2020-2026 Audi MIB3 Calendar Function Not Available TSB

Audi has released Technical Service Bulletin (TSB) 2074855/1 to address concerns regarding the Audi MIB3 calendar function in various models from 2020 to 2026. This bulletin clarifies that the unavailability of the calendar feature is not a defect but a result of a deliberate deactivation of the service. This informational TSB provides crucial guidance for both technicians and owners, emphasizing that no repair is necessary.

Understanding the Issue: Audi MIB3 Calendar Function

The core of the issue, as detailed in TSB 2074855/1, is that "The 'Calendar' service is no longer available due to the service having been deactivated for technical reasons." This deactivation applies to all Audi vehicles equipped with the MIB3 infotainment system, specifically impacting models like the A4, A4 allroad, and S4 from 2020-2025, and other Audi vehicles from 2021-2025. This means the absence of the Audi MIB3 calendar function is an intended state, not a malfunction requiring intervention.

Customer Reported Symptoms

Owners encountering this issue will typically observe that "The calendar function is not working or is no longer available" within their vehicle's infotainment system. This might manifest as the calendar icon being grayed out, unresponsive, or simply missing from the available applications. It's important to understand that this symptom does not indicate a fault with the infotainment unit itself or any other vehicle component.

No Repair Action Required

A key directive from Audi in this bulletin is: "Do not perform any repairs. Any repairs for this concern may be denied." This instruction is critical for both dealerships and owners. It explicitly states that attempting to diagnose or repair the unavailable calendar function is not recommended, as it will not resolve the situation. Furthermore, any costs incurred for such unnecessary repairs may not be covered under Audi's warranty.

What Owners Should Know

Audi advises that customers be informed that "this condition is normal." This means the lack of the calendar function is not a sign of a problem with their vehicle. Owners should not be concerned about the safety or functionality of their vehicle due to this deactivated service. The TSB aims to manage customer expectations and prevent unnecessary service appointments for an issue that is not a defect.

Future Evaluation and Potential Reactivation

While the calendar service is currently deactivated, Audi is actively evaluating the possibility of reactivating this feature. The bulletin states, "The possibility of reactivating this feature is currently being evaluated. The results of that evaluation are expected to be available in CW 37 / 2024." This indicates that there might be a future software update or service action to restore the calendar functionality, but no immediate solution is available. Owners are advised to monitor official Audi communications for any updates after this timeframe.

Official Bulletin Details

Technical Service Bulletin 2074855/1, dated August 27, 2024, is categorized as informational only. This classification means it serves to provide information and guidance rather than outlining a specific repair procedure or authorizing warranty claims. As such, it is "not applicable to any Audi Warranty" for the calendar function's unavailability, reinforcing that no repair is necessary or covered.
