2021-2024 Audi Panoramic Sunroof Seal Loose TSB 2063187/5

Symptoms

Owners of affected 2021-2024 Audi vehicles may experience one or a combination of the following issues related to a loose panoramic sunroof opening outer perimeter seal:

• Wind noise in the roof area, even when the sunroof panel is closed.
• Water dripping from the headliner area.
• A visibly distorted or non-flush sunroof opening perimeter seal with the roof panel.

Technical Background

Audi Technical Service Bulletin 2063187/5 explains that the adhesive bond of the panoramic sunroof opening perimeter seal to the roof panel can become compromised or fail entirely. This detachment, regardless of its degree, creates potential entry points for wind and water into the vehicle's cabin, leading to the symptoms described. Any detected detachment requires the replacement of the sunroof opening perimeter seal.

Diagnosis

To accurately diagnose the issue, technicians will perform a detailed inspection of the panoramic sunroof opening perimeter seal. This process involves:

1. Initial Inspection: The front sunroof glass panel is fully opened to allow access to the seal.
2. Adhesion Check: The technician will press the seal downwards and inwards with their fingers. The goal is to check for visible adhesive tape, which should be firmly attached. The foam adhesive tape must not appear stretched, loose, or detached from the roof panel.
3. Comprehensive Scan: This inspection is performed centimeter by centimeter along the entire length of the front sunroof opening. After completing the front, the sunroof panel is closed, and the rear portion of the sunroof opening perimeter seal is inspected using the same method.
4. Visual Cues: The TSB includes figures (5-8) that clearly illustrate examples of loose adhesive tape and gaps, which indicate detachment. Any area where the seal's adhesion is compromised or has failed is considered a potential entry point for water.

If any detachment is found during this inspection, the sunroof opening perimeter seal must be replaced.

Repair Procedure Summary

If a loose panoramic sunroof opening outer perimeter seal is identified, the repair procedure outlined in TSB 2063187/5 involves several key steps to ensure proper adhesion and function:

1. Seal Replacement: The existing, compromised perimeter seal is carefully removed.
2. Surface Preparation: Critical to the repair is the meticulous preparation of the adhesion surface. Technicians must follow explicit procedures detailed in ElsaPro to ensure the new seal bonds correctly and securely, preventing future detachment.
3. New Seal Installation: A new sunroof opening perimeter seal is installed onto the prepared surface.
4. End Stop Adaptation: Following reassembly, a sunroof panel and rollershade end stop adaptation must be performed. For most models, this is done using the sunroof panel and rollershade switches, with reference to TSB 2054505 for specific instructions. For Q4 e-tron models, this adaptation is carried out using a VAS tester in Guided Functions.
