This informational bulletin, released on September 26, 2025, details the planned deployment of software updates following UNECE regulations, aiming to resolve various infotainment and connectivity complaints reported by owners.

This TSB serves as a reference for technicians, outlining which control units may be updated as part of these future service packages. It is important to note that this document is for informational purposes only and does not detail a specific repair procedure for current issues.

Important Warning for Owners

This TSB 2079416/1 is for reference only. Do not bill repairs under this TSB. Billing information for any software update instructions will be found in relevant, specific TSBs once the solutions are deployed. This means that while this bulletin acknowledges potential issues, it does not authorize immediate, billable repairs based on its content alone.

Overview of MMI Service Packages

Audi is planning to deploy customer service packages for vehicles utilizing the MIB3 system, which includes the ConBox, OCU3, AED2, and gateway components. These packages are designed to address a range of customer complaints related to infotainment and connectivity functionality. The updates are part of a broader UNECE deployment strategy, ensuring compliance and enhancing user experience across various vehicle models.

Affected Control Units

As part of the planned customer service packages, several key control units within the vehicle's infotainment and communication architecture may receive software updates. These include:

• 0x005F: Control unit 1 for information electronics
• 0x0075: Emergency call module and communication unit
• 0x0019: Data bus diagnostic interface (gateway)
• 0X078E: Android control unit 2

These updates are software-based and are intended for service work, meaning they are not deployed in series production vehicles but will be applied during dealership visits as part of the service packages.
