Vehicle Application and Placement

The regulator is dedicated for installation in the rear right door, which guarantees proper fit to the body structure and factory mounting points. It is responsible for transferring the drive from the control mechanism to the window, holding its position in the guides, and ensuring smooth movement throughout its full operating range.

Thanks to precise adaptation to the specific mounting location, the window's operating geometry, sealing when closed, and proper cooperation with seals and the door frame are maintained.

Technical and Functional Characteristics

The window regulator belongs to the group of components responsible for stable and controlled operation of the side window. The design intended by the vehicle manufacturer ensures:

• adequate system rigidity, limiting window vibrations and tilting during driving,
• cooperation with the factory control motor from the Window Regulators and Motors category,
• proper window guidance in the channels along the entire height of the door opening,
• maintenance of proper window pressure against the seals in the closed position.

A system configured in this way allows for comfortable use of the window from both the driver's side (via the control panel) and the rear passenger side, without the risk of jamming or excessive play.

Item Condition and Benefits of Choosing a Used Part

The offered regulator is a part in used condition, sourced from vehicle dismantling. Components of this type retain their factory geometry, original mounting points, and compatibility with the door's electrical system, which facilitates installation and reduces the risk of operational problems after replacement.

Choosing a used OEM part is cost-effective while maintaining the high quality of workmanship characteristic of the Audi brand. It is a sensible solution for window mechanism repairs, especially for daily-driven vehicles where functionality and fit to the existing door assembly are important.

Why Choose an Original Audi Window Regulator

Using an original regulator in the rear right door helps avoid problems typical of aftermarket parts, such as imprecise fit or the need for mounting modifications. The factory design ensures compatibility with other door components, including guides, the window, and seals.

This solution is particularly recommended for vehicle repairs where maintaining original functionality and user comfort is important – from the window mechanism's operation to noise reduction and proper door closing.
