2023 Audi Radio Plays When Parked TSB 91 24 82

Audi has released Technical Service Bulletin (TSB) 91 24 82, superseding the previous TSB 23-38, to address a common concern among owners of certain 2023 Audi models. This bulletin, updated on March 4, 2024, specifically details instances where the "Audi radio plays when parked" even after the vehicle has been turned off.

The TSB explains that this is a software-related issue, and while a permanent solution is in development, Audi has provided guidance for both technicians and vehicle owners. It's important for owners to understand the nature of this problem and the recommended actions.

Symptoms

Owners of affected 2023 Audi vehicles may notice that the radio continues to play after the ignition is switched off and the vehicle is parked. This can occur regardless of whether the MMI (Multi Media Interface) screen is on or off when the vehicle is parked. The primary symptom is simply that "the radio plays while the vehicle is parked."

Workshop Findings

When technicians investigate this complaint, they typically find that "No relevant DTCs are stored." This means that the vehicle's diagnostic system does not register any fault codes related to the radio continuing to play. Audi notes that the complaint occurs sporadically and can be difficult to reproduce consistently.

Technical Background

Audi has identified the root cause as a software issue within the vehicle's MIB3 system. This software glitch causes the radio to remain active for a period after the vehicle is parked. However, the system is designed to automatically shut off the radio after approximately 5 to 15 minutes. Audi states that this behavior "should not impact the vehicle's 12V battery SoC excessively," meaning it's unlikely to cause significant battery drain.

Important Warnings for Owners

Audi has provided crucial instructions regarding this issue:

• "Do not replace any components for this condition since this will not resolve the customer's concern." This means owners should not authorize or pay for replacement radio units or other components, as it will not fix the underlying software problem.
• "This TSB is informational only and not applicable to any Audi Warranty." While the issue is acknowledged, the current TSB is for informational purposes and does not cover a repair under standard warranty terms, as no repair is yet available.

What to Expect for a Fix

Audi expects a permanent software solution to be available by the end of the 4th quarter of 2024. This timeline is subject to change. Until then, no repairs are necessary, and technicians are instructed not to perform any component replacements.

Temporary Workaround

If the "Audi radio plays when parked" and you wish to turn it off immediately, there is a simple workaround. Briefly opening the driver's door can deactivate the audio output. Alternatively, the system will automatically deactivate the audio after 5-15 minutes.

Owner Action

If you experience your "Audi radio plays when parked," you should inform your Audi dealer about the issue. While no repair is currently available, dealers are instructed to create a Pending Service Solutions (PSS) record in the PSS application. This helps Audi track the prevalence of the issue and ensures that your vehicle is noted for the future software update when it becomes available. You can find information on creating a PSS record through the Pending Service Solutions (PSS) link in AccessAudi (under Related Links >> Service).
