2023 Audi MIB3 'Loading system. Please wait...' TSB

Owners of various 2023 Audi models equipped with the MIB3 infotainment system may encounter a persistent message stating "Loading system. Please wait..." on their MMI display. This issue typically arises after the vehicle has been driven for an extended period. Audi has released Technical Service Bulletin (TSB) 91 24 99 2075325/2 to address this condition, providing information and a temporary workaround while a permanent solution is developed.

This TSB, identified as 91 PSS MIB3, is a revision (Revision 2) of a previous bulletin (Group 91 number 24-57 dated September 18, 2024). It supersedes the earlier version due to updated service information and release dates.

Symptoms

If you own a 2023 Audi model with the MIB3 system and experience the "Loading system. Please wait..." message, you will notice that the MMI display becomes inoperable. While the display is frozen, the MMI system continues to function in the background, including audio output. You can still control some functions using the multifunction steering wheel controls.

The message remains active on the display until the vehicle is parked and stationary for an extended period. Once the vehicle has been off for a while, the MMI system typically functions normally the next time it is used. This specific issue, affecting the Audi e-tron MIB3 loading system among others, is distinct from a brief loading message that might appear when first starting the vehicle.

Diagnosis / Trigger Conditions

Audi's workshop findings indicate that this customer complaint cannot always be easily reproduced. The "Loading system. Please wait..." behavior only occurs after the vehicle has been driven for a significant duration. Technicians have noted that the message persists throughout the vehicle's bus cycle until it is parked for an extended period, after which the MMI functions normally on subsequent use.

Technical Background

The root cause of this MMI display issue is a software problem within the control unit one for information electronics, identified as -J794- (address word 005F). Audi is actively working on a resolution for this software anomaly. For 2024 model year vehicles, software versions greater than 4000 are expected to incorporate a fix.

Important Warnings

Audi explicitly states critical information for both owners and service technicians regarding this issue:

• "If the message 'Loading the system. Please wait...' only appears for a short time after starting the system, this PSS does not apply." This TSB specifically addresses the persistent message after extended driving, not brief startup loading screens.
• "Do not replace any components for this condition since this will not resolve the customer's concern." Attempting to replace parts will not fix the underlying software issue and is not recommended.
• "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 is a crucial warning for owners, as any unauthorized repairs or part replacements will not be covered under warranty and will result in charges.

Workaround

While Audi works on a permanent software update, a temporary workaround is available to restore MMI functionality:

1. Restart the MMI: Press and hold the on/off button for at least 10 seconds.
2. The MMI screen will go dark temporarily, and the system will restart.
3. After the restart, the MMI system should operate normally again.

It is important to note that this is a temporary solution, and the "Loading system. Please wait..." complaint can reoccur after subsequent extended driving periods. This workaround applies to the Audi e-tron MIB3 loading system and other affected models.

What Owners Should Know

Audi advises customers that a definitive solution for this MIB3 software issue is currently being developed. At this time, no repairs are necessary or available. Dealerships are instructed to explain this situation to customers and to create a PSS (Pending Service Solution) record in their system. This record helps Audi track the prevalence of the issue and ensures that affected vehicles are noted for future updates.

This TSB is informational and does not apply to any Audi Warranty claims for repairs, as no repair is currently authorized. Owners should not attempt to have components replaced, as this will not resolve the problem and will not be covered under warranty.
