This bulletin has undergone several revisions to expand its scope and update information:

• Revision 3: The current version, which revised the header to include additional models and model years.

Symptoms

Owners of affected Audi vehicles may observe that the variable glass roof flickers erratically. Additionally, the glass roof may become completely inoperable, preventing it from opening, closing, or adjusting as intended. The customer complaint is typically described as: "The variable glass roof flickers or cannot be operated."

No Associated Fault Codes

Unlike many vehicle malfunctions, Audi's workshop findings for this particular issue indicate that there is "No relevant entry in event memory." This means that diagnostic trouble codes (DTCs) are not typically stored in the vehicle's computer system for this specific problem, making diagnosis reliant on physical inspection and symptom reproduction.

Technical Background

Audi has identified two primary technical reasons for the glass roof flickering or inoperability:

1. Incorrectly Plugged Connectors: The connectors on the relevant control unit may not be properly seated or plugged in correctly.
2. Control Unit Deviation: The control unit J1288 may deviate from standard series production specifications.

Production Solution

To address these issues at the manufacturing level, Audi has implemented two solutions:

1. Employee Training: Instructions have been provided to production employees on how to correctly insert the connectors for the glass roof system.
2. Software Optimization: A software optimization for the J1288 control unit is expected to be released in November 2026 to improve its performance and reliability.

Repair Procedure Summary

If a customer complaint regarding the variable glass roof flickering or inoperability can be reproduced, technicians should follow these steps:

1. Lower the Headliner: The vehicle's headliner must be carefully lowered to gain access to the control units.
2. Check Connectors: Inspect all connectors on both control units associated with the glass roof system to ensure they are securely plugged in.
3. Control Unit Replacement: If all connectors are found to be correctly plugged in, and the complaint still persists, the control unit J1288 must be replaced. Figure 1 in the TSB visually highlights the location of control unit J1288 for technicians.
