2024 Audi e-tron GT MyAudi App Charging & Climate Fault

Symptoms

Owners of 2024 Audi e-tron GT and RS e-tron GT models may encounter significant inconvenience when attempting to use the myAudi app to control essential vehicle functions. Specifically, the app might fail to set the air conditioner and charging timers, as well as the charging target and location. This issue, described in Technical Service Bulletin (TSB) 2075406/2, directly impacts the ability to remotely manage cabin climate pre-conditioning and optimize charging schedules, which are key features for electric vehicle owners. The inability to utilize these remote functions can disrupt daily routines and reduce the convenience expected from a premium electric vehicle.

When these issues occur, a specific error message appears within the myAudi app, clearly indicating a communication problem. The verbatim message displayed is: "Could not send the desired target charge An error occurred. Please try again. Error: E:BFF.4002 (240419001851)". This message is crucial for identifying the problem, as it includes the specific fault code BFF.4002. Other owner-facing indications include the general inability to perform actions like "setting the air conditioner and charging timers via the myAudi app" and the observation that "charging target and charging location cannot be set via the myAudi app".

Fault Codes / OEM Labels

The primary identifier for this issue is the fault code BFF.4002. This code is prominently displayed within the myAudi app's error message, specifically as E:BFF.4002 (240419001851). It's important to note that this is an application-level error code, not a diagnostic trouble code (DTC) stored in the vehicle's control modules. The specific string 'E:BFF.4002 (240419001851)' helps both owners and technicians pinpoint the exact nature of the communication failure between the myAudi app and Audi's backend systems. The verbatim owner-facing strings associated with this 2024 Audi e-tron GT MyAudi app fault include: "An error occurs when trying to set the air conditioner and charging timers via the myAudi app", "charging target and charging location cannot be set via the myAudi app", "Could not send the desired target charge", and "An error occurred. Please try again." These messages directly inform the user about the failure to execute remote commands for climate and charging.

Diagnosis / Trigger Conditions

This 2024 Audi e-tron GT MyAudi app fault specifically affects 2024 Audi e-tron GT and RS e-tron GT vehicles. The condition is observed in vehicles equipped with software version 0025 in diagnostic address 0019. The problem is consistently reproducible when attempting to set air conditioning or charging parameters via the myAudi app. Workshop findings confirmed that the complaint could be reproduced in the myAudi app, while these same settings could be made directly in the vehicle. This distinction was critical in diagnosing the problem as originating from the app's interaction with the backend service, rather than a malfunction of the vehicle's internal climate control or charging management systems. The underlying cause was identified as a backend system issue rather than a fault within the vehicle's hardware or on-board software, meaning the vehicle itself was functioning correctly.

Resolution

Audi has effectively addressed the 2024 Audi e-tron GT MyAudi app fault through a comprehensive backend software update. The production solution involved implementing updates for software 3039 in diagnostic address 0019 on Audi's server infrastructure. This means the fix was applied to the cloud-based systems that facilitate communication between the myAudi app and the vehicles, specifically targeting the components responsible for handling remote commands for air conditioning and charging functions. The 'Service' section of TSB 2075406/2 explicitly states that 'The backend has already been updated on all vehicles on the backend.' This server-side resolution ensures that the issue is resolved for all affected vehicles without requiring any physical repair or software update to be performed directly on the 2024 Audi e-tron GT or RS e-tron GT vehicles. The problem was entirely resolved on Audi's server side, ensuring a seamless fix for owners without the need for a dealership visit or any vehicle downtime.
