2023 Audi MIB3 Infotainment Shortcuts Greyed Out TSB

Owners of various 2023 Audi models, including the A6, A7, A8, Q7, Q8, and e-tron, may encounter an issue where the MIB3 infotainment system's shortcuts become intermittently greyed out and unresponsive. This problem specifically affects the functionality of shortcut keys used for controlling infotainment features, such as radio station selection. This Technical Service Bulletin (TSB) 2079212/1 provides guidance to address this software-related concern.

Symptoms

Customers report that the "Shortcuts to radio stations turn grey after a while and they no longer work." This issue is visually represented on the infotainment display, where the radio station shortcuts at the bottom of the screen appear greyed out and cannot be selected. While deleting and recreating these shortcuts temporarily restores functionality, the problem reoccurs.

Other shortcuts, such as those for home addresses, are typically unaffected by this specific issue. The complaint is primarily related to the functionality of the infotainment system's shortcut keys for radio operation and station selection.

Affected Control Units and Software

The root cause of the greyed-out shortcuts is identified as a software issue within the vehicle's infotainment system. The primary control unit implicated is the Information electronics 1 module, which has a diagnostic address of 005F. Vehicles with Software version 38* are specifically noted in relation to this issue.

Technical Background

Audi has determined that the intermittent greying out of MIB3 infotainment shortcuts is due to an internal software anomaly. This software issue prevents the shortcuts from functioning correctly after a period of use, leading to a loss of functionality for specific infotainment controls.

Repair Procedure Summary

To resolve the issue of the 2023 Audi e-tron MIB3 shortcuts greyed out, technicians are instructed to update the MMI software. This update is the core remedy for the software-related problem. The detailed instructions for performing this MMI software update are provided in a separate document, TSB 2076404 00, titled "Service info: deployment overview for customer service packages MLB and MQB for MIB3/connectivity box."
