2022-2024 Audi e-tron GT Brake System Software Update

Audi has released a dealer communication, identified as UPDATE 49A4, concerning certain 2022-2024 Audi e-tron GT and RS e-tron GT vehicles. This update addresses specific characteristics of the brake system that owners might notice during operation. The primary goal of this service action is to improve the overall braking experience and address the Audi e-tron GT brake noise and pedal feel.

Symptoms and Conditions

Owners of affected 2022-2024 Audi e-tron GT and RS e-tron GT models may experience a louder-than-usual operating noise emanating from the hydraulic unit of the brake system. This Audi e-tron GT brake noise can be particularly noticeable. Additionally, some drivers might observe that the brake pedal travel is higher than expected, especially when driving at very low speeds. These conditions are the focus of the UPDATE 49A4 service action.

Repair Procedure Summary

To resolve these concerns, Audi dealerships are instructed to perform a two-part repair. The first step involves updating the brake electronics software. This software update is designed to optimize the hydraulic unit's operation and address the root cause of the increased noise. Following the software update, technicians will bleed the brake system. This process ensures that any air or old fluid is removed, contributing to a more consistent brake pedal feel and reducing the likelihood of high brake pedal travel.

Dealers are advised to consult the ELSA and Elsa2Go Service References tool for comprehensive repair and claiming instructions. This ensures that the repair is carried out according to Audi's precise specifications. The repair became available starting March 21, 2024.

Important Warnings for Owners

Audi has clarified that this UPDATE 49A4 differs from a recall or a standard service action. Consequently, consumers will not be receiving letters about this action. Owners of 2022-2024 Audi e-tron GT or RS e-tron GT vehicles who experience the described symptoms, such as the Audi e-tron GT brake noise or high brake pedal travel, should proactively contact their authorized Audi dealership to inquire about this update.

Furthermore, Audi has issued strict instructions to dealerships regarding vehicles in their inventory. Affected vehicles currently held by dealers cannot be delivered to consumers until this Update is completed. This measure ensures that all new and certified pre-owned vehicles are brought up to the latest specifications before reaching customers. Dealerships are also required to complete this update on any affected vehicle that comes into their workshop for maintenance or other service visits, provided the Update code is open in ELSA on the day of repair.

What Owners Should Do

If you own a 2022-2024 Audi e-tron GT or RS e-tron GT and have noticed a louder-than-usual hydraulic unit noise or increased brake pedal travel at low speeds, it is recommended to contact your local Audi dealership. Since no owner notification letters will be sent for this UPDATE 49A4, proactive communication with your dealer is essential to ensure your vehicle receives the necessary software update and brake system bleed. The dealership can check your vehicle's eligibility using your VIN and schedule the service accordingly. This update is crucial for maintaining the expected quality and performance of your Audi's braking system.
