2024-2025 Audi MIB3 Date Setting Issue TSB

Audi has identified a common concern for owners of certain 2024-2025 Audi vehicles equipped with the MIB3 infotainment system but without the navigation feature. This issue, detailed in Technical Service Bulletin (TSB) 91 24 77 2075861/1, relates to the vehicle's date and time settings.

Specifically, the TSB addresses situations where the Audi MIB3 date setting is problematic, leading to an incorrect or difficult-to-adjust date display. This can be a minor annoyance for drivers who rely on their vehicle's system for accurate timekeeping.

Symptoms Owners May Experience

Owners of affected 2024-2025 Audi vehicles may observe the following symptoms related to the Audi MIB3 date setting:

• Difficulty Setting Date: The date does not set itself automatically, or it is very complicated to set manually through the MIB3 interface. This often occurs within the "Settings" > "Date & time" menu, where the date field might show an incorrect value like "07/23/2024" when it should be current.
• Incorrect Date Display: The system may display "A date from the past is displayed," indicating that the infotainment system's internal clock is significantly out of sync with the actual date.
• Limited Adjustment: When attempting to correct the date, the system only allows changes one day at a time, making it tedious to correct a date that is far in the past.

These issues are typically reproducible and indicate the underlying software problem, as confirmed by workshop findings.

Technical Background of the Issue

According to TSB 91 24 77 2075861/1, the root cause is a software issue within the vehicle's information electronics J794, specifically identified by address word 005F. This particular control unit manages various infotainment functions, including date and time synchronization.

Vehicles without the navigation feature do not have an active GPS time function. Normally, GPS signals are used to automatically set and maintain accurate time and date. Without this function, the MIB3 system cannot automatically adjust the time, leading to the manual Audi MIB3 date setting difficulties. If navigation is purchased later via
