for both user comfort and the durability of the entire rear lid system. A properly selected component:

• ensures repeatable, smooth guidance of the trunk lid,
• reduces the risk of stress on the body panels and rear window edges,
• facilitates correct alignment of gaps between the lid, fenders, and bumper,
• works with original actuators and the lock without the need for adaptation.

As a result, the repair of the rear body section is more predictable, and the final result is closer to the factory finish.

Characteristics of the used component

As a used part, the trunk lid hinge has already been in service, which allows for its more cost-effective use in post-accident repairs or body maintenance. This solution is particularly beneficial for comprehensive body and paint work, where both technical correctness and cost optimization are important. Its original Mercedes origin promotes compatibility with factory components of the rear body section.

Selection and additional technical information

When selecting a trunk lid hinge for a specific CL203 unit, it is worth paying attention to the mounting side, body type, and compatibility with the mounting system on the lid and body. Manufacturer markings, OEM part numbers, and interchangeable numbers can be helpful in verifying compatibility with a specific equipment version. In case of doubt, it is worth comparing the design of the component with the part currently installed in the vehicle.
