Purpose and function of the component

The rear right quarter window in an Audi A4 B8 is responsible for illuminating the rear part of the cabin and stabilizing the side zone of the body. As a fixed element, it works with the door frame or side structure, ensuring:

• proper structural stiffening in the rear pillar area,
• a visually consistent window line,
• maintenance of the seal and window system integrity in the rear part of the vehicle.

By maintaining the factory shape and glass thickness, the window supports proper aerodynamics and reduces air turbulence around the rear part of the body.

Technical parameters and AS2 glass standard

The AS2 marking indicates the use of glass with appropriate light transmittance, in accordance with the requirements for side and rear windows. This type of glass provides:

• an appropriate level of transparency for the driver and passengers,
• compliance with safety standards regarding impact resistance,
• controlled breakage characteristics in the event of a collision.

The vehicle placement defined as rear – right side allows for unambiguous matching of the element to the correct mounting position, which is crucial when planning body and glass repairs.

Benefits of using original Audi glass

Using an original quarter window in an Audi A4 B8 allows for maintaining consistency with other glazing elements. The main advantages include:

• factory fit to the bodywork – proper adhesion to the frame and seals,
• stable seating in the mounting point, reducing glass stress,
• maintaining uniform window optics on one side of the vehicle,
• easier service work during installation due to predictable dimensions and shape.

For the user, this means a lower risk of leaks, rattles, or unwanted noises resulting from improper component fitment.

Condition of the part and use in repairs

The presented window comes from a group of used original parts, which allows for combining reasonable repair costs with maintaining the manufacturer's specifications. This type of part is particularly suitable in situations where:

• the side window has been damaged as a result of a collision or vandalism,
• it is necessary to replace the element after bodywork in the rear part of the vehicle,
• there is a need to restore the factory appearance of the vehicle after previous non-factory modifications.

Choosing an original, used window is often a beneficial solution for drivers who want to maintain compliance with the manufacturer's design while optimizing the repair budget.

Integration with other body components and additional information

The rear right quarter window works with seals, trim strips, and the rear pillar structure, so when planning a repair, it is worth paying attention to the condition of these components. If you are considering a comprehensive replacement of glazing or other body parts, it may be helpful to browse the entire category of the guide to the most frequently chosen used original parts for popular car models to better plan the scope of work and select the appropriate components.
