2023-2024 Audi MIB3 Apple CarPlay Blank Screen TSB

Owners of 2023-2024 Audi vehicles equipped with the MIB3 system and Audi Smartphone Interface may encounter a situation where their Apple CarPlay screen appears blank. This issue, detailed in Audi Technical Service Bulletin 2065728/5, has specific causes depending on the iPhone model and iOS version being used.

Symptoms of a Blank Apple CarPlay Screen

The primary symptom is the "Apple CarPlay screen is blank" or the "ASI display is blank when using wACP" (wireless Apple CarPlay). This means that despite your iPhone being connected, no content is displayed on the vehicle's infotainment screen when using CarPlay.

No Fault Codes Stored

Audi's workshop findings indicate that when this Audi CarPlay blank screen condition occurs, there are "No relevant DTCs are stored". This means diagnostic trouble codes will not be present to help identify the problem, as the issue stems from external device compatibility rather than a vehicle system fault.

Technical Background: Why Your Screen is Blank

The TSB explains that the blank screen can be caused by a non-standard behavior in certain Apple iOS versions. Specifically, iOS 14.x, 15.x, and most 16.x versions may prevent the phone from sending screen data correctly to the vehicle. This is identified as a bug in the phone's operating system.

Additionally, a hardware issue within the WiFi chipset of specific older iPhone models—iPhone 8, iPhone X, and iPhone XR—can also cause the display to blank out. These older iPhone models are out of production, and no repair is available for this hardware limitation.

Important Warnings and Owner Actions

Audi has issued several important advisories regarding this Audi CarPlay blank screen issue:

• "Do not perform any repairs. Any repairs for this concern may be denied." This TSB is informational, and there is no vehicle-side repair for this condition.
• "No repair will be available" for iPhone 8, iPhone X, and iPhone XR models due to their hardware limitations.
• "Please ask the customer to always use the most current iOS software for iPhone to ensure the most up-to-date user experience." Keeping your iPhone's operating system updated is crucial.
• This TSB is "informational only and not applicable to any Audi Warranty." Costs related to this issue are not covered under Audi's warranty.

Recommended Solutions for Owners

The solutions depend on the iPhone model you are using:

• For customers with iPhone 8, iPhone X, and iPhone XR: Due to a hardware issue in the WiFi chipset of these older, out-of-production phone models, a wireless connection may not work reliably. It is "advisable to use a wired connection to use Apple CarPlay" for these models.
• For all other iPhone models: The blank screen is typically due to a bug in the phone's operating system (iOS). This bug is fixed in "iOS version 16.5 or newer". Updating your iPhone to the latest iOS version is recommended.

In some cases, a temporary workaround might resolve the issue. You can try going to the home menu by clicking the home shortcut on the left of the screen and then reentering the Audi Smartphone Interface (ASI). Alternatively, disconnecting and then reconnecting your phone might also help.
