• Seamless integration with the existing window regulator and door hardware.
• Reduced risk of window jamming, misalignment, and uneven movement.
• Restoration of proper mechanism function after a collision, wear, or previous unsuccessful repair.

This solution is particularly beneficial when you want to maintain the original window operation characteristics and ensure even door closing.

Characteristics of a Used Part

The offered guide is a used part, sourced from disassembly, allowing for a reasonable cost while preserving the original Audi construction. This type of part is a good choice when you want to:

• reduce repair costs while retaining an OEM component,
• avoid fitting issues typical of cheaper aftermarket alternatives,
• maintain technical consistency within the window mechanism throughout the vehicle.

Before installation, a standard inspection of the regulator mechanism and the condition of the guides on the opposite side is recommended to ensure uniform operation of both rear windows.
