Audi has released Technical Service Bulletin (TSB) 2080377/2, addressing an "on-board power system fault in cluster P000000 in the 008C" for certain 2022-2025 e-tron GT and RS e-tron GT models. This bulletin, revised on January 9, 2026, provides specific guidance to technicians on how to proceed when diagnosing this particular issue, which manifests as a warning light in the instrument cluster. The primary concern is an Audi e-tron GT on-board power system fault indicated by a specific Diagnostic Trouble Code.

Revision History

This Technical Service Bulletin has undergone the following revisions:

• Revision 1 (December 9, 2025): Initial publication of the TSB.
• Revision 2 (January 9, 2026): Revised the service procedure to include updated ODIS revision information.

Symptoms

Owners of affected vehicles may notice a prominent warning on their dashboard. The primary symptom reported by customers is the instrument cluster displaying either a "yellow or red warning fault." This visual alert indicates a potential issue with the vehicle's on-board power system, specifically the Audi e-tron GT on-board power system fault described in the TSB. Technicians are able to consistently duplicate this customer complaint during their workshop findings.

Fault Codes / DTCs

During diagnosis, technicians may find specific Diagnostic Trouble Codes (DTCs) stored in the vehicle's hybrid battery manager, identified as J840, which corresponds to address word 008C. The primary DTC associated with this issue is:

• P000000

Additionally, the TSB notes that "other miscellaneous DTC entries" may also be stored in the 008C address word, alongside P000000, indicating potential related issues within the hybrid battery manager.

Diagnosis and Reporting Obligation

When a customer reports an Audi e-tron GT on-board power system fault with a "yellow or red warning fault," technicians are instructed to follow a specific diagnostic and reporting protocol. First, they must verify that their diagnostic tester has no pending updates and that the ODIS diagnostic software version is at least 2025.12.05. This ensures that the diagnostic equipment is fully up-to-date for accurate troubleshooting and compliance with Audi's latest service procedures.

If the ODIS version is confirmed to be 2025.12.05 or newer, and the DTC P000000 is still present in the hybrid battery manager (J840, address word 008C), technicians are required to create a Technical Assistance Center (TAC) ticket. This ticket must be precisely labeled as "Reporting obligation according to the Technical Service Handbook- P000000 in 008C." This reporting step, outlined in TSB 2080377/2, is crucial for Audi to gather comprehensive data on the prevalence and specific characteristics of this particular fault, rather than providing an immediate repair solution.

Important Warnings

Owners should be aware of specific conditions outlined in this TSB:

• Warranty Coverage: This TSB is explicitly stated as "informational only and not applicable to any Audi Warranty." This means that any diagnostic or repair work related to this specific Audi e-tron GT on-board power system fault may not be covered under standard Audi warranty terms.
• Technician Action: The core of this TSB is a reporting obligation for technicians rather than a direct repair procedure. This indicates that Audi is currently collecting data on this specific fault, and a definitive repair solution or campaign may not yet be available or universally prescribed.

What Owners Should Do

If your 2022-2025 Audi e-tron GT or RS e-tron GT displays a "yellow or red warning fault" in the instrument cluster, particularly if you suspect an Audi e-tron GT on-board power system fault or have had the vehicle scanned to reveal DTC P000000, it is advisable to contact your authorized Audi service center. Inform them about the symptoms you are experiencing and specifically mention Technical Service Bulletin 2080377/2. While this TSB is informational and not covered by warranty, bringing it to your dealer's attention ensures that the issue is properly documented and reported to Audi, contributing to a potential future resolution.
