2022-2023 Audi MIB3 Radio Favorites Lost TSB

Owners of certain 2022-2023 Audi vehicles equipped with the MIB3 infotainment system may experience issues where their radio favorites disappear or their radio shortcuts on the lower MMI screen are grayed out. Audi has released Technical Service Bulletin 91 PSS MIB3, reference number 2073135/2, to address this concern. This bulletin supersedes an earlier bulletin, Group 91 number 24-77, dated February 23, 2024.

Symptoms

Owners may observe one or both of the following conditions in their vehicle:

• "Radio favorites are sporadically lost."
• On vehicles with dual MMI screens, "some or all radio shortcuts on the lower screen are grayed out."

These symptoms indicate a problem with the infotainment system's ability to retain user preferences or display them correctly.

Fault Codes / DTCs

According to the workshop findings in TSB 91 PSS MIB3 (2073135/2), there are no relevant Diagnostic Trouble Codes (DTCs) stored in the vehicle's system when these symptoms occur. This suggests the issue is purely software-related and does not trigger a diagnostic fault code.

Technical Background

Audi has identified that a software-related issue is the root cause for the Audi MIB3 radio favorites lost problem and the grayed-out shortcuts. This indicates that the MIB3 infotainment system's programming is not correctly managing or displaying the stored radio favorites and shortcuts.

Important Warnings for Owners

Audi provides crucial guidance for owners and technicians regarding this issue:

• "Explain to the customer that a solution is expected to be available by the end of the 4th quarter of 2024 (subject to change) and that no repairs are necessary at this point. Do not replace any components for this condition since this will not resolve the customer's concern."
• This TSB is informational only and is "not applicable to any Audi Warranty."

This means owners should not attempt to replace any hardware components, as it will not fix the Audi MIB3 radio favorites lost issue. A software update is anticipated to resolve the problem.

Interim Solution and Next Steps

While a permanent software solution is still under development and expected by the end of Q4 2024, Audi is asking technicians to create a Pending Service Solutions (PSS) record. This record helps Audi track the prevalence of the Audi MIB3 radio favorites lost issue.

An older TSB, 2069112 (91 MIB3: favorites/home address/destinations lost, blue screen, various other improvements (CL35' update)), addresses similar issues with navigation favorites and Home/Work addresses. However, TSB 91 PSS MIB3 (2073135/2) specifically applies to radio favorites being lost or grayed out. Owners experiencing this specific radio favorite issue should inform their Audi service center so a PSS record can be created.
