Symptoms

Owners of various Audi models, including the 2022-2026 Audi e-tron, may notice that their windshields are "streaked, has a snakeskin appearance, or its surface feels rough." This condition can impair visibility and affect the performance of the wiper blades.

Technical Background

The root cause of the "Audi e-tron streaked windshield" and similar issues across other Audi models is the accumulation of residue. This residue can stem from industrial fallout, normal road dirt, and grime, which adhere to the windshield surface.

Important Warnings

Audi Technical Service Bulletin 64 24 02 2020552/13 includes crucial advice for technicians and owners:

• "This procedure must be performed and verified before a wiper blade replacement. All Warranty claims will be rejected for wiper blade replacement if a defect is not found."
• "Do not use the 3M™ Glass Polishing Compound to clean the wiper blades."
• "Drying time is based on ambient temperatures. Temperatures of 60°F (15°C) or lower can extend drying time."

Repair Procedure Summary

To address the streaked windshield condition, Audi outlines a detailed, multi-step cleaning process:

1. Initial Cleaning: Begin by thoroughly washing and drying all affected exterior glass surfaces on the vehicle.
2. Wiper Service Position: Place the windshield wipers into their service position to allow full access to the glass.
3. Wiper Blade Cleaning: Use a household glass cleaner, such as Windex® or 3M™ Glass Cleaner, to clean any residue from the wiper blades themselves. It is important not to use the 3M™ Glass Polishing Compound on the wiper blades.
4. Compound Preparation: Shake the bottle of 3M™ Glass Polishing Compound (Part Number 60150) to ensure the product is mixed evenly.
5. Compound Application: Apply the polishing compound directly to the outside of the windshield, covering both the driver and passenger sides.
6. Polishing: Using a clean, dry 3M™ Microfiber Detail Cloth – Yellow (Part Number 39016), vigorously clean the windshield with long, horizontal strokes. Care should be taken to avoid applying the product to the window trim.
7. Drying Time: Allow the compound to dry on the windshield until a fine film layer, or haze, forms. Note that colder ambient temperatures (60°F or lower) may extend this drying time.
8. Rinsing: Rinse the windshield thoroughly with a garden hose. Also, rinse any polishing product that may have inadvertently been applied to the trim.
9. Final Drying and Buffing: With a fresh, clean, and dry microfiber cloth, dry and buff the glass to achieve a clear, streak-free shine.
10. Residue Removal: Finally, use a microfiber cloth dampened with warm water and wrung out to wipe off any remaining residue that might have come into contact with the trim or rubber seals.

This comprehensive cleaning process aims to eliminate the residue causing the "Audi e-tron streaked windshield" and restore clarity.
