- stable window guidance throughout its full range of motion,
- even load distribution to the guides,
- compatibility with the factory window control system in the rear doors,
- operation under typical passenger car operating conditions.
The part is designed as part of the Audi window system, which helps maintain factory operating parameters – both in terms of window speed and its positioning within the seals.
Part Condition and Benefits of Choosing a Used Part
The window regulator is offered as a used part, allowing for an economical repair of the window system while maintaining the original manufacturer's specifications. Choosing a used OEM part for Audi is a solution that often combines:
- lower cost compared to a new aftermarket part,
- retention of factory design and fit,
- reduced risk of installation issues arising from dimensional differences.
For users planning more extensive repairs or upgrades to drivetrain and control systems, it may also be valuable to consult a guide on selecting used components – especially regarding OEM markings and verification procedures.

- vehicle placement (rear, right side),
- compatibility with the factory window control system,
- the correct type of mountings for the door structure.
A correctly selected part allows for installation without altering the door structure, which reduces labor time and minimizes the risk of additional damage. If you have any doubts during selection, it is advisable to refer to the manufacturer's markings and catalog data to ensure full compatibility with your specific vehicle configuration.
