Purpose and function of the component

The presented hinge arm is dedicated to installation on the left side of the body in the BMW F30 series model, where it is responsible for the smooth opening and closing of the trunk lid. The design has been engineered to maintain the correct axis of rotation, even load distribution, and stable lid guidance, which translates into comfort during daily vehicle use.

The component works with the factory body and lid mounting system, ensuring that after proper installation, it is possible to maintain tightness, the correct body line, and the proper operation of the lock and seals.

Color and visual fit

The hinge arm is finished in Black Sapphire Metallic - 475, which allows for an aesthetic match to bodywork painted in the same color. For vehicles in this shade, this reduces the need for additional paint work in the area of visible hinge fragments, and with proper installation, it enables a consistent look for the rear of the car.

Selecting a component in an identical color is particularly important for post-accident repairs and when replacing individual body components, where both correct geometry and visual surface continuity are essential.

Technical characteristics and installation

The trunk lid hinge arm has been designed as an original BMW part, which means it retains factory mounting points and is compatible with the F30 body structure. This facilitates installation in an independent service center or body shop, without the need for modifications or adjustments to the holes.

The used nature of the component allows for an economical repair of the rear body section while maintaining the manufacturer's original specifications. When replacing, it is recommended to check the lid alignment, adjust clearances, and verify the operation of the actuators and lock to achieve even fitment and proper closing.

Application in BMW body repairs

The left trunk lid hinge arm is primarily used for repairs after rear collisions, replacing corroded elements, or correcting trunk lid geometry. Using an original component allows for compliance with BMW service documentation and facilitates subsequent adjustments within the rear body area.

Why choose an original used component

The original BMW trunk lid hinge arm ensures dimensional compatibility with the body, which is crucial for the durability of the repair and the subsequent operation of the vehicle. A used component allows for cost reduction compared to a new part, while maintaining the factory design and performance characteristics.
