Purpose and function of the seal

The presented seal is dedicated to the rear left side window in the door, meaning its geometry, rubber profile, and mounting method are optimized for a specific area of the body. As a result, the component works correctly with the window lifting mechanism and the door frame, ensuring:

• stable vertical window guidance,
• reduction of vibrations and rattling while driving,
• sealing of the window edge against the door panel.

Benefits of using an original Audi seal

The original rubber seal for the side window in an Audi has been designed to maintain factory standards of tightness and comfort. Using this component allows you to:

• reduce wind noise at higher speeds,
• limit moisture penetration into the door interior,
• maintain proper pressure of the window against the frame, which promotes the durability of the lifting mechanism.

Thanks to the preservation of the original geometry, installation proceeds in a predictable manner, without the need for modifications to the door or guides, and the fitment to the body remains consistent with the manufacturer's specifications.

Material and operational characteristics

The seal is made of flexible rubber material selected for resistance to typical operational loads: temperature changes, UV radiation, and contact with water and road debris. Such material configuration promotes the maintenance of:

• proper flexibility of the edges adhering to the window,
• dimensional stability over a long period of use,
• a uniform contact line with the window and door frame.

The item comes from dismantling, which in practice means it is an original Audi part with parameters consistent with factory design assumptions, while simultaneously providing an economical solution for repair or restoring the seal in the rear side window area.

Selection and installation in the rear left body area

The seal is intended for installation in a specific location on the vehicle – the rear left door – which facilitates the identification of the correct component during repair. When selecting, it is worth paying attention to:

• compatibility of the installation side (rear, left),
• intended use for the side window in the door,
• belonging to the Window seals and trims group.

A correctly selected seal helps avoid problems with window closing, leaks at the contact point with the door frame, and unwanted noises while driving, which is important for both comfort and the durability of other elements in this area.
