Purpose and technical function

The presented weatherstrip moulding is a component designed for installation on the left side of the vehicle, within the area of the door with a side window. Its tasks include:

• draining water and debris from the window surface during raising and lowering,
• limiting moisture penetration into the door interior,
• stabilizing the window movement in the guide,
• improving the seal at the contact point between the window and the door panel.

Due to its design, which complies with Audi's factory standards, the moulding works with the window lifting mechanism and other door seals, ensuring the consistency of the entire system.

Benefits of using an original weatherstrip moulding

Using a component from the same production line as the factory equipment of the Audi TT allows for maintaining the correct window operating parameters and body tightness. Key advantages include:

• factory fit to the door profile – no need for modifications or adjustments to the shape,
• proper cooperation with existing seals and window fittings,
• maintaining the appropriate pressure against the window surface, which reduces cabin noise,
• preserving the aesthetic line of the window edge and door, without unnatural gaps.

For the user, this means stable window operation, a lower risk of the door interior fogging up, and more comfortable driving conditions, especially at higher speeds and in difficult weather conditions.

Application in service and repairs of the Audi TT 8S

Audi TT 8S FV Door Window Weatherstrip Moulding Strip Seal Left N/S will work well both for a typical replacement of a worn-out moulding and for more extensive body and paint work within the door area. The component is particularly useful when:

• scratches appear on the edge of the window caused by a worn moulding,
• an excessive amount of water gets inside the door,
• there is wind noise in the area of the upper door edge,
• it is necessary to restore factory tightness after door repairs.

Selecting the correct left-side weatherstrip moulding helps avoid problems with window geometry and ensures proper door closing without additional adjustments.
