2021-2026 Audi iPhone Bluetooth Call Audio Output TSB

Symptoms

Owners of 2021-2026 Audi vehicles may experience issues where call audio from an Apple iPhone is output through the phone's speaker instead of the vehicle's sound system, even when an active Bluetooth connection is established. This problem can occur sporadically during both incoming and outgoing telephone calls. The vehicle's infotainment system may also report a Bluetooth connection communication malfunction or indicate that the receiver cannot be switched on or activated.

Diagnosis / Trigger Conditions

The issue, often described as an Audi iPhone Bluetooth audio problem, typically arises when a phone call is initiated or answered directly from the iPhone itself, rather than through the vehicle's Multi Media Interface (MMI) system. While it may be possible to reproduce this complaint in a workshop setting, its sporadic nature means it might not always be immediately apparent.

Repair Procedure Summary

No vehicle repairs are necessary to address this Audi iPhone Bluetooth audio concern. The solution involves a simple adjustment within the iPhone's accessibility settings. The audio output via Bluetooth will then be preferred when a suitable Bluetooth connection (such as a headset or vehicle system) is detected.
