2021-2025 Audi Q8/SQ8/RS Q8 Cloudy Rear Windows TSB

Audi has issued Technical Service Bulletin (TSB) 64 24 98 2062828/4 to address customer concerns regarding the appearance of rear side windows in certain Q8, SQ8, and RS Q8 models. This TSB, dated February 9, 2024, supersedes a previous bulletin, 23-96, from November 16, 2023, with updated information. The bulletin clarifies that a "milky/cloudy in appearance" on the rear side windows is not a fault.

Symptoms

Owners of affected Audi Q8, SQ8, and RS Q8 vehicles may observe that the "Rear door and/or side windows are cloudy/milky in appearance." This visual characteristic can be replicated by a technician, confirming the customer's observation.

Diagnosis

The "milky/cloudy in appearance" of the rear side windows is a visual characteristic that Audi has identified as normal for these models. This appearance is not consistent and can vary significantly depending on external factors such as the angle of the sun, the ambient lighting conditions, and the observer's perspective. When a customer reports this concern, a technician can typically replicate the visual effect, confirming the customer's observation. However, Audi's internal assessment, as detailed in TSB 64 24 98 2062828/4, confirms that despite this aesthetic, the windows fully comply with all series approval standards. This means the windows meet the rigorous quality and safety specifications established during the vehicle's development and production, and their optical properties are within the expected range for the materials and manufacturing processes used. Therefore, the presence of this milky or cloudy look does not indicate a material defect, structural issue, or any compromise to the window's functionality or durability.

Important Warnings for Owners

Audi has provided clear instructions regarding this condition:

• "Do not perform any repairs. Any repairs for this concern may be denied." This means that attempting to repair the windows for this appearance issue will not be covered under warranty and could result in charges to the owner.
• "Instruct the customer that this condition is normal and not a defect." Dealers are advised to inform customers that the milky or cloudy appearance is an expected characteristic of the windows.

What Owners Should Do

If you observe the milky or cloudy appearance on the rear side windows of your 2021-2025 Audi Q8, SQ8, or RS Q8, there is no action required. This condition is considered normal by Audi and does not indicate a defect or require repair. Do not attempt to have repairs performed, as they will not be covered under warranty. Instead, if you are concerned, you can discuss this TSB 64 24 98 2062828/4 with your authorized Audi dealership. They are instructed to inform customers that this is a normal characteristic of the vehicle's windows. This information helps prevent unnecessary service visits and ensures that owners are not charged for a condition that is part of the vehicle's standard design. The key takeaway is that your Audi Q8 cloudy rear windows are not indicative of a problem requiring intervention.
