2022-2023 Audi e-tron GT 'Maneuver assist: fault' TSB

Owners of 2022-2023 Audi e-tron GT and RS e-tron GT vehicles may occasionally encounter an instrument cluster message stating, "Maneuver assist: fault. Please contact service." This issue, documented in Technical Service Bulletin PSS 91 (91 21 48 2064985/1), points to a software timing problem rather than a hardware malfunction. While the message is briefly displayed, the maneuver assist system continues to function normally after it disappears.

Symptoms

The primary symptom is the brief appearance of the message "Maneuver assist: fault. Please contact service" on the instrument cluster. This warning typically shows up shortly after the vehicle is started. The message then disappears within a few seconds, and the maneuver assist system operates as expected without any further issues. This condition is sporadic, meaning it does not occur every time the vehicle is started.

Fault Codes / DTCs

Audi has confirmed that there are no relevant Diagnostic Trouble Codes (DTCs) stored in the driver assist systems control module, identified as J1121 (address word 00A5), when this "Audi e-tron GT maneuver assist fault" occurs. This absence of DTCs helps confirm that the issue is not a typical system malfunction but rather a software anomaly.

Diagnosis

The technical background provided by Audi indicates that the "Audi e-tron GT maneuver assist fault" message is caused by a timing issue within the vehicle's software. This software glitch briefly triggers the warning message, even though the maneuver assist system itself is fully functional. Workshops have confirmed the sporadic nature of the concern and the lack of associated DTCs.

Important Warnings

Audi explicitly states the following regarding this condition:

• "Do not replace any components for this condition since this will not resolve the customer's concern."

This means that technicians should not attempt to replace parts to fix the "Maneuver assist: fault" message, as it will not provide a solution and could lead to unnecessary costs or delays. The root cause is software-related, not hardware.

Workaround

While a permanent software fix is being developed, owners can temporarily prevent the "Maneuver assist: fault" message from appearing by deactivating the maneuver assist feature. This can be done through the vehicle's infotainment system by navigating to:

• Car >> Parking aid >> Maneuver assist

Alternatively, if the parking aid is active, select >> Maneuver assist. It's important to note that these settings are linked to individual myAudi user accounts, so each user may need to adjust this setting separately if they wish to avoid the message.

Manufacturer's Remedy

Audi is actively working on a software solution to address the "Audi e-tron GT maneuver assist fault." A permanent fix is currently under development and is anticipated to be available in the third quarter of 2023. This Technical Service Bulletin (91 21 48 2064985/1) will be updated once more information regarding the solution is released.
