2021-2026 Audi MIB3 Apple CarPlay Blank Screen TSB

Symptoms

Owners of 2021-2026 Audi vehicles equipped with MIB3 and Apple CarPlay may experience the following issues:

• An iPhone is connected via wireless Apple CarPlay (wACP) to the vehicle's MMI system.
• The Audi Smartphone Integration (ASI) feature is selected in the vehicle.
• "Audio dropouts" can be heard.
• "The ASI display goes blank." While the main display is blank, the shortcut bar on the left side of the screen and the top dropdown menu anchor may still be visible.

When these symptoms occur, workshop findings indicate that "No relevant DTCs are stored."

Technical Background

Audi's Technical Service Bulletin 91 23 51 2065728/6 explains that the Audi MIB3 Apple CarPlay blank screen issue can arise from two primary causes:

1. iOS Software Bug: A non-standard behavior in previous Apple iOS versions (including all 14.x, 15.x, and early 16.x versions) prevents the iPhone from properly sending screen data to the vehicle's MMI system. This bug has been addressed and is fixed in iOS version 16.5 or newer.
2. iPhone Hardware Issue: A hardware problem within the WiFi chipset of specific older iPhone models—namely the iPhone 8, iPhone X, and iPhone XR—can also cause the display to blank out. These phone models are no longer in production.

Important Warnings and Owner Information

Audi has issued several key advisories regarding this Audi MIB3 Apple CarPlay blank screen concern:

• No Repair Available: "No repair is available at this time." Technicians are instructed, "Do not perform any repairs. Any repairs for this concern may be denied."
• Warranty Information: "This TSB is informational only and not applicable to any Audi Warranty."
• Software Updates: Owners are advised, "Please ask the customer to always use the most current iOS software for iPhone to ensure the most up-to-date user experience." Ensuring your iPhone is running iOS 16.5 or newer is crucial for resolving the software-related aspect of this problem.
• Temporary Workarounds: In some cases, navigating to the home menu by clicking the home shortcut on the left side of the screen and then reentering ASI may resolve the concern. Alternatively, disconnecting and reconnecting the phone might be necessary.

Repair Procedure Summary

Since no traditional repair is available for the Audi MIB3 Apple CarPlay blank screen issue, the recommended actions depend on the iPhone model:

• For customers with iPhone 8, iPhone X, and iPhone XR: The problem is attributed to a hardware issue in the WiFi chipset of these specific phone models. As these models are out of production, no repair will be provided. Owners of these devices are advised to use a wired connection to utilize Apple CarPlay functionality.
• For all other iPhone models: Inform the customer that the behavior is due to a bug in the phone's operating system (iOS). This iOS bug is fixed in iOS version 16.5 or newer. Updating the iPhone to the latest iOS version is the recommended solution.
