Purpose and function of the door stopper

The stopper is mounted in the hinge area of the rear right door leaf and is responsible for precisely positioning the door at several stable opening points. Thanks to this:

• the door does not open too wide, which reduces the risk of damage to the bodywork or adjacent vehicles,
• the door leaf remains in the selected position even on a slight incline,
• the door movement is smooth and predictable, which improves user comfort.

The element is structurally matched to the BMW F45 series body, which translates into proper door guidance and the maintenance of the factory operating characteristics of the mechanism.

Compatibility and fit for BMW F45 / F45 LCI

The rear right door stopper has been designed specifically for the BMW F45 platform, including the LCI facelift versions. This means:

• retention of original mounting points in the door and body pillar,
• compatibility with factory hinge and door panel geometry,
• no need for structural modifications during installation.

By using a part from the same construction group as the factory equipment, you achieve technical consistency with other body elements and predictable door behavior in daily use.

Performance characteristics and advantages of use

A properly selected door stopper has a direct impact on the ergonomics of using the rear seat and the safety of the bodywork. Using a dedicated component for the rear right side of the vehicle allows you to:

• maintain appropriate resistance when opening and closing the door,
• reduce loads acting on hinges and door panels,
• minimize noise resulting from uncontrolled "popping" of the door from intermediate positions.

The original design from the Doors and door panels group helps maintain the factory character of the mechanism's operation, which is particularly important during post-accident repairs or when replacing worn components in vehicles used on a daily basis.

Condition, origin, and installation aspects

The offered stopper is a used component, which allows for economical repair while maintaining the manufacturer's original specifications. The part comes from a dismantled BMW vehicle, ensuring full structural compatibility with the factory solution.

During installation, it is recommended to:

• check the condition of the mounts in the door and body pillar,
• verify the interaction of the stopper with the hinges and door seals,
• verify the smoothness of operation after tightening all mounting points.

This type of replacement is a standard service procedure in the bodywork area and does not require interference with the vehicle's electrical system.
