2021-2022 Audi MIB3 Star Button Function Deletes Itself

Symptoms

Owners of 2021-2022 Audi vehicles may notice that the star button on their multi-function steering wheel loses its programmed function after a bus sleep cycle. This means that functions assigned to the star button, such as "Camera view: Front corner", "Camera view: Front tires", or "Traffic sign display", can no longer be activated. When the star button is pressed, instead of performing the assigned action, the selection menu for assigning this button reappears on the MMI display, indicating that the Audi MIB3 star button function has been deleted.

Technical Background

This issue, where the Audi MIB3 star button function deletes itself, has been identified as a software problem within the vehicle's control unit 1 for information electronics, designated as 005F. Audi's workshop findings confirm that the complaint is reproducible, meaning the loss of function can be consistently observed after the vehicle enters a bus sleep state. This indicates a systemic software anomaly rather than an intermittent hardware fault.

Production Solution

Audi has implemented a production solution for this software issue. Vehicles manufactured from calendar week 25/2023 onwards will include the necessary software update to prevent the Audi MIB3 star button function from deleting itself. This means newly produced vehicles will not experience this specific problem.

Important Warnings for Owners

It is critical for owners to understand that no repairs are necessary at this point for the star button issue. The Technical Service Bulletin explicitly states: "Do not replace any components for this condition since this will not resolve the customer's concern." Attempting to replace parts or perform other repairs will not fix the problem and could lead to unnecessary costs. Furthermore, "Unjustified work/replacement parts will be charged back" by Audi, as this TSB is informational only and not applicable to any Audi Warranty for parts replacement.

What Owners Should Do

If you experience the star button on your 2021-2022 Audi losing its programmed function, you should contact your authorized Audi dealer. They are aware of this issue and are instructed to explain that a solution is being worked on. Dealers are also required to create a PSS (Pending Service Solutions) record in the PSS application via AccessAudi (under Related Links >> Service) for affected vehicles. For information regarding the timeline for a permanent software fix for existing vehicles, technicians are referred to TSB 2076404.
