2025 Audi A5/S5 Android Auto Nav Volume Reduction TSB

Owners of certain 2025 Audi A5, S5, Q6 e-tron, and SQ6 e-tron models may experience an issue where the 2025 Audi A5 Android Auto volume is lowered or interrupted during navigation prompts. This occurs even if the volume reduction setting for navigation prompts has been disabled within the vehicle's Multi Media Interface (MMI) system. This behavior is detailed in Audi Technical Service Bulletin (TSB) 91 25 02 2076587/1, issued on January 14, 2025.

Symptoms

Customers report specific scenarios where the 2025 Audi A5 Android Auto volume is affected:

• When media is played back via Android Auto, the audio volume is noticeably lowered or completely interrupted during navigation prompts. This happens despite the MMI settings being configured to prevent such volume reduction.
• In contrast, when media is played directly through the MMI's entertainment features (for example, via Bluetooth audio or USB connection), the volume reduction during navigation prompts operates as expected, following the MMI settings.

Diagnosis and Technical Background

Dealership technicians have confirmed that the customer complaint regarding the 2025 Audi A5 Android Auto volume can be consistently reproduced. The technical background clarifies that the audio volume reduction within Android Auto is managed by the paired Android device itself or the specific media playback application being used on that device. Crucially, the audio volume reduction setting within the Audi MMI system does not influence this particular behavior.

What Owners Can Do

Since the behavior originates from the Android device or the specific media playback application, owners should investigate settings within their phone's Android Auto app or the individual navigation/media playback apps. Some of these applications may feature an individual setting regarding muting or interrupting media playback during navigation prompts. If such a setting is not provided within the app, the customer may need to contact the specific app support via the provided support link within the app itself or through the Google Play Store.

Important Warranty Information

Audi has explicitly stated that "Billing under warranty is not permitted" for any service related to this specific issue. This means that any diagnostic or service work performed by an authorized Audi dealership concerning the Android Auto volume behavior described in TSB 91 25 02 2076587/1 will not be covered under your vehicle's warranty. Owners will likely be responsible for any associated costs, as the issue is determined to be external to the vehicle's MMI system.
