Vehicle Application and Placement

The presented window regulator with motor has been specifically designed for installation in the rear left door of the BMW F46 Gran Tourer. It is responsible for driving and guiding the window vertically, working in conjunction with the vehicle's factory electric controls. Its dedicated placement on the vehicle minimizes the risk of fitment issues and simplifies installation in place of the original component.

Function and Performance Parameters

The regulator integrated with the electric motor is responsible for:

• smooth raising and lowering of the window in the rear left door,
• operation with the factory window control buttons,
• maintaining the window's stable position at the set level,
• reducing window play and vibrations during driving.

Thanks to its construction, which aligns with BMW's factory solutions, the component maintains the correct window guide geometry and appropriate motor operating characteristics. This is particularly important in vehicles equipped with electric control for all windows, where the consistent operation of each mechanism contributes to user comfort.

Original Origin and Replacement Numbers

The window regulator with motor belongs to the group of original BMW components, which means compliance with factory quality and fitment standards. The part has an assigned OEM number and a set of interchangeable numbers, allowing for precise verification of compatibility with a specific version of the BMW F46 Gran Tourer. The presence of reference numbers facilitates the selection of the correct part in case of previous modifications or changes in the manufacturer's catalogs.

Condition, Installation, and Service Application

The component is offered as a used sub-assembly, which represents a reasonable compromise between repair cost and maintaining the vehicle's original specifications. In practice, this allows for:

• restoring the functionality of the electric window control after failure of the factory mechanism,
• reducing service costs while retaining OEM parts,
• replacing the complete regulator + motor assembly instead of repairing individual components.

Thanks to its dedicated placement in the rear left door, installation proceeds similarly to factory procedures – after removing the door trim and unfastening the old mechanism, the new assembly can be fitted into the existing mounting points.
