2022-2023 Audi Models Streaked Windshield TSB

Symptoms

Owners of 2022-2023 Audi models may notice that their windshield is streaked, has a distinct snakeskin appearance, or feels rough to the touch. These visual and tactile issues can impair visibility and detract from the driving experience.

Technical Background

According to Audi, the primary cause of an Audi streaked windshield or rough surface is the accumulation of residue. This residue can originate from industrial fallout, which consists of fine particles released into the atmosphere by industrial processes, as well as common road dirt and grime encountered during daily driving. Over time, these contaminants bond to the glass surface, leading to the observed symptoms.

Important Warnings

Audi emphasizes specific conditions related to this service procedure:

• Wiper Blade Warranty Claims: This cleaning procedure must be performed and verified before any wiper blade replacement. All warranty claims for wiper blade replacement will be rejected if a defect is not found after this cleaning. This prevents unnecessary parts replacement if the issue is merely surface contamination.
• Product Usage: Do not use the 3M™ Glass Polishing Compound to clean the wiper blades themselves. This product is intended for the glass surface only.

Repair Procedure Summary

This Technical Service Bulletin (TSB 2020552/11) outlines a detailed 10-step process for cleaning the exterior glass to eliminate streaking and roughness:

1. Preparation: Thoroughly wash and dry all affected exterior glass surfaces on the vehicle.
2. Wiper Service Position: Place the windshield wipers in the service position (Figure 1 in the TSB illustrates this position).
3. Wiper Blade Cleaning: Using a household glass cleaner, such as Windex® or 3M™ Glass Cleaner, clean any residue from the wiper blades (Figure 2 shows a technician cleaning the blades).
4. Compound Preparation: Shake the bottle of 3M™ Glass Polishing Compound (Part No. 60150) vigorously to ensure the product is evenly mixed (Figure 3 displays the product bottle).
5. Compound Application: Apply the cleaner directly to the outside of the windshield, covering both the driver and passenger sides (Figure 4 shows the cleaner applied to the glass).
6. Vigorous Cleaning: Use a clean, dry microfiber cloth, such as the 3M™ Microfiber Detail Cloth - Yellow (Part No. 39016), to vigorously clean the windshield. Use long, horizontal strokes (Figure 5 shows the cloth, and Figure 6 demonstrates the horizontal cleaning motion). Technicians are advised to avoid applying the product to the window trim.
7. Drying Time: Allow the windshield to dry until a fine film layer, or haze, forms on the glass. Drying time may vary based on ambient temperatures; temperatures of 60°F (15°C) or lower can extend this time.
8. Rinsing: Use a garden hose to thoroughly rinse the windshield. Also, rinse any product that may have inadvertently been applied to the trim (Figure 7 illustrates the rinsing process).
9. Drying and Buffing: With a separate clean, dry microfiber cloth, dry and buff the glass to achieve a clean, streak-free shine (Figure 8 shows the drying step).
10. Final Wipe: Use a microfiber cloth, wet with warm water and wrung out, to wipe off any remaining residue that may have contacted the trim or rubber components.
