2022-2024 Audi SOS Emergency Call Warning TSB

Owners of certain 2022-2024 Audi vehicles equipped with ConBox High may encounter an "Emergency call function: fault" warning message in their instrument cluster. This Technical Service Bulletin (TSB) 2076052/1, also identified as 91 PSS ConBox High, details the condition and Audi's current approach to this issue.

The Audi SOS emergency call warning indicates that the emergency call function is restricted or unavailable. While this warning is concerning, Audi states that the issue is under analysis, and no immediate repairs are necessary.

Symptoms

Owners will observe the following warning message displayed in the instrument cluster:

• "Emergency call function: fault. Function restricted. Please contact workshop."
• "SOS Emergency call function: fault. Function unavailable. Please contact workshop"

This Audi SOS emergency call warning message is typically not permanent. It often disappears after cycling the ignition off and on again, or after a bus sleep cycle.

Fault Codes / DTCs

While no static Diagnostic Trouble Codes (DTCs) are typically stored in the emergency call module control unit and communication unit (-J949-), intermittent DTCs may be found in the data bus diagnostic interface (-J533-):

• U142100: Control module for emergency call module and communication unit no communication - sporadic.
• U164200: Ethernet Emergency Call Module no communication - sporadic.

Important Warnings for Owners

Audi has provided critical guidance regarding this issue:

• "Do not replace any components for this condition since this will not resolve the customer's concern."
• "Replacing parts or attempting repairs will not fix the problem. Unjustified labor/replacement parts will be charged back. Invoicing under warranty is not permitted for this issue."

These warnings emphasize that replacing components related to the emergency call system will not resolve the underlying problem and may result in charges to the owner or dealer.

Diagnosis and Trigger Conditions

Workshop findings confirm that the customer complaint can be reproduced. The intermittent nature of the warning and associated DTCs suggests a complex electrical or software interaction within the vehicle's communication systems. The issue specifically affects vehicles with ConBox High.

Repair Procedure Summary

As of the release of TSB 2076052/1 (November 21, 2024), the issue causing the Audi SOS emergency call warning is still under analysis by Audi. The analysis is expected to be completed by the end of the first quarter of 2025, though this timeline is subject to change. Currently, no permanent repair measure is available.

In some cases, a temporary workaround involves performing a terminal 30 reset of the emergency call module control unit and communication unit (-J949-). However, this is not a permanent fix.

Owner Action

If you experience the "Emergency call function: fault" warning in your 2022-2024 Audi, you should contact your authorized Audi dealership. Technicians are instructed to explain that the issue is under analysis and that no repairs are currently necessary. They will create a Pending Service Solutions (PSS) record in the PSS application through AccessAudi. This record helps Audi track the prevalence of the issue while they work on a definitive solution.

This Technical Service Bulletin is informational, particularly if the vehicle is outside of warranty. The Service Number associated with this condition is 9145, and the Damage Code is 0039.
