Symptoms

The primary symptom owners will notice is an "SOS malfunction warning" message appearing in the instrument cluster. This warning indicates a problem with the vehicle's emergency call system.

Fault Codes / DTCs

When diagnosing the "Audi SOS malfunction warning", technicians may find the following Diagnostic Trouble Codes (DTCs) stored in the telematics control module (J949, address word 0075):

Diagnosis / Trigger Conditions

These DTCs, B200096 and B200000, can be erroneously stored in the telematics control module, also known as the ConBox. This often occurs when the vehicle is removed from transport mode. Additionally, DTC B200000 can appear if a software update to the ConBox was aborted or incomplete.

Repair Procedure Summary

To resolve the "Audi SOS malfunction warning", technicians should follow a specific diagnostic and repair process:

1. ODIS Version Check: Ensure the most current version of the ODIS diagnostic software is being used.
2. Diagnostic Function Run: Execute the ODIS function "J949 – Control Module for Emergency Call Module and Communication Unit, check control module" for the J949 unit. This function can be found in ODIS by navigating to: Select Selftest > Body > Electrical Equipment > 01-On board diagnostic capable system > 0075 – Control Module for Emergency Call Module and Communication Unit -J949- > 0075 – Electrical components.
3. Module Replacement: If the diagnostic procedure fails to clear the fault, the telematics control module (J949) should be replaced.
4. Software Update Verification: If DTC B200000 is present and the ConBox was recently updated, technicians must confirm the update was successful by checking the ConBox's software version. If there's a discrepancy, the software update should be rerun before proceeding with steps 1-3.
