2021-2022 Audi CarPlay Blank Screen TSB

Owners of certain 2021-2022 Audi vehicles may experience issues with their Apple CarPlay system, specifically a blank screen and intermittent audio dropouts. Audi Technical Service Bulletin (TSB) 2065728/1, issued on January 14, 2022, provides information regarding this concern.

This TSB clarifies that the problem is not a fault with the vehicle's MMI system but rather an external software bug. The Audi e-tron CarPlay blank screen and related symptoms are attributed to a non-standard behavior in Apple's iOS.

Symptoms

Customers connecting an iPhone via wireless Apple CarPlay (wACP) to their vehicle's MMI system may observe the following:

• "Audio dropouts can be heard"
• "The ASI display goes blank."
• The shortcut bar on the left side of the screen and the top dropdown menu anchor remain visible, even when the main display area is blank.

No relevant Diagnostic Trouble Codes (DTCs) are stored in the vehicle's system when this issue occurs.

Technical Background

Audi has identified that the root cause of the blank Apple CarPlay screen and audio dropouts is a bug within the Apple iOS operating system. Specifically, current Apple iOS versions, including 14.x and 15.x, exhibit a behavior where the iPhone fails to send screen data correctly to the vehicle's MMI system. Apple is actively investigating this issue and is working on a solution to be released in a future iOS update.

Important Warnings for Owners

Audi has issued specific instructions for this issue:

• "Do not perform any repairs. Any repairs for this concern may be denied."
• "Please inform the customer that this behavior is due to a bug in the phone's operating system (iOS). Apple is currently analyzing the root cause of this behavior and is working on a solution that will be distributed with a future iOS update."

What Owners Should Know

Since the issue stems from the iPhone's operating system, there is no vehicle-specific repair available at this time. However, Audi suggests a few temporary workarounds that may resolve the Audi e-tron CarPlay blank screen or audio dropout issue:

• Temporary Reset: In some cases, navigating to the home menu by clicking the home shortcut on the left side of the screen and then re-entering the Audi Smartphone Integration (ASI) feature can resolve the problem.
• Reconnect Device: If the above step doesn't work, disconnecting and reconnecting the iPhone from the MMI system might be necessary.
• Keep iOS Updated: Audi advises customers to "always use the most current iOS software for iPhone to ensure the most up-to-date user experience." Future iOS updates are expected to contain the permanent fix from Apple.

Warranty Information

This Technical Service Bulletin (TSB 2065728/1) is informational only. It is not applicable to any Audi Warranty, as the issue originates from the customer's mobile device software rather than a vehicle component.

Required Parts and Tools

No specific parts or tools are required for this issue, as it is a software bug in the iPhone's operating system.
