2021-2023 Audi Q3, Q5, Q7, Q8, e-tron Sunroof Seal TSB

Owners of 2021-2023 Audi Q3, Q5, Q7, Q8, and e-tron vehicles may experience issues with the panoramic sunroof opening perimeter seal. This Technical Service Bulletin (TSB) 2063187/1 from Audi outlines the symptoms and the necessary repair procedure for a loose sunroof seal.

Symptoms

If you own a 2021-2023 Audi and notice any of the following, your vehicle may be affected by a loose sunroof perimeter seal:

• "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 occur because the adhesion of the sunroof opening perimeter seal to the roof panel may be compromised or have failed completely. Even a minor detachment can allow wind and water to enter the cabin, leading to the issues described. This is a common problem for an Audi e-tron sunroof seal loose.

Diagnosis / Trigger Conditions

To diagnose a loose sunroof perimeter seal, a technician will perform a detailed inspection:

1. The front sunroof glass panel is fully opened to allow access to the seal.
2. The technician will press the seal downwards and inwards with their fingers to check for visible adhesive tape. The foam adhesive tape should not be loose or detached from the roof panel.
3. This inspection is repeated centimeter by centimeter along the entire length of the front sunroof opening.
4. The rear portion of the sunroof opening perimeter seal is also checked for adhesion.
5. Clear evidence of detachment includes color and shape differences at the contact point, revealing gaps where the adhesive tape has come loose from the vehicle body. Any compromised adhesion, no matter how small, indicates a need for repair.

Repair Procedure Summary

The primary solution for an Audi e-tron sunroof seal loose is the replacement of the sunroof opening perimeter seal. The repair involves several steps to ensure proper adhesion and functionality:

1. Inspection: As detailed above, the technician thoroughly inspects the entire sunroof perimeter seal for any signs of detachment or compromised adhesion.
2. Seal Replacement: If any detachment is found, the sunroof opening perimeter seal must be replaced. This involves carefully removing the old seal.
3. Surface Preparation: Critical to a lasting repair, the adhesion surface must be meticulously prepared. This includes cleaning the area with a specified surface preparation solvent and applying an adhesion promoter.
4. New Seal Installation: The new sunroof perimeter seal is then installed, ensuring proper and complete adhesion to the roof panel using specialized tools like a roller.
5. Adaptation: After reassembly, the sunroof panel and rollershade end stop adaptation must be set using the appropriate switches. This step may require referring to TSB 2054505, "60 Sunroof glass panel or sunroof rollershade do not operate," for specific instructions.
