2023 Audi MIB3 Radio Plays When Parked TSB 2079194/1

Audi has issued Technical Service Bulletin (TSB) 2079194/1 to address a condition where the MIB3 infotainment system's radio may turn on automatically when the vehicle is parked. This issue, described as the "Audi MIB3 radio plays when parked," affects various 2023 Audi models, including the A3, A4, A5, A6, A7, A8, Q3, Q5, Q7, Q8, and e-tron. This TSB, released for publishing on September 10, 2025, supersedes previous bulletin PSS 2071923, which also covered the "91 MIB3: radio plays when vehicle is parked" topic. The problem is attributed to a software issue within the MIB3 system's information electronics control unit (Diagnostic address 005F - Information electronics 1).

Symptoms

Owners of affected 2023 Audi vehicles may experience the "Audi MIB3 radio plays when parked" symptom. The primary complaint is that the radio begins playing even when the vehicle is parked and the ignition is off. This behavior can occur intermittently after leaving the vehicle. When this happens, the infotainment screen may sometimes appear "black" or unresponsive. Typically, if the driver's door is opened, the radio will stop playing. The radio usually starts playing approximately one minute after the vehicle has been left. This sporadic nature can make the complaint difficult for technicians to consistently reproduce during diagnosis.

Technical Background

Audi has identified the root cause of this unexpected radio operation as a software issue within the MIB3 infotainment system. Specifically, the problem originates in the Information Electronics 1 control unit, which is identified by diagnostic address 005F. This software anomaly causes the MMI (Multi Media Interface) to switch on or off by itself, leading to the radio playing without user input while the vehicle is parked. The affected software version is indicated as 38**.

Important Warnings and Owner Information

Audi has provided crucial information for owners regarding this condition in TSB 2079194/1:

• Deactivation: If the radio plays while the doors are closed (even if the vehicle is already locked), opening the driver's door briefly can deactivate the audio output. It is important to note that "The system can only be deactivated again by opening the driver's door. Opening other doors or the luggage compartment does not deactivate the audio output."
• Automatic Shut-off: Alternatively, the system will automatically switch itself off after a few minutes, typically less than five minutes.
• Battery Impact: Audi explicitly states, "This cannot damage the battery or drain it completely." Owners should not be concerned about battery discharge due to this intermittent radio activity.

Repair Procedure Summary

The resolution for the "Audi MIB3 radio plays when parked" issue involves a software update for the MMI system. This Technical Service Bulletin (TSB) 2079194/1 serves as a reference document and supersedes PSS 2071923. The actual software update procedure is detailed in a separate bulletin, TSB 2076404, titled "00 Service info: deployment overview for customer service packages MLB and MQB for MIB3/connectivity box." Authorized Audi technicians will follow the instructions in TSB 2076404 to update the MMI software, which is designed to correct the intermittent and spontaneous radio operation. This update targets the Information Electronics 1 control unit (005F) to ensure proper functionality of the MIB3 system.
