2023 Audi MMI "Loading system. Please wait..." TSB

Symptoms of the Audi MMI Loading System Issue

If you own a 2023 Audi, you might encounter a specific issue with your Multi Media Interface (MMI) system. The primary symptom is the message "Loading system. Please wait..." appearing prominently on the MMI display after the vehicle has been driven for an extended period.

When this message is active, the MMI system's display becomes unresponsive and cannot be operated directly via touch or physical controls. Despite the display being frozen, the MMI system continues to run in the background, and audio output remains functional. Owners can still operate certain MMI functions using the multifunction steering wheel controls. This "Audi MMI loading system" message typically persists until the vehicle is stationary and parked for an extended period, after which the MMI system usually functions normally during the next use of the vehicle.

Technical Background

Audi has identified the root cause of the persistent "Loading system. Please wait..." message as a software issue. This anomaly is located within the information electronics control unit, specifically designated as -J794- (address word 005F). This software glitch prevents the MMI display from updating correctly, leading to the continuous display of the loading message.

Important Warnings for Owners

Audi Technical Service Bulletin 91 24 57 2075325/1 includes critical advisories for both technicians and vehicle owners regarding this issue:

• Specific Condition: "If the message "Loading the system. Please wait..." only appears for a short time after starting the system, this PSS does not apply." This means the bulletin is only relevant if the message appears after extended driving and persists, not if it's a brief startup message.
• No Component Replacement: "No repairs are necessary at this point. Do not replace any components for this condition since this will not resolve the customer's concern." Owners should be aware that replacing parts will not fix this software-related problem.
• Warranty Invoicing: "Replacing parts or attempting repairs will not fix the problem. Unjustified labor / replacement parts will be charged back. Invoicing under warranty is not permitted." This reinforces that dealers are not authorized to perform physical repairs or charge for them under warranty for this specific issue.

Temporary Workaround for the Audi MMI Loading System

While a permanent software solution is being developed, Audi provides a temporary workaround to regain full MMI functionality when the "Loading system. Please wait..." message appears:

1. Locate the MMI on/off button: This button is typically integrated into the MMI control panel in your vehicle.
2. Press and hold: Press and hold the on/off button for at least 10 seconds.
3. Monitor the screen: The MMI screen will go dark temporarily as the system initiates a restart process.
4. System restart: The MMI system will then restart itself.
5. Resume operation: Once the system has restarted, it can be operated normally again via the display.

It is important to note that this is a temporary solution, and the
