2022-2026 Audi Poor Bluetooth Call Quality TSB

If you own a 2022-2026 Audi and experience Audi poor voice quality during Bluetooth calls with your iPhone, you're not alone. Audi has issued Technical Service Bulletin (TSB) 2078728/1 to address this specific concern. This bulletin clarifies that the issue stems from software incompatibilities with certain iOS versions and provides a simple solution for owners.

Symptoms

Owners of affected 2022-2026 Audi vehicles may notice Audi poor voice quality when making or receiving calls via Bluetooth. The person on the other end of the line often reports difficulty understanding the Audi driver, especially at higher speeds or when there is significant background noise. They might describe the voice as muffled, distorted, or simply hard to comprehend.

It's important to note that this issue specifically pertains to direct Bluetooth telephone operation. The voice quality when using Apple CarPlay for calls is generally unaffected.

Diagnosis / Trigger Conditions

Audi's workshop findings confirm that the complaint of poor voice quality can be reproduced. The technical background indicates that the problem is linked to software issues within Apple iPhone's iOS versions 18.0.x through 18.4.x. These software issues can interfere with the Bluetooth connection's audio fidelity, leading to the reported poor voice quality.

Owner Action

The resolution for Audi poor voice quality is straightforward and does not require any repairs to your vehicle. The TSB explicitly states that replacing parts or attempting repairs on the vehicle will not fix the problem and will not be covered under warranty.

To resolve this issue, you should check the iOS version on your Apple iPhone. If your device is running iOS 18.0.x through 18.4.x, you are advised to update it to iOS 18.5 or any newer version. This software update on your iPhone is expected to improve the voice quality during Bluetooth calls with your Audi.
