2020-2025 Audi MIB3 Calendar Function Not Available TSB

Symptoms of Unavailable Calendar Function

Owners of various 2020-2025 Audi models, including the A4, A4 allroad, S4, and other Audi vehicles equipped with the MIB3 infotainment system, may notice that the integrated calendar function is no longer operational. The primary symptom reported by customers is that the "calendar function is not working or is no longer available". This means users cannot access or utilize the calendar feature within their vehicle's infotainment system. For example, if you own an Audi e-tron, you might find your Audi e-tron MIB3 calendar function is not working as expected.

Technical Background and Cause

According to Audi Technical Service Bulletin 91 24 39 2074855/1, the "Calendar" service has been intentionally deactivated. This deactivation is due to specific technical reasons and applies universally to all vehicles equipped with the MIB3 system. Therefore, if you observe that your Audi e-tron MIB3 calendar function is not working, it is a known and intended condition, not a fault with your specific vehicle or its MIB3 unit. This bulletin clarifies that there is no production solution or repair applicable for this status.

Important Warnings for Owners

Audi has issued clear instructions regarding this situation, emphasizing that this is not a fault requiring repair. Owners should be aware of the following critical points:

• Do not perform any repairs. Audi explicitly states, "Do not perform any repairs. Any repairs for this concern may be denied." Attempting to fix this non-existent "fault" could lead to warranty claims being rejected for any work performed related to this issue.
• This condition is normal. Dealerships are instructed to "Instruct the customer that this condition is normal." This means the unavailability of the calendar function is an expected state due to the service deactivation, and not indicative of a malfunction.
• No production solution. The bulletin specifies that there is "Not applicable" for a production solution, reinforcing that this is a service deactivation, not a defect to be corrected by manufacturing.

Future Outlook and What Owners Should Know

Audi is currently evaluating the possibility of reactivating the calendar function within the MIB3 system. The results of this evaluation are expected to be available in Calendar Week 37 of 2024. Until then, the Audi e-tron MIB3 calendar function, along with the calendar function in other affected models, will remain unavailable.

This Technical Service Bulletin (TSB 2074855) is purely informational. It serves to inform technicians and customers about the status of the MIB3 calendar function. As such, it is "not applicable to any Audi Warranty" for repairs, because no repair is authorized or necessary. Owners should not expect a repair or a specific recall for this issue, but rather await potential future updates regarding the service's reactivation.
