Purpose and Function in the Roof System

The presented component belongs to the Soft Tops for Convertibles and Parts group and is intended for installation in the rear section of the BMW F12 Convertible body. It is responsible for the controlled lifting and lowering of the rear window during the operation of the convertible top, working in conjunction with other actuators, guides, and the roof frame. A properly functioning rear window lift is crucial for:

• the smooth opening and closing sequence of the soft top,
• proper sealing of the rear cabin area,
• maintaining the correct position of the window relative to the roof lining and body,
• reducing stress on the roof structure and seals.

Construction and Fit for BMW F12 Convertible

The rear window lift has been specifically designed for the BMW F12 convertible, taking into account the body geometry, roof kinematics, and the loads acting on the rear window. The original design ensures:

• precise vertical guidance of the window in the rear part of the vehicle,
• compatibility with factory mounting points in the body,
• cooperation with the factory installation and control of the convertible top. Thanks to this, the component can be used as a replacement for a damaged lift without the need for structural modifications, which simplifies servicing and reduces repair time.

Condition, Origin, and Benefits of Using a Used Part

The offered lift is a used part obtained from dismantling and is sold as a used BMW part. Such components, originating from original vehicles, allow for maintaining technical consistency with the rest of the roof system while reducing repair costs compared to new parts. Choosing an original used rear window lift is a particularly beneficial solution when:

• the existing component has suffered mechanical damage or operational wear,
• there are problems with the closing or positioning of the rear window,
• the roof system reports errors related to the operation of the rear part of the mechanism.

Professional Installation and Operation

Due to the complex construction of the convertible top in the BMW F12 Convertible, it is recommended to have the lift installed by a workshop experienced in servicing convertibles. Proper installation and calibration of the mechanism contribute to:

• correct synchronization of the rear window movement with other roof elements,
• reduced risk of recurring failures in the rear roof area,
• maintaining acoustic comfort and cabin sealing.
