2021 Audi Lineup Faint Windshield Images TSB

Owners of 2021 Audi vehicles, including the Audi e-tron, may notice faint images or residue on their windshields under certain lighting conditions. This issue, described as Audi e-tron windshield residue, is addressed by Technical Service Bulletin (TSB) 2047061/2, issued by Audi on April 9, 2020. This bulletin supersedes an earlier TSB, 17-40, and provides a specific procedure to resolve these cosmetic concerns.

Symptoms

The primary symptom described in the TSB is the appearance of faint images or residue on the inside of the windshield. These marks are often only visible under specific conditions, such as:

• At certain sunlight entry angles.
• When there is fog on the inside of the windshield.

The images can vary, appearing as afterimages from production stickers or marks left by suction cups used during the windshield installation process. This Audi e-tron windshield residue is a cosmetic issue stemming from manufacturing processes.

Fault codes / DTCs

This particular issue, involving faint images on the windshield, is not associated with any diagnostic trouble codes (DTCs). It is a visual anomaly rather than an electronic or mechanical malfunction that would trigger a fault code.

What the service bulletin says

Technical Service Bulletin 2047061/2 explains that the faint images or residue are caused by remnants from suction cups or labels used during vehicle production. This residue transfers to the glass and, while often invisible under normal conditions, becomes noticeable under certain lighting or moisture.

To remedy this, the TSB outlines a cleaning procedure using a specific cleaning cloth found in the window seal set, part number D 096330A2. Technicians are instructed to apply moderate pressure when cleaning and are specifically warned not to use the applicator included in the kit for this purpose. The service number for this procedure is 6414, with a damage code of 0030. The labor operation for cleaning residue from the inside of the glass is 6414 9999, estimated at 30 labor units.

Warranty coverage for this repair is applicable for vehicles up to 48 months or 50,000 miles. If your vehicle is outside this warranty period, the bulletin serves as informational guidance only.

What to do

If you own a 2021 Audi model and are experiencing Audi e-tron windshield residue or similar faint images on your windshield, it is recommended to contact your authorized Audi dealership. Explain the symptoms you are observing. The dealership service department can refer to TSB 2047061/2 to perform the appropriate cleaning procedure using the specified cleaning cloth and part number D 096330A2.
