2021-2022 Audi Sunroof Frame Modification TSB

Symptoms

Owners of 2021-2022 Audi Q3, Q8, and e-tron vehicles may experience issues with their sunroof, specifically concerning the "front sunroof glass panel closing sequence from completing." This can manifest as interference that prevents the sunroof from closing fully or correctly. The problem typically arises after the front sunroof glass panel or sunroof frame has been replaced.

Technical Background

Audi has identified that the design of the sunroof assembly has evolved over time. When replacement components, such as the sunroof frame and front sunroof glass panel, are installed, they may not be fully compatible with the existing assembly without a slight modification. This incompatibility leads to the interference that prevents proper sunroof operation.

Important Warnings

• If your vehicle is outside of its warranty period, this Technical Service Bulletin (TSB) is for informational purposes only, meaning the repair may not be covered by Audi.
• During the modification procedure, extreme caution must be exercised to avoid scratching or damaging the surrounding metal components of the sunroof frame and lifting mechanism. It is recommended to surround the area being modified with masking tape if necessary.
• All plastic fragments created from trimming the water guidance washer must be completely removed. Use a vacuum cleaner to ensure no debris remains, as stray plastic fragments can cause permanent damage to the sunroof frame mechanism.

Repair Procedure Summary

This TSB outlines a modification process for the sunroof frame to ensure compatibility with replacement sunroof components. The core of the issue is a protruding water guidance washer on the sunroof mechanism pivot, which causes the rubber "skirt" on the front glass panel to interfere with the sunroof opening, preventing the "front sunroof glass panel closing sequence from completing."

The repair involves the following steps:

1. Preparation: The front sunroof glass panel must be removed to access the water guidance washer. Technicians should refer to the workshop manual for proper removal procedures.
2. Modification: Using a small pair of diagonal cutters (side cutters), the water guidance washer on the sunroof mechanism pivot must be carefully trimmed. The washer should be cut back so that it protrudes no greater than the pivot pin. This operation needs to be performed on both sides of the mechanism.
3. Cleanup: After trimming, it is crucial to ensure all plastic fragments are removed from the area using a vacuum cleaner to prevent future damage to the sunroof mechanism.
4. Reinstallation and Adjustment: The front sunroof glass panel is then reinstalled and adjusted according to specifications found in ElsaPro. Following reassembly, the sunroof panel and rollershade end stop adaptation must be set using the sunroof panel and rollershade switches. For instructions on this, technicians should refer to TSB 2054505, titled "60 Sunroof glass panel or sunroof rollershade do not operate."

This modification ensures that the replacement sunroof components, including the front sunroof glass panel, can be installed without interference, resolving the Audi e-tron sunroof closing problem.

Required Tools

• Diagonal cutters (side cutters)
