2024-2025 Audi e-tron GT Electrical System Fault TSB

Owners of 2024-2025 Audi e-tron GT and RS e-tron GT vehicles may encounter a warning message in their instrument cluster: "Electrical system: fault. Please contact workshop". This message indicates a temporary restriction in the vehicle's electrical system, which can prevent the vehicle from being driven. Audi Technical Service Bulletin (TSB) 93 24 42 2075720/2 addresses this specific condition.

This TSB, issued on December 12, 2024, is Revision 2 and supersedes an earlier bulletin, Technical Service Bulletin Group 93 number 24-24 dated October 22, 2024. The revision updated the estimated time of arrival for the solution. This bulletin provides guidance to technicians and clarifies that this particular Audi e-tron GT electrical system fault does not require immediate component replacement.

Symptoms

When the ignition (terminal 15) is switched on, a yellow warning lamp illuminates in the instrument cluster. Concurrently, the message "Electrical system: fault. Please contact workshop" is displayed. In this state, the vehicle cannot be driven.

However, switching the ignition off and then back on typically clears the message. After this, the vehicle can be driven again without any restrictions. This intermittent nature is a key characteristic of the Audi e-tron GT electrical system fault described in this bulletin.

Technical Background

Audi has identified that certain customer usage behaviors can lead to a temporary restriction in the electrical system's function within a specific use case. This restriction triggers the warning message, temporarily preventing the vehicle from being driven.

Diagnosis & Fault Codes

During workshop investigations related to this condition, Audi has found that no relevant Diagnostic Trouble Codes (DTCs) are stored in the vehicle's systems. This indicates that the issue is not a traditional fault that generates a stored error code.

Important Warnings

Audi has provided specific instructions and warnings regarding this condition:

• "Do not replace any components for this condition since this will not resolve the customer's concern."
• This Technical Service Bulletin is for informational purposes only and is "not applicable to any Audi Warranty." This means that any attempts to repair this condition outside of the manufacturer's planned solution may not be covered under warranty.

Manufacturer's Solution & Timeline

Audi plans to implement an improved software solution for this electrical system issue. This software is scheduled to be integrated into production vehicles in Q3 2025. For existing vehicles, a solution is expected to be available by the end of the 1st quarter of 2025, though this timeline is subject to change.

What Owners Should Do

If you experience the "Electrical system: fault. Please contact workshop" message in your 2024-2025 Audi e-tron GT or RS e-tron GT, you should contact your authorized Audi dealer. Technicians are instructed to explain to customers that a solution is anticipated by the end of Q1 2025 and that no repairs are necessary at this point.
