2023-2025 Audi Wireless Smartphone Interface Inop TSB

Audi has issued Technical Service Bulletin (TSB) 2073333/5 to address a common problem affecting the wireless Audi Smartphone Interface (ASI), which includes Apple CarPlay (ACP) and Android Auto (AA), in various 2023-2025 models. This TSB, dated June 17, 2024, supersedes an earlier bulletin, Group 91 number 24-00, from April 15, 2024.

The TSB focuses on situations where the Audi wireless Smartphone Interface inop condition prevents wireless connection to mobile devices. This issue specifically impacts the wireless functionality, while a wired connection for ASI continues to work as expected.

Symptoms

Owners of affected Audi vehicles may experience the following:

• "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."

Diagnosis / Trigger Conditions

When diagnosing this issue, technicians have noted that no relevant Diagnostic Trouble Codes (DTCs) are stored in the vehicle's system. The core problem is that the vehicle's 5GHz Wi-Fi network, which is essential for the wireless Audi Smartphone Interface to function, is not being broadcast. This configuration issue prevents the wireless ASI from operating correctly, even though a wired connection works without problems.

Important Warnings

Audi explicitly states in the TSB:

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

This means that replacing components related to the Audi Smartphone Interface will not resolve the underlying configuration problem and will not be covered under warranty if attempted.

Repair Procedure Summary

To resolve the Audi wireless Smartphone Interface inop condition, technicians should perform the following steps:

1. Execute Test Plan: Run the "Check control module configuration" test plan. This is found under Guided Functions for the Emergency Call Module and Communication Unit (ConBox) -J949-, specifically at address word 0075.
2. Delete Connections: Remove all existing Audi Smartphone Interface (ASI) connections from the vehicle's system.
3. Bus Sleep Cycle: Allow the vehicle to complete a bus sleep cycle. After this, the correct functionality of the wireless ASI should be reestablished.
