2022-2023 Audi Virtual Cockpit Loud Turn Signal TSB

Symptoms

Owners of certain 2022-2023 Audi models may experience an Audi loud turn signal sound. The primary symptom is that the "clicking sound is audible when the turn signal is active and is sporadically unusually loud." This issue specifically affects the Virtual Cockpit system. It's important to note that no relevant Diagnostic Trouble Codes (DTCs) are stored in the vehicle's system when this condition occurs.

Diagnosis

Audi has identified that the unusually loud turn signal sound is caused by a software-related issue within the Virtual Cockpit. This means the problem is not due to a faulty hardware component but rather an anomaly in the system's programming. Optimized software has already been implemented in current series production vehicles to prevent this issue.

Important Warning

When your vehicle's instrument cluster is being updated, it is critical to follow a specific procedure. Audi states: "When updating the instrument cluster, the vehicle key must be placed on top of the emergency key reader coil for the duration of the update."

Repair Procedure Summary

To resolve the Audi loud turn signal issue, a software update for the Instrument Cluster is required. This procedure, outlined in Technical Service Bulletin 90 23 93 2069280/1, involves using specialized diagnostic equipment and software. The update can be performed using either an automated method via ODIS Tester or a manual method if there are SVM code or server issues. The update process takes approximately 30-60 minutes, including 20-50 minutes for the software update itself and an additional 10 minutes for SVM work.
