2022-2025 Audi Virtual Cockpit Component Protection TSB

Audi has released Technical Service Bulletin (TSB) 00 24 95 2075586/1, dated October 11, 2024, to address a specific issue affecting the Audi virtual cockpit in certain 2022-2025 A3, S3, and RS 3 models. This bulletin highlights a condition where the Audi virtual cockpit component protection cannot be deactivated, leading to error messages and diagnostic trouble codes. This TSB is crucial for owners and technicians, as it provides guidance on a known problem that is currently under analysis by Audi.

Symptoms

Owners of affected Audi A3, S3, and RS 3 vehicles may notice that the virtual cockpit enters a component protection mode. This state prevents full functionality and can be accompanied by specific error messages. When this condition occurs, a workshop tester may display the message: "FAZ 9484 error: check sum 1 error". This indicates a problem with the component protection system's integrity check within the virtual cockpit, preventing its deactivation.

Fault Codes / DTCs

When the Audi virtual cockpit component protection issue is present, the following Diagnostic Trouble Code (DTC) may be stored in the Audi virtual cockpit (control unit J285, diagnostic address 0017):

• DTC U110100: Component protection active, active/static

This DTC specifically points to the component protection system being active and unable to be deactivated, which is the core of the problem described in TSB 00 24 95 2075586/1.

Diagnosis / Trigger Conditions

The component protection issue typically arises under specific circumstances related to vehicle programming. It occurs when a new gateway (diagnostic interface for data bus, J533, diagnostic address 0019) is programmed. The issue can also be triggered when the virtual cockpit itself (J285, diagnostic address 0017) undergoes programming. Following such programming, the Audi virtual cockpit component protection system engages and cannot be disengaged, indicating a conflict or an unfulfilled condition within the vehicle's security protocols.

Important Warnings and Manufacturer's Guidance

Audi has issued critical warnings regarding this issue, specifically advising against certain repair actions. The manufacturer states: "It is not necessary to replace the Audi virtual cockpit. Replacing the Audi virtual cockpit will therefore be charged back." This means that replacing the virtual cockpit will not resolve the underlying problem and will result in unnecessary costs for the owner or dealership. It is crucial to heed this warning to avoid incorrect repairs and charges.

Furthermore, Audi explicitly instructs technicians: "Do not attempt further repairs; please contact TAC and await further instructions." This guidance underscores that a definitive repair procedure is not yet available, and unauthorized attempts to fix the issue are discouraged.
