Symptoms

Owners of affected 2021 Audi vehicles may notice that when the turn signal is activated, the sound emitted from the internal speaker of the virtual cockpit is intermittently very loud. When this occurs, the volume is approximately twice as loud as usual, which can be distracting and unexpected.

Technical Background

This issue, leading to an Audi virtual cockpit loud turn signal, stems from a software anomaly within the Virtual Cockpit system. There is no physical defect with the hardware; the problem is purely software-related.

Repair Procedure Summary

To correct the Audi virtual cockpit loud turn signal issue, a software update for the Virtual Cockpit control unit (-J285-, address word 0017) is required. This update is performed using the Service Vehicle Management (SVM) system with the SVM code FPKWW0060. The process involves several steps:

1. Prepare ODIS: Deactivate Bluetooth or Wi-Fi connections in ODIS and ensure DoIP (Diagnostics over Internet Protocol) is turned ON. To activate DoIP, navigate to Administration>>General>>GFF Process>>DoIP communication>>Only allow DoIP communication. Note that this setting resets after the diagnostic session ends.
2. Connect Diagnostics: Connect the diagnostic head to the vehicle using a USB cable.
3. Initiate Flash: Open the "Flash" feature in ODIS and select "SVM code input."
4. Enter SVM Code: Input the SVM code FPKWW0060.
5. Prepare USB Stick: Ensure a USB stick containing the update software is connected. The SD creator part number for this software is 8W6 906 961 Q.
6. Maintain Power: Keep the vehicle key on the reader coil throughout the update process.
