2025 Audi A5 / A6 e-tron Glass Roof Flickers TSB 2079213/2

Revision History

Technical Service Bulletin 2079213/2 was initially published on September 9, 2025, as Revision 1. Revision 2, released on September 25, 2025, included a revised header to add additional models to the scope of the bulletin.

Symptoms

Owners of affected 2025 Audi A5 and A6 e-tron vehicles may observe that the variable glass roof flickers or cannot be operated. The specific customer complaint noted is: "The variable glass roof flickers or cannot be operated." This issue impacts the functionality of the sliding/tilting sunroof or panorama roof actuator, leading to intermittent operation or complete failure.

Technical Background

Audi Technical Service Bulletin (TSB) 2079213/2 identifies two primary reasons for the glass roof malfunction. Firstly, the connectors on the control unit may not be plugged in correctly, leading to poor electrical contact. Secondly, the control unit J1288 itself might deviate from standard series production specifications, indicating a potential manufacturing defect. Workshop findings typically show no relevant entry in event memory, meaning no diagnostic trouble codes (DTCs) are stored, making the customer's direct observation of the Audi A5 roof flickers or inoperability the primary diagnostic indicator.

Diagnosis and Trigger Conditions

To diagnose the issue, technicians should first attempt to reproduce the customer's complaint regarding the glass roof flickering or inoperability. If the condition is confirmed, the next step involves a physical inspection. The headliner must be lowered to gain access to the roof system's components. Technicians will then check whether all connectors on both control units associated with the glass roof system are securely and correctly plugged in.

Repair Procedure Summary

For vehicles exhibiting the Audi A5 roof flickers symptom, the repair process outlined in TSB 2079213/2 involves a two-step approach:

1. Reproduce Complaint and Initial Check: If the customer complaint can be reproduced, the headliner must be lowered to access the roof system components.
2. Connector Inspection and Securing: Technicians must then check whether all connectors on both control units are plugged in correctly. This ensures proper electrical contact and functionality.
3. Control Unit Replacement (if necessary): If, after ensuring all connectors are properly seated, the complaint still occurs, control unit J1288 must be replaced. Figure 1 in the TSB illustrates the location of control unit J1288, highlighted as item number 8, guiding technicians to the correct component for replacement.

Audi notes that a software optimization for control unit J1288 is expected in November 2026, which may address future production issues, but current repairs focus on the physical connections and component replacement.
