2021-2024 Audi MIB3 Infotainment System Update Overview

Audi Technical Service Bulletin (TSB) 00 24 01 2076404/1 outlines the planned deployment of customer service software packages for various 2021-2024 Audi vehicles. This TSB serves as an informational guide for technicians regarding future software updates for vehicles equipped with the MIB3 infotainment system, connectivity box, OCU3, and LSR components on both MLB and MQB platforms. The updates aim to address general customer complaints related to the infotainment system's performance and functionality.

Symptoms

Owners may experience various issues that lead to general "Complaints regarding the infotainment system." While this TSB doesn't detail specific fault codes for these complaints, it indicates that the upcoming software updates are intended to improve overall system stability and user experience.

Affected Control Units

The customer service packages will include updates for several key control units within the infotainment and communication systems. These include:

Diagnostic address	Control unit name
0x005F	Control unit 1 for information electronics
0x0075	Emergency call module and communication unit
0x0693	Volume regulator

Customer Service Packages Explained

The software updates will be delivered through two distinct customer service packages, with the specific package applied depending on the vehicle model and its configuration. Both packages aim to provide the latest target software for critical control units.

Customer Service Package 1

This package contains new and currently final target software for the information electronics (0x005F) and volume regulator (0x0693). It also includes provisional software for the emergency call module and communication unit (0x0075).

Customer Service Package 2

This package provides the same target software for the information electronics (0x005F) and volume regulator (0x0693) as Package 1. Additionally, it contains the final target software for the emergency call module and communication unit (0x0075).

These updates are designed for service application only and are not deployed during series production of new vehicles. Ensuring your Audi e-tron MIB3 update is performed at a dealership will provide these enhancements.

Vehicle platform	Customer service package 1	Customer service package 2
