2019-2025 Audi Apple CarPlay / Android Auto Issues TSB

Symptoms

Owners of various 2019-2025 Audi models may experience a range of complaints regarding their in-vehicle smartphone integration systems. The primary symptom is that "Apple CarPlay or Android Auto is not working properly." This can manifest as the system not connecting, intermittent functionality, or a complete failure to launch.

Technical Background

Audi has identified that issues with Apple CarPlay and Android Auto can stem from several sources. These include incorrect MMI (Multi Media Interface) settings within the vehicle, specific settings on the owner's smartphone, or limitations related to the phone's operating system software. Audi recommends always ensuring both the smartphone app and the phone's operating system are running the newest available software version to rule out common software-related conflicts.

Important Warnings

Audi emphasizes the importance of proper diagnosis before attempting any repairs. The Technical Service Bulletin 2076466/1 states:

"Try to reproduce the customer complaint (based on the description/cause of the issue), so that it can be clearly assigned to this TSB. The following repair must only be carried out if all the criteria (model/type, chassis number, engine/motor and gearbox code, PR number(s), part number, software version, code etc.) apply exactly. Otherwise, this solution will not eliminate the problem, and repeat repairs may be necessary. In such a case, we may reject the warranty claim and redebit the parts."

This means that technicians must thoroughly investigate and confirm the root cause according to the TSB's guidelines to ensure the repair is effective and covered under warranty. Owners should be aware that unauthorized or incorrect repairs may not be covered.

Diagnostic Steps for Technicians

This TSB provides a comprehensive checklist for technicians to diagnose issues with Apple CarPlay and Android Auto. These steps aim to identify whether the problem lies with the phone, the vehicle's MMI system, or connectivity:

Phone and Software Checks

• Verify if Apple CarPlay is activated on the phone (Settings => General => CarPlay).
• Confirm the Android Auto app is installed on Android devices.
• Check if Android Auto is available in the vehicle's country.
• Ensure the phone has the latest software version installed. For Apple CarPlay, iOS 15.5 (June 2022) or newer is required. For Android Auto, Android 5.0 or higher (8.0 for wireless) is needed.
• Determine if a 5GHz network is permitted in the market; if not, wireless ASI (Audi Smartphone Interface) may not be possible.
• For MIB2+ vehicles from model year 2019, note that "Wireless Apple CarPlay is not available for these vehicles; Apple CarPlay can only be used via USB."

MMI and Connectivity Checks

• Check if privacy mode is deactivated on the MMI. If privacy mode is active, the 5 GHz Wi-Fi will not be active, preventing wireless Apple CarPlay functionality.
• 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 relevant fuses and disconnecting the backup battery.
• Verify the USB cable by trying a different, genuine Audi USB cable.
• Check if the phone can charge via USB; if not, inspect the USB interface.
• If there is no response when pressing the Apple CarPlay tile, confirm a Wi-Fi connection has been established. If a Bluetooth symbol is shown on the MMI, Wi-Fi is not active.

Phone and MMI Resets/Reconnects

• Attempt to resolve the issue by resetting the phone/app to factory settings.
• Restart the iPhone or Android phone.
• Run activation codes via GFF (Guided Functions) using "SVM activations" or "SVM activations (FoD)". These activations are for the control unit for information electronics (diagnostic address 5F) or the gateway (diagnostic address 19).
• Completely reconnect the phone by deleting it from the MIB's device overview, resetting ASI to factory settings, selecting "Forget This Car" in the iPhone's CarPlay settings, restarting the iPhone, and then reconnecting.

Advanced Troubleshooting (if issue persists)

If these initial checks do not resolve the problem, technicians are instructed to create a TAC Ticket. This ticket must include detailed information such as a video of the complaint, whether the issue occurs with both iPhone and Android, specific phone models and iOS versions used, and precise conditions under which the complaint occurs (e.g., while driving, after bus sleep mode, Wi-Fi connection quality, black screen details, diagnostic log).

Repair Procedure Summary

This TSB, identified as 91 25 00 2076466/1, primarily focuses on diagnostic and software-related solutions rather than physical component replacement. The labor operations associated with this bulletin include:

• Check display and operating unit control unit (remove fuse): This involves checking the functionality of the MMI display and control unit, potentially requiring a fuse removal as part of the diagnostic process (Labor Operation 9196 0199, 20 TU).
• GFF / Guided Functions: Technicians will utilize guided diagnostic functions to pinpoint issues, with time recorded as per the diagnostic protocol (Labor Operation 0150 0060).
• Charge battery: Ensuring the vehicle's battery is adequately charged is a preliminary step for stable system operation (Labor Operation 2706 8950).
• Check and adjust display and operating unit control unit: This involves further checks and potential adjustments to the MMI display and control unit (Labor Operation 9196 0599, 20 TU).

These steps are designed to systematically troubleshoot and, if necessary, re-initialize the vehicle's infotainment system and its connection to external devices.

Warranty Information

For vehicles still under warranty, claims related to this issue must adhere to the Audi Warranty Policies and Procedures Manual. The Service Number for this TSB is 9109, and the Damage Code is 0040. The claim comment should reference "As per TSB 2076466/1". If the vehicle is outside of its warranty period, this Technical Service Bulletin is for informational purposes only, and any repairs would typically be at the owner's expense. All warranty claims are subject to review and audit by Audi Warranty.

Owner Action

If you are experiencing issues with Apple CarPlay or Android Auto in your 2019-2025 Audi, such as your 2023 Audi e-tron Apple CarPlay not working, consider these initial steps:

• Update your phone: Ensure your smartphone's operating system (iOS 15.5+ or Android 5.0+/8.0 for wireless) and the Apple CarPlay/Android Auto apps are fully updated.
• Check phone settings: Verify that Apple CarPlay is enabled on your iPhone and that Android Auto is installed and configured correctly on your Android device.
• USB cable: Try using a different, genuine USB cable if you typically connect via wired CarPlay/Android Auto.
• Restart devices: Restart both your smartphone and your vehicle's MMI system.
• Privacy Mode: Check your MMI settings to ensure privacy mode is deactivated, as this can disable 5 GHz Wi-Fi and prevent wireless CarPlay.

If the problem persists after these checks, contact your authorized Audi dealership. Inform them about the specific symptoms and mention Technical Service Bulletin 2076466/1. Be prepared to provide details about your phone model, software version, and the conditions under which the issue occurs, as this will assist technicians in their diagnostic process.
