Purpose and function of the strut

The presented strut is a component of the system supporting the opening and closing of the trunk lid in the electric drive version. Mounted on the left side of the vehicle, it works with the control module and other mechanism components, stabilizing the movement of the lid and reducing stress on the hinges. The appropriate operating characteristics of the strut ensure even guidance of the lid, which translates into comfort of use and less wear on the mounting elements.

Construction and fit for BMW F31

The strut has been constructed as a part dedicated to the 3 Series in the F31 body, taking into account the geometry of the trunk lid and its range of motion. The appropriate working length and piston stroke are selected to:

• ensure stable support of the lid in the full range of opening,
• maintain the proper lifting and lowering speed,
• minimize loads transferred to the hinges and mounts.

Thanks to a design consistent with factory standards for Gas springs, locks, hinges and other parts for this series, installation takes place at existing mounting points, without the need for bodywork or electrical system modifications.

Benefits of using an original strut

Using the correct strut on the left side of the trunk lid has a direct impact on safety and ease of use. A properly selected component:

• reduces the risk of the lid falling spontaneously under adverse conditions (e.g., low temperature, wind),
• ensures predictable, repeatable lid movement throughout the entire operating cycle,
• protects mounts and hinges from excessive forces, extending their durability,
• maintains proper cooperation with the electric drive, which is crucial for the longevity of the entire system.

For the user, this means stable operation of the mechanism, convenient access to the luggage compartment, and preservation of the vehicle's factory functionality.

Characteristics of the used component

The offered strut is a used part, sourced from dismantling, which allows for economical repair while maintaining compliance with the original specification. Such components are frequently chosen for servicing electric tailgates because they allow for matching the existing system without the need for software or installation modifications. The correct selection of the mounting side and the type of strut is of key importance for the proper operation of the entire mechanism.

Technical support and related components

In the case of comprehensive maintenance of the vehicle's drive system, including elements cooperating with the body electronics, it is worth paying attention to the compatibility of parts and their selection for a specific model version. When diagnosing other components, such as the clutch or dual-mass flywheel, the guide article Clutch and dual-mass flywheel – diagnostics and selection of parts for the drive system may be helpful, which discusses the principles of selecting elements also in the context of used parts.
