2023 Audi MIB3 Radio Plays When Parked TSB

Audi has issued Technical Service Bulletin (TSB) 2079194/1 to address a software-related concern affecting various 2023 models equipped with the MIB3 infotainment system. This TSB specifically details instances where the vehicle's radio may spontaneously begin playing even when the car is parked and turned off.

Symptoms

Owners of affected 2023 Audi vehicles may observe the following symptoms:

• The radio plays intermittently when the vehicle is parked and the ignition is off.
• The MMI screen may sometimes appear black when this issue occurs.
• Opening the driver's door typically causes the radio to stop playing.

This behavior is often sporadic and can be difficult for technicians to reproduce consistently. If your Audi e-tron radio plays when parked, it indicates your vehicle may be experiencing this software issue.

Technical Background

Audi has identified the root cause of the radio playing when the vehicle is parked as a software issue within the MIB3 infotainment system. This TSB (2079194/1) replaces a previous Production Solution Service (PSS) 2071923, which also addressed the same concern.

The radio may start playing approximately one minute after the vehicle is left. If the vehicle is locked, briefly opening the driver's door can deactivate the audio output. The system is also designed to automatically switch itself off after a few minutes (typically less than 5 minutes).

Important: Audi explicitly states that this condition will not damage the battery or drain it completely.

Repair Procedure Summary

The resolution for the issue where the Audi e-tron radio plays when parked involves updating the MMI software. Technicians are instructed to follow the guidelines provided in a separate document, TSB 2076404. This accompanying TSB, titled "00 Service info: deployment overview for customer service packages MLB and MQB for MIB3/connectivity box," provides the detailed instructions for the software update process.

This update targets the Information electronics control unit, typically found at diagnostic address 005F, to address the underlying software anomaly.

Owner Action

If you experience your 2023 Audi's radio playing when parked, it is recommended to schedule a service appointment with an authorized Audi dealership. This TSB is for reference only, meaning that while it describes the problem and solution, the actual billing information for the software update procedure is contained within TSB 2076404.

Audi has indicated that repairs performed under this TSB should not be billed to the customer, implying that the software update is covered under warranty or as a service action.
