2024 Audi Wireless CarPlay/Android Auto Inop Fix TSB

Audi has issued Technical Service Bulletin (TSB) 91 24 95 2073333/3 to address concerns regarding the wireless Audi Smartphone Interface (ASI), which includes Apple CarPlay (ACP) and Android Auto (AA), in various 2024 Audi models. This bulletin, dated April 4, 2024, supersedes previous TSB 24-88 from March 22, 2024, and provides updated service and warranty information.

This TSB specifically targets situations where the wireless smartphone interface is inoperative, preventing owners from connecting their phones wirelessly. If you own a 2024 Audi Q8 wireless CarPlay system that isn't working, this information is highly relevant.

Symptoms

Owners of affected 2024 Audi vehicles may experience the following issues with their smartphone interface:

• "The Audi Smartphone Interface [ASI] (Apple CarPlay [ACP] / AndroidAuto [AA]) cannot be paired to the phone wirelessly."
• "The phone tiles under the ASI menu are grayed out" in the infotainment system display.

It's important to note that if a wired ASI connection is used, the system typically functions as expected. Additionally, workshop diagnostics will often show no relevant Diagnostic Trouble Codes (DTCs) stored, and the vehicle's 5GHz Wi-Fi network may not be broadcasting.

Important Warnings

Audi explicitly states in this TSB:

"Parts replacement does not solve this issue. Claims for replaced parts will be subject to review."

This means that attempting to replace components to resolve the inoperative wireless smartphone interface will not fix the problem and may lead to warranty claims being denied. The issue is a configuration problem, not a hardware failure.

Technical Background

The wireless Audi Smartphone Interface relies on the vehicle's 5GHz Wi-Fi network to establish communication and stream content from a smartphone to the Multi Media Interface (MMI). The root cause of the problem is a configuration issue that can prevent this crucial 5GHz Wi-Fi network from being available in certain vehicles. This directly impacts the functionality of the wireless ASI, including the Audi Q8 wireless CarPlay feature.

Repair Procedure Summary

To resolve the inoperative wireless Audi Smartphone Interface, technicians should follow these steps outlined in TSB 91 24 95 2073333/3:

1. Execute Diagnostic Test Plan: Access the Guided Functions and run the "Check control module configuration" test plan for the Emergency Call Module and Communication Unit (ConBox) -J949- (address word 0075).
2. Delete Existing Connections: Remove all previously paired Audi Smartphone Interface (ASI) connections from the vehicle's system.
3. Re-establish Functionality: Allow the vehicle to complete a bus sleep cycle. After this cycle, the correct functionality of the wireless smartphone interface should be re-established.

For Certified Pre-Owned (CPO) vehicles, the claim type is G10, requiring owner verification. If the vehicle is outside of these warranty parameters, the TSB serves as informational guidance only.
