Why is there no sound when playing music via Bluetooth in an Audi?

Audi Bluetooth connection has no sound because the audio source on the car's system is not set to Bluetooth. Simply select the Bluetooth player to resolve the issue. Here is some information about Audi: 1. Introduction: Audi is a luxury car brand under Audi AG, a subsidiary of the Volkswagen Group. Representing high technical standards, quality, innovation, and classic car models, Audi is one of the leading automotive brands. 2. Main Models: Audi is a renowned car developer and manufacturer, symbolized by four interlocking rings. Its main models include the A1, A3, A4, A5, A6, A7, Q8, TT, R8, as well as the S and RS performance series.

Last time I drove my friend's Audi Q5L and encountered the same situation. After pondering for a while, I realized it's actually quite simple. Just because your phone's Bluetooth is connected doesn't mean the audio channel has switched over. You need to tap the 'Media' option on the central control screen and manually switch to the Bluetooth audio source. For older models like my friend's A4, note that phone and audio permissions are separate - you'll need to check 'Media Audio' in your phone's Bluetooth settings. Also, if the Audi's driving mode is set to Efficiency, the sound effects might be suppressed; switching back to Comfort mode should fix it. If none of these work, try rebooting the infotainment system by long-pressing the volume knob on the center console - this solves 80% of such issues.

From an auto repair perspective, troubleshooting Audi Bluetooth audio issues follows a systematic process. First, check the mobile device: ensure media volume isn't muted and airplane mode isn't accidentally activated. Second, inspect vehicle settings: access the connection management in MMI system, delete old pairings and reconnect. Third, verify hardware pathways: having a CarPlay cable connected simultaneously may occupy the Bluetooth audio channel - unplugging it should restore normal function. Fourth, test audio channel separation: make a phone call to verify if earpiece audio works; if it does, this indicates incorrect media stream configuration. The ultimate solution is factory reset: press and hold the volume knob + top-right button for 10 seconds, which saves you 2000 yuan in dealership diagnostic fees.

After driving the A6 for three years, I've been caught out by this issue three times, and now I can handle it with my eyes closed. Focus on checking four key areas: whether the volume scroll wheel on the right side of the steering wheel has been accidentally muted; if the mute button near the electronic gear shift on the center console is lit red; whether the media access for Audi Bluetooth is disabled in the phone's app permissions; and the most annoying one—Audi's intelligent volume balance feature, which automatically suppresses music volume during navigation announcements—simply turn off 'Dynamic Volume' in the sound settings. Oh, and if you're using a Huawei phone, remember to disable the LDAC option in the Bluetooth codec settings, as Audi only supports basic SBC transmission.
