2023 Audi MIB3 Incorrect Time Display TSB

Symptoms

Owners of affected 2023 Audi vehicles may notice the following symptoms related to the 2023 Audi MIB3 incorrect time display:

• The time shown on the instrument cluster and/or the MMI display is sometimes incorrect.
• After a few minutes of driving, the time display often synchronizes itself again, returning to the correct time.

It's important to note that during workshop diagnosis for this issue, no relevant Diagnostic Trouble Codes (DTCs) are typically stored in the vehicle's system.

Technical Background

Audi has identified that a software issue is the root cause of the 2023 Audi MIB3 incorrect time display. This software glitch can lead to the time becoming desynchronized between the MMI (Multi Media Interface) and the instrument cluster. This desynchronization is temporary, as the system usually corrects itself after a short period of driving.

This issue is not related to a hardware fault, and there is no production solution currently applicable to address this problem in newly manufactured vehicles.

Important Warnings

Audi has provided specific instructions to dealerships regarding this condition:

• Do not replace any components for this condition since this will not resolve the customer's concern. This is a critical warning, as replacing parts like the instrument cluster or MMI unit will not fix the underlying software problem and would result in unnecessary costs or warranty claims.

Service Action

For owners experiencing the 2023 Audi MIB3 incorrect time display, Audi dealerships are instructed to take the following actions:

1. Customer Communication: Explain to the customer that a permanent solution for this software issue is currently under development and is expected to be available by the end of the 4th quarter of 2024. This timeline is subject to change.
2. No Immediate Repairs: Reiterate that no repairs are necessary at this point, and no components should be replaced, as this will not resolve the issue.
3. Documentation: Dealerships are required to create a PSS (Pending Service Solutions) record in the AccessAudi application. This record helps Audi track the prevalence of the issue and ensures that affected vehicles are noted for future resolution.

Warranty Information

Technical Service Bulletin 91 23 35 2071921/1 is classified as informational only. This means that the TSB itself is not applicable for any Audi Warranty claims. Any future repair or software update related to this issue would be handled under separate warranty guidelines or service campaigns once a solution is released.

What Owners Should Do

If your 2023 Audi is exhibiting the "incorrect time shown on the instrument cluster or MMI display" symptom, you should contact your authorized Audi dealership. While there is no immediate fix, informing your dealer allows them to document the issue by creating a PSS record. This ensures your vehicle is noted for the upcoming software solution expected in late 2024. Do not attempt to replace any components yourself, as this TSB explicitly states it will not resolve the problem.
