Intended Use and Vehicle Placement

The presented window regulator assembly with motor is intended for installation in the front right door of the BMW F series Gran Coupé. Placement on the exterior side of the vehicle (O/S) signifies compatibility with the specific door geometry, guides, and body mounting points, which facilitates installation and reduces the need for additional modifications.

This component belongs to the group responsible for electric window control, therefore its correct operation directly impacts:

• smooth window raising and lowering,
• compatibility with factory control buttons,
• proper window sealing within the door frame.

Technical Characteristics and Compatibility

The window regulator with motor has been designed by BMW as a component compliant with factory installation and safety standards. The construction is based on a dedicated guide system and an electric drive that transfers torque to the window lifting mechanism. This ensures the correct window movement speed and stable guidance throughout its operating range.

The product has an assigned OEM part number and interchangeable numbers, which simplifies selection by manufacturer identifiers and allows verification of compatibility with specific equipment versions. In practice, this means precise vehicle matching based on catalog data or VIN number, without the need for electrical system modifications.

Condition, Functionality, and Service Application

The offered part is in used condition, allowing for economical window system repair while maintaining original BMW construction. This type of part is particularly suitable in situations where:

• mechanical damage to the regulator guides or cables has occurred,
• the regulator motor has stopped responding to commands,
• there are problems with the window stopping at random positions.

Using a complete window regulator assembly with motor reduces service time as it eliminates the need to separate the mechanism and drive. For workshops and individual users, this means simpler installation and a lower risk of errors during door reassembly.

Benefits of Choosing an Original BMW Window Regulator

Choosing an original window regulator with motor for the BMW F Gran Coupé ensures:

• factory fitment to the door structure and mounting points,
• compatibility with the vehicle's electrical system operating parameters,
• stable window operation without excessive play or vibrations,
• the possibility of using existing wiring harnesses and connectors without modifications.

This makes window system repairs predictable, and the risk of compatibility issues is reduced compared to aftermarket alternatives of uncertain origin.
