Purpose and function of the component

The presented hinge operates in the rear body section on the left side, responsible for the proper support and guidance of the boot lid. The design has been engineered for the specifics of BMW F-series models, which translates into:

• stable alignment of the lid during operation,
• proper fitment with the bodywork and lock,
• reduction of stress within the mounting points and the lid sheet metal.

As a result, the lid opens and closes smoothly, without unwanted play or jerking, which is important for both user comfort and the durability of the entire boot lid assembly.

Estoril Blue Metallic B45 color and visual matching

The component is finished in Estoril Blue Metallic B45 paint, characteristic of sport-configured BMW models. Using a hinge in this color allows for reducing the scope of paintwork in the area of the lid recess and its edges, which is particularly important during post-accident repairs or when replacing individual body components.

Selecting a component in the correct shade facilitates maintaining a consistent aesthetic of the rear of the vehicle and minimizes the risk of tone differences in the paint visible when the lid is open.

Mounting characteristics and application

The left-side boot lid hinge has been designed as a part structurally compliant with the factory BMW standard. In practice, this means:

• retaining the original mounting points on the body and the lid,
• compatibility with the standard lid opening geometry,
• ability to work in a set with factory gas struts and the lock.

Such a solution facilitates installation in workshop conditions and allows for restoring the original functionality of the rear of the vehicle without the need for structural modifications.

Product category and service application

The component belongs to the Gas struts, locks, hinges, and other parts group, i.e., components responsible for the mechanics of opening, supporting, and locking lids and covers. Replacing the hinge is recommended in situations where:

• the lid operates with noticeable resistance or lifts unevenly,
• there are deformations after a collision in the rear part of the body,
• leaks appear resulting from improper closing of the lid.

Choosing an original solution from this group allows for maintaining predictable lid behavior and reducing the wear of cooperating elements, such as gas struts or the lock.

Condition of the component and practical benefits of the purchase

The offered hinge is a used part, which is a reasonable compromise between the cost of repair and maintaining the factory specification. In practice, this allows you to:

• lower the cost of restoring the efficiency of the boot lid,
• maintain the original construction and geometry of the body,
• preserve compliance with the factory BMW standard in the rear area of the vehicle.

For workshops and individual users, this means the possibility of performing a repair in a technically correct manner while maintaining control over the service budget.
