2022 Audi e-tron GT Software Update for HV & HUD Issues

Symptoms

Owners of certain 2022 Audi e-tron GT vehicles may experience two distinct issues related to unfavorable software configurations. The first symptom involves the vehicle's high-voltage system. After an under-voltage event in the 12 Volt electrical system—such as a drained battery from showroom use—the "high-voltage system cannot be restarted after under-voltage". This can prevent the vehicle from operating.

The second issue concerns the head-up display (HUD). Drivers might notice "Vibrations may occur in the head-up display". These vibrations are also attributed to an unfavorable software configuration that affects the control of the step motor, which can lead to a restricted visible area within the head-up display.

Diagnosis / Trigger Conditions

Both identified issues stem from specific software configurations within the vehicle's control modules. For the high-voltage system restart problem, the primary trigger is an under-voltage condition in the 12-volt electrical system. This can happen if the 12V battery drains, for example, during extended periods of vehicle display or showroom use. The existing software configuration prevents the high-voltage system from properly recovering and restarting after such an event.

The head-up display vibrations are directly linked to an unfavorable software configuration that governs the step motor. This software issue causes the motor to operate incorrectly, leading to visible shaking or flickering in the projected display. This can impair the driver's ability to clearly see information presented on the head-up display, restricting its effective area.

Repair Procedure Summary

Audi has issued a service package, identified as Update 9308, to correct these software-related issues. The repair involves updating the software for two specific control modules: the Hybrid Battery Management Control Module (-J840-) and the Head-Up-Display Control Module (-J898-). This Audi e-tron GT software update is designed to resolve the underlying software configurations causing the high-voltage system restart failure and the head-up display vibrations.

Dealerships are instructed to access repair instructions through ELSA/ServiceNet. Crucially, this update requires no new parts allocation, indicating it is a software-only solution. Dealers must check their daily campaign open inventory reports or Order Management Data (OMD) to identify all affected vehicles currently in their inventory. It is mandatory for every affected vehicle to receive this software update before it is delivered to consumers.

Important Warnings

Audi explicitly states that this action is a vehicle UPDATE, not a recall. This distinction is important for owners to understand, as the notification and resolution process may differ from a traditional safety recall.

Furthermore, Audi has issued a critical directive to dealerships: "Please ensure that this UPDATE is performed on every applicable vehicle before delivery to consumers." This means that any new or used 2022 Audi e-tron GT vehicle in dealer inventory that is affected by this issue must have the software update applied before it can be sold or delivered. In total, 1,039 vehicles in the U.S. and 215 vehicles in Canada are affected by this update.

Owner Action

If you own a 2022 Audi e-tron GT and have experienced either the high-voltage system restart issue after a 12V under-voltage event or vibrations in your head-up display, you should contact your authorized Audi dealership. Since this is a software update, it is typically performed free of charge under warranty. The dealership will be able to verify if your specific vehicle requires the Update 9308 and perform the necessary software programming for the Hybrid Battery Management Control Module (-J840-) and the Head-Up-Display Control Module (-J898-). This Audi e-tron GT software update will ensure your vehicle operates as intended.
