2019-2025 Audi Apple CarPlay / Android Auto Not Working TSB

Audi has issued Technical Service Bulletin (TSB) 2076466/1 to help technicians diagnose and resolve issues with Apple CarPlay and Android Auto in a wide range of 2019-2025 Audi models. This TSB, dated January 9, 2025, outlines a detailed troubleshooting process to address customer complaints about these popular smartphone integration features.

Symptoms

Owners may experience various complaints regarding Apple CarPlay or Android Auto, including the system not working properly. This can manifest as connectivity issues, apps not launching, or intermittent functionality. If you are experiencing an Audi e-tron Apple CarPlay not working issue, this TSB provides the diagnostic framework.

Technical Background

According to Audi, complaints related to Apple CarPlay and Android Auto can stem from several factors. These include incorrect MMI (Multi Media Interface) settings within the vehicle, specific phone settings, or limitations related to the phone's software version. It is crucial to ensure both the smartphone app and the phone's operating system are updated to their newest versions.

Troubleshooting Steps

Technicians are advised to follow a comprehensive checklist to pinpoint the cause of Apple CarPlay or Android Auto malfunctions. This process involves checking both the customer's smartphone and the vehicle's MMI system.

Phone and App Checks:

• Verify that Apple CarPlay is activated on the phone via "Settings => General => CarPlay".
• Confirm the Android Auto app is installed on Android devices.
• Check if Android Auto is officially available in the local country.
• Ensure the phone's operating system and relevant apps are running the latest software versions. For Apple CarPlay, iOS 15.5 (June 2022) or newer is recommended. For Android Auto, Android 5.0 or higher (with Android 8.0 or higher for wireless functionality) is required.
• Determine if resetting the phone or app to factory settings resolves the issue.
• Restart the iPhone or Android phone, especially for older iOS versions or reconnecting problems.

Vehicle and MMI System Checks:

• Confirm that a 5GHz network is permitted in the local market; if not, wireless Apple CarPlay (ASI) will not function.
• Note that for MIB2+ vehicles from model year 2019, wireless Apple CarPlay is not available and can only be used via USB.
• Check if privacy mode is deactivated on the MMI. If privacy mode is active, the 5 GHz Wi-Fi will be inactive, preventing wireless Apple CarPlay from working.
• Perform a terminal 30 reset of the control unit for information electronics (diagnostic address 5F) and the connectivity box/OCU (diagnostic address 75) by removing the relevant fuses. Remember to also check the backup battery.
• Verify the USB cable is not the cause of the issue by trying a different, genuine Audi Accessories USB cable. Also, check if the phone can charge via USB, which indicates a functional USB interface.
• If the Apple CarPlay tile does not respond, check for an established Wi-Fi connection. If a Bluetooth symbol is shown on the MMI, Wi-Fi is not active, and Apple CarPlay will not be available.

Reconnecting Devices:

• Completely reconnect the phone if necessary. This involves deleting the phone from the vehicle's "Phone menu => Device overview" and "ASI menu => Device overview" by pressing and holding the button to delete or reset to factory settings.
• On the iPhone, delete the MIB connection via "Settings => CarPlay => My Cars => Forget This Car".
• Restart the iPhone and then reconnect it to the MIB system.

Activation Codes:

• Ensure that activation codes have been run. If not, run them again using the "SVM activations" or "SVM activations (FoD)" test program, depending on the model. The activations are typically found in the control unit for information electronics (diagnostic address 5F) or the gateway (diagnostic address 19), depending on the model and MIB system.

If the Issue Persists

If the problem continues after performing all the above checks, and a technician can reproduce the complaint, a Technical Assistance Center (TAC) Ticket should be created. The ticket must include detailed information to assist in further diagnosis, such as:

• A video demonstrating the complaint, showing both the MMI and phone displays.
• Whether the issue occurs with both iPhone and Android phones.
• Specific phone models and iOS versions used.
• If the complaint occurred with previous iOS versions.
• Whether the customer's phone works in a comparable vehicle, including its VIN.
• A precise description of the conditions under which the complaint occurs, including whether it happens while driving, if specific messages are shown, Wi-Fi connection status, and if it's the first time CarPlay was activated in a bus cycle.
• Details on screen behavior (e.g., black screen) and if delays occur during wireless Apple CarPlay startup.
• A current diagnostic log.
• Information on what, if anything, resolves the issue (e.g., it resolves itself or after a certain period).

Important Warnings

Audi emphasizes that technicians must reproduce the customer complaint to accurately assign it to this TSB. Any repair based on this bulletin should only be carried out if all specified criteria (model, chassis number, engine/motor, gearbox code, PR number, part number, software version, etc.) apply exactly. Failure to do so may not resolve the problem, lead to repeat repairs, and could result in warranty claim rejection and redebiting of parts. This is particularly important for an Audi e-tron Apple CarPlay not working diagnosis.
