Purpose and function in the vehicle

The electric tailgate lift support strut in BMW X1 U11 and iX1 U12 models is responsible for the controlled movement of the tailgate, synchronized with the body electronics and the comfort access system. This component works in conjunction with control modules, position sensors, and buttons in the cabin and on the tailgate, enabling smooth opening and closing without the need for manual force.

The placement on the right side of the body has a structural significance – the strut acts as part of the tailgate support system along with hinges, gas springs, and the latch, ensuring stable guidance and even load distribution during operation.

Integration with the comfort system and automatic transmission

In vehicles equipped with an automatic transmission, the tailgate control logic is linked to drive modes and safety systems. This strut works with factory BMW electronics, ensuring that:

• tailgate movement is controlled based on vehicle position and transmission lock status,
• the system can respond to signals from the remote key, interior buttons, and sensors,
• consistency is maintained with comfort access functions and luggage compartment lighting.

As a result, replacing a damaged strut with an original component from the same design group restores full system functionality without the need for interfering with factory software.

Role in the Gas springs, locks, hinges and other parts system

The presented strut belongs to the Gas springs, locks, hinges and other parts group, which includes components responsible for the mechanical guidance and locking of the tailgate. In practice, it works with:

• gas springs that relieve the weight of the tailgate,
• hinges that guide the movement along the correct axis,
• the lock and striker, which are responsible for secure closing.

This combination of elements allows for repeatable, predictable tailgate movement, which is essential for both user comfort and the durability of the entire body system.

Characteristics of the used component

The offered strut is a used part, sourced from vehicle dismantling. For many BMW users, this represents a favorable compromise between cost and maintaining the original manufacturer's specifications. Using parts from the same model line allows for maintaining consistent performance parameters while reducing expenses compared to purchasing a new component.

When selecting a strut for a specific BMW X1 U11 or iX1 U12, it is crucial to verify compatibility with the part number and the vehicle's equipment configuration, which minimizes the risk of installation and electronic integration issues.
