2022-2026 Audi iPhone Bluetooth Call Audio Output TSB

Symptoms of Audi iPhone Bluetooth Call Audio Issues

Owners of 2022-2026 Audi vehicles equipped with Bluetooth may experience problems with call audio output when using an Apple iPhone. Despite the iPhone being actively connected to the vehicle's Bluetooth system, call audio may continue to play through the iPhone's internal speaker rather than the car's sound system. This can occur sporadically during both incoming and outgoing telephone calls.

The core complaint is that the Audi iPhone Bluetooth call audio does not route correctly, requiring manual switching during a conversation. This can manifest as the inability to switch the receiver on or off, or a general communication malfunction related to the Bluetooth connection and the cell phone hands-free profile (HFP).

Understanding the Issue

According to Audi TSB 2079283/1, this condition typically arises when a call is started or accepted by operating the iPhone directly, rather than through the Audi's Multi Media Interface (MMI) system. When the phone is operated directly, the audio may default to the iPhone's speakers instead of the vehicle's. This is why the Audi iPhone Bluetooth call audio might not function as expected.

Workshop findings suggest that reproducing the complaint can be challenging, as it often depends on the user's behavior. The issue is most consistently observed when the phone is used directly to manage calls, rather than relying on the MMI for call initiation or acceptance. This indicates that the problem is not with the Audi's Bluetooth hardware, but rather with the iPhone's default audio routing behavior in certain scenarios.

Important Warnings for Owners

Audi explicitly states that this concern stems from a third-party system (the Apple iPhone) and is therefore not covered by any Audi Warranty. Owners should be aware of the following:

• Do not replace parts: Replacing any vehicle components or attempting other repairs will not resolve this specific issue. The TSB notes that "Replacing parts or attempting repairs will not fix the problem."
• No warranty coverage: Any unjustified work or replacement parts will be charged back to the owner, and "Invoicing under warranty is not permitted." for this problem.

This means that owners should not seek a dealer repair for this specific Audi iPhone Bluetooth call audio problem, as it will likely not be covered and could result in charges.

Repair Procedure Summary

No vehicle repairs are necessary to address the Audi iPhone Bluetooth call audio problem. The solution involves a simple adjustment to the iPhone's accessibility settings. This TSB outlines the following steps to ensure audio output is correctly routed to the Bluetooth connection:

1. On your Apple iPhone, navigate to the "Settings" application.
2. Within Settings, select "Accessibility."
3. Tap on "Touch."
4. Locate and select "Call Audio Routing."
5. Change the setting from "Automatic" to "Bluetooth Headset."

By making this change, the iPhone will prioritize Bluetooth audio output when a suitable Bluetooth connection, such as your Audi's hands-free system, is detected.

Owner Action

If you are experiencing issues with your Audi iPhone Bluetooth call audio not routing through your vehicle's speakers, you can resolve this yourself by following the iPhone setting adjustment described above. This is a user-configurable setting on the iPhone and does not require a visit to an Audi dealership. Remember that Audi TSB 2079283/1 clarifies that this is not a vehicle defect and is not covered under warranty.
