2020-2025 Audi MIB3 Calendar Function Not Available TSB

Symptoms

Owners of 2020-2025 Audi vehicles equipped with MIB3 and Audi Connect may observe that the Audi MIB3 calendar function is not operating as expected. The primary symptom reported by customers is that "The calendar function is not working or is no longer available." This issue manifests within the infotainment system, specifically when attempting to access the calendar information display via the mobile telephone screen image (WLAN connection) under the path of information, navigation, communication, entertainment -> cell phone functions, customer portal, applications.

Customers might encounter several specific complaint types related to the unavailability of the Audi MIB3 calendar function:

• Functionality cannot be selected: The option to access the calendar feature may be grayed out or unresponsive, preventing any interaction with it.
• Control modules, services -> data missing: While the calendar function might be accessible, it fails to display any data, indicating that the underlying service or its content is absent.
• Functionality -> no function: The calendar feature appears to be present but is completely inert, offering no response or interaction when selected.
• Functionality -> operation sequence incorrect: Attempts to use the calendar function result in an error or an unexpected operational flow, preventing proper use.

These various manifestations all point to the same underlying condition: the Audi MIB3 calendar function is unavailable due to an intentional deactivation.

Important Warnings for Owners and Technicians

Audi Technical Service Bulletin 2074855/3 includes critical advisories that owners and service technicians must heed to avoid unnecessary work, potential charges, and misdiagnosis. These warnings clarify that the reported issue is not a defect requiring repair but rather a normal operating condition:

• Do not perform any repairs: The TSB explicitly states, "Do not perform any repairs. Any repairs for this concern may be denied." This instruction is crucial because attempting to fix a feature that has been intentionally deactivated will not resolve the issue and could lead to warranty claims being rejected by Audi. Technicians should understand that there is no diagnostic or repair procedure for this condition.
• Instruct the customer that this condition is normal: Service personnel are directed to inform vehicle owners that the unavailability of the calendar function is an expected and normal state for the vehicle. This helps manage customer expectations and prevents unnecessary service visits.
• Do not replace components: A specific caution within the TSB warns, "There is no reason to replace components. If components are replaced without good reason under warranty, this will be charged back." This prevents dealerships from replacing costly parts, such as the MIB3 control unit, which would not resolve the issue and would result in the dealership incurring the cost of the part and labor without reimbursement.

These warnings underscore that the unavailability of the Audi MIB3 calendar function is an intended state, not a fault requiring intervention.

Technical Background

Audi has confirmed that the "Calendar" service, which is an integral part of the MIB3 infotainment system and Audi Connect features, is no longer available. This is not a malfunction, a software bug, or a fault that can be corrected through standard diagnostic or repair procedures. Instead, the service has been intentionally "deactivated for technical reasons." This deactivation is a systemic change that applies universally to all affected vehicles equipped with MIB3 and Audi Connect. The TSB explicitly states, "Production Solution: Not applicable," reinforcing that there is no manufacturing defect or a future production change planned to re-enable this feature.

This information is provided to clarify the situation for both technicians and vehicle owners, ensuring that resources are not wasted on attempting to diagnose or repair a feature that has been deliberately disabled by the manufacturer. The TSB, identified as Transaction No. 2074855/3, serves as the official communication regarding this change, originating from the United States market area (Volkswagen of America, Inc. (6444)).

Owner Action

If you own a 2020-2025 Audi vehicle with MIB3 and Audi Connect and notice that the Audi MIB3 calendar function is not working or is no longer available, there is no action required on your part. You do not need to take your vehicle to a dealership for this specific concern, as no repair is possible or necessary. The TSB explicitly advises technicians to "Instruct the customer that this condition is normal," indicating that this is an intended state of the system.

This TSB is informational only and does not fall under any Audi Warranty for repair. Therefore, any attempts to have this issue addressed as a warranty claim will likely be denied, and any associated costs for diagnosis or attempted repair would not be covered. Owners should understand that the unavailability of the calendar function is a known and accepted condition by the manufacturer, and it is not considered a defect.
