2017-2024 Audi Panoramic Sunroof Seal Wind Noise TSB

Owners of certain 2017-2024 Audi vehicles may experience issues with their panoramic sunroof, including noticeable wind noise or water leaks. This Technical Service Bulletin (TSB) 2063187/4, issued on October 9, 2023, provides detailed information and repair procedures for addressing a loose Audi panoramic sunroof seal. This bulletin supersedes TSB Group 60 number 23-64 dated March 31, 2023.

Revision History

This TSB has undergone several revisions to refine its scope and warranty information:

• Revision 4 (Current): Revised warranty to generalize SRTs (Standard Repair Times) across all models.
• Revision 3 (March 31, 2023): Revised the header to add Q4 e-tron and Q4 Sportback e-tron models, and updated warranty details for these additions.
• Revision 2 (January 9, 2023): Revised warranty information with an updated Labor Operation.

Symptoms

If your vehicle is affected by this issue, you might observe one or a combination of the following symptoms:

• "They hear wind noise in the roof area with the sunroof panel closed."
• "They have seen water drip from the headliner area."
• "The sunroof opening perimeter seal is distorted and/or not flush with the roof panel."

These symptoms indicate that the adhesion of the sunroof opening perimeter seal to the roof panel may be compromised or have failed, creating potential entry points for wind and water into the cabin.

Technical Background and Diagnosis

The underlying cause is compromised or failed adhesion of the sunroof opening perimeter seal to the roof panel. Any degree of detachment can lead to the reported symptoms. Any detachment found during inspection must be corrected by replacing the sunroof opening perimeter seal.

Technicians will inspect the Audi panoramic sunroof seal for any signs of detachment or distortion. The inspection process involves:

1. Fully opening the front sunroof glass panel (as shown in Figure 1: Front sunroof panel open).
2. Pressing the seal downwards and inwards with fingers until the adhesive tape is visible (Figure 2: Checking the adhesion quality). The foam adhesive tape should not be loose or detached, even if stretched. Figure 3 illustrates a properly adhered perimeter seal.
3. Repeating this procedure centimeter by centimeter over the entire length of the front sunroof opening. After completing the front, the panel is closed.
4. Using the same inspection principle, checking the seal adhesion in the rear portion of the sunroof opening (Figure 4: Begin inspection of the rear portion of the perimeter seal).

Figures 5 through 8 provide clear visual examples of detachment, showing loose adhesive tape, obvious color and shape differences, and gaps that reveal compromised adhesion.

Repair Procedure Summary

If any adhesion compromise or failure is found, the sunroof opening perimeter seal must be replaced. The repair procedure emphasizes following the instructions in ElsaPro explicitly, paying particular attention to the adhesion surface preparation. The locations where adhesion is compromised are potential entry points for water into the cabin, even if outside the sunroof drainage area.

After reassembly, technicians must perform an adaptation of the sunroof panel and rollershade end stops using the vehicle's switches. For detailed instructions on this adaptation, technicians are directed to refer to TSB 2054505, titled "60 Sunroof glass panel or sunroof rollershade do not operate."
