Purpose and Function of the Part

The presented window frame seal operates in the rear left part of the body, in the passenger door area. Its function is to stably guide the window in its tracks and cooperate with the window lifting and lowering mechanism. Thanks to its appropriate profile, it limits window vibrations, reduces the risk of it becoming crooked, and supports the proper operation of the entire system.

The part belongs to the group of Window Regulators and Motors, meaning it is directly related to the functioning of the window opening mechanism, not just the body's aesthetics. Replacing a worn or damaged sealing frame often helps eliminate problems with a stiff window, unpleasant creaking noises, or leaks during rainfall.

Benefits of Using an Original Seal Frame

Using an original component for Audi translates into several significant operational advantages:

• precise fit to the shape of the door and window in the Audi A6 C6,
• stable cooperation with the factory window regulator and motor,
• reduction of air drafts and noise in the cabin,
• reduced risk of the window jamming in extreme positions.

Thanks to this, you restore the proper operation of the rear left window without the need to interfere with other door components. This is particularly important for vehicles used daily, where acoustic comfort and body sealing have a direct impact on driving comfort.

Characteristics and Condition of the Part

The offered seal frame is a used part from a dismantled vehicle. Such components retain their factory geometry and mounting method, which facilitates installation and helps avoid problems typical of aftermarket parts with poorer dimensional tolerances. A used part is a sensible choice for drivers who want to keep their car in good technical condition at a controlled cost.

The seal is intended for installation in the rear left part of the vehicle, which eliminates the risk of choosing the wrong side. The vehicle placement has been clearly defined, making it easy to verify compatibility with your car's configuration before purchase.

Selection by Numbers and Technical Support

When selecting body parts and window mechanisms for Audi, it is particularly important to use manufacturer markings and reference numbers. This helps avoid discrepancies arising from differences between model years, equipment versions, or changes made during production. If in doubt, it is worth consulting the VIN number and service documentation.

Complementary Parts from the Same Group

If you are planning a comprehensive repair or upgrade of the window area in your Audi and need other parts from the same group, such as guides, lifting mechanisms, or control motors, check the available parts in the category Audi Window Regulators and Motors.

For larger service jobs, it is also worth paying attention to seasonal loads on the body and seals. In low temperatures, rubber and plastic parts are particularly susceptible to hardening and cracking.
