2022 Audi e-tron GT Charging Flap Status TSB 2079475/2

2022 Audi e-tron GT Charging Flap Status Issue

Owners of 2022 Audi e-tron GT and RS e-tron GT models may encounter an incorrect "charging flap open" message displayed in the virtual cockpit, even when the charging flap is securely closed. This condition, detailed in Audi Technical Service Bulletin (TSB) 2079475/2, is a software-related problem affecting the vehicle's virtual cockpit system. The TSB provides specific instructions for dealerships to update the virtual cockpit software, resolving the misleading warning. This ensures the accurate display of the charging flap status and prevents unnecessary concern for drivers.

Symptoms of Incorrect Charging Flap Status

The most noticeable symptom for owners of affected 2022 Audi e-tron GT and RS e-tron GT vehicles is the persistent and incorrect display of a "charging flap open" warning in the Audi virtual cockpit. This occurs even when the charging flap is physically closed and secured. Drivers will typically encounter one of two specific messages: "Vehicle charging connection: please close charging flap" or "Vehicle charging connection: charging not possible. Please close a charging flap." These messages can be confusing and frustrating, as they suggest a problem that doesn't physically exist. The erroneous 2022 Audi e-tron GT charging flap status can lead drivers to believe there's a malfunction with their charging system or that the vehicle isn't secure, potentially causing unnecessary concern or even prompting an unscheduled service visit. This TSB aims to eliminate these misleading notifications.

Technical Background

Audi's Technical Service Bulletin 2079475/2 clarifies that the underlying cause of the incorrect 2022 Audi e-tron GT charging flap status is a software anomaly within the Audi virtual cockpit. Specifically, the diagnostic address 0017, which manages the virtual cockpit's functions, contains software that misinterprets the signal from the closed charging flap. This results in the system registering the flap as open when it is, in fact, closed. It's crucial to understand that this is a software logic error, not a mechanical failure of the charging flap or its associated hardware, such as the actuator. Audi notes that this software issue occurs even in vehicles equipped with an optimized charging flap actuator. This distinguishes it from a previous issue addressed by TSB 2064953, which dealt with hardware-related incorrect charging port door status displays. Therefore, if the hardware has already been addressed, this software update is the next step to resolve the persistent warning.

Important Warnings for the Repair

Audi has issued a critical warning regarding the software update procedure to prevent potential damage to the vehicle's high-voltage components.

• "To prevent the high-voltage battery from charging during the software update, the high-voltage battery charging cable must be unplugged BEFORE the SVM code is entered. Please note that charging the high-voltage battery during a software update can cause damage to the high-voltage components."

This instruction emphasizes the importance of ensuring the high-voltage charging cable is disconnected before initiating the software update. Failure to follow this step could lead to severe damage.

Repair Procedure Summary

The resolution for the incorrect 2022 Audi e-tron GT charging flap status involves a targeted software update for the Audi virtual cockpit (diagnostic address 0017). The specific software version to be installed depends on the vehicle's current virtual cockpit software.

For Vehicles with Virtual Cockpit Software Version 0111

If the vehicle currently has virtual cockpit software version 0111, the update will bring it to version 0115. This particular update is initiated using SVM code 17A040.

For Vehicles with Virtual Cockpit Software Versions 0084, 0085, 0086, 0087, 0090, or 0091

For vehicles with any of these earlier virtual cockpit software versions, the update will install version 0093. This specific update requires the use of SVM code 17A058.

General Software Update Steps for Technicians

1. Pre-Update Safety Check: Before any software update begins, it is imperative to ensure the high-voltage charging cable is completely unplugged from the vehicle. This critical step prevents potential damage to the high-voltage battery system during the update process.
2. Software Acquisition: Dealership technicians utilize the Flash Media Creator (FMC), identified by part number 4KE 906 961 C, to download the correct software version. This software is then transferred onto a USB stick that meets USB 2.0 specifications.
3. Initiating the Update: The update process is started using the workshop diagnostic tester. Technicians select the "flash" function, which prepares the system for a software re-write, and then input the appropriate SVM code (either 17A040 or 17A058) for the specific software variant.
4. Media Insertion: The diagnostic system will prompt the technician to "please insert update medium with the following part number...". At this point, the prepared USB stick containing the new software is inserted into a suitable USB port within the vehicle, ensuring proper data transmission.
5. Vehicle Key Placement: During the update, a message might appear, such as "...Hold the vehicle key to the transponder...". If this occurs, the vehicle key must be placed in full surface contact against the designated marking in the center console. Maintaining this position is crucial until the Audi virtual cockpit confirms that the update process has successfully started and is proceeding. This ensures continuous communication and prevents interruptions.

This detailed procedure ensures that the virtual cockpit software is correctly updated, thereby resolving the misleading 2022 Audi e-tron GT charging flap status warnings and restoring accurate information to the driver.

Required Tools or Parts

To perform the software update, technicians will need:

• A USB stick that complies with the USB 2.0 specification.
• The FMC (Flash Media Creator) part number 4KE 906 961 C, which is used to download the software.
• Alternatively, a USB stick with part number 4KE 906 961 A or 4KE 906 961 C may be ordered in advance.

Owner Action

If you own a 2022 Audi e-tron GT or RS e-tron GT and are experiencing the "charging flap open" warning message despite the flap being closed, you should contact your authorized Audi dealership. Inform them about the persistent 2022 Audi e-tron GT charging flap status issue and mention Technical Service Bulletin (TSB) 2079475/2. The dealership will be able to diagnose the specific software version of your virtual cockpit and perform the necessary software update. Since this is a software-related fix, it is typically covered under warranty if your vehicle is still within the warranty period. It is important to have this addressed to ensure all vehicle warnings are accurate and reliable.
