2021-2023 Audi Sunroof Frame Modification TSB

Owners of certain 2021-2023 Audi models may experience issues with their sunroofs not closing correctly after a replacement of the front sunroof glass panel or sunroof frame. This is addressed by Audi Technical Service Bulletin (TSB) 60 22 59 2065731/2, which details a required modification to ensure proper function.

This TSB, dated May 6, 2022, supersedes an earlier bulletin, 60 22-58 dated January 8, 2022, to include additional model years. The issue stems from a change in the development of the sunroof assembly, meaning that current replacement components might require a specific modification for compatibility.

Symptoms

Owners may notice that the front sunroof glass panel does not close completely or smoothly after it has been replaced. This occurs because a component called the water guidance washer, located on the sunroof mechanism pivot, protrudes too much. This protrusion, along with the rubber 'skirt' on the front glass panel, creates interference with the sunroof opening.

Diagnosis / Trigger Conditions

This issue typically arises when the front sunroof glass panel or the sunroof frame needs to be replaced for any reason. The interference between the water guidance washer and the glass panel's rubber skirt prevents the sunroof's closing sequence from completing. Technicians will identify this by observing the deformation of the front sunroof glass panel's side skirt due to the protruding washer.

Repair Procedure Summary

The repair involves a precise modification to the water guidance washer. First, the front sunroof glass panel must be removed. Then, using a small pair of diagonal cutters, the water guidance washer is trimmed back. The goal is to ensure the washer protrudes no further than the pivot pin. This operation must be performed on both sides of the sunroof mechanism.

After the modification, the front sunroof glass panel is reinstalled and adjusted according to Audi's specifications. This includes setting the sunroof panel and rollershade end stop adaptation using the vehicle's switches. Technicians are also instructed to refer to TSB 2054505, titled "60 Sunroof glass panel or sunroof rollershade do not operate," for additional guidance on this process.

Required Tools or Parts

The primary tool required for this modification is a small pair of diagonal cutters, also known as side cutters. No specific replacement parts are listed for the water guidance washer itself, as the existing component is modified.

Important Warnings

• Exercise extreme caution during the modification procedure 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.
• Completely remove all plastic fragments created from trimming the water guidance washer. Any stray plastic fragments left behind can cause permanent damage to the sunroof frame mechanism. A vacuum cleaner may be used to ensure thorough removal.

Warranty Information

This repair falls under Claim Type 110 and is covered for up to 48 months or 50,000 miles, whichever comes first. All warranty claims must adhere to the Audi Warranty Policies and Procedures Manual.

Owner Action

If you own a 2021-2023 Audi Q3, Q7, Q8, SQ7, SQ8, RS Q8, or e-tron model and are experiencing issues with your sunroof closing after a recent replacement, or if your sunroof frame or glass panel needs replacement, you should contact your authorized Audi dealership. They are aware of this Technical Service Bulletin and can perform the necessary Audi e-tron sunroof frame modification to ensure your sunroof operates correctly.
