Purpose and fitment

The window has been designed specifically for the Audi A7 4G8 generation body, taking into account the characteristic side line and door shape. Its placement in the front – left side of the vehicle zone guarantees compatibility with factory seals, guides, and the window regulator mechanism. As a result, proper regulator operation and sealing against water and noise are maintained after installation.

Technical characteristics of the AS2 glass

The AS2 marking indicates a window with enhanced performance parameters compared to basic non-tempered glass. This type of glass provides:

• appropriate light transmittance in accordance with requirements for side windows,
• controlled mechanical strength against impacts typical for road use,
• safe material behavior in the event of damage.

Thanks to this, the window fits well with the passive safety and driving comfort requirements in premium class cars, such as the Audi A7.

Benefits of using an original Audi window

Using an original component from the Car windows category allows you to maintain the stylistic and technical consistency of the entire side of the body. Key advantages include:

• Factory fitment – the correct shape and bending radii of the glass, which facilitates installation and reduces the risk of leaks.
• Compatibility with door equipment – proper cooperation with guides, seals, and the lifting mechanism.
• Optical consistency – maintaining a uniform appearance of the glazing on the driver's side relative to the other windows.

This is particularly important during post-collision repairs, when the goal is to restore the original body parameters without compromising functionality.

Use in repairs and upgrades

The front left door side window will work well both for typical replacement of damaged glass and for more extensive bodywork and paint repairs on the driver's side. Replacing with an original component allows you to:

• restore correct visibility and driving comfort,
• maintain the body line consistent with the manufacturer's design,
• reduce the risk of problems with door closing and window regulator operation.

• check the condition of the door guides and seals,
• verify the correct setting of the window regulator mechanism,
• thoroughly clean the contact surface of the glass with the seals.
