2021-2022 Audi SOS Malfunction Telematics Module TSB

Owners of various 2021-2022 Audi models may encounter an "SOS malfunction warning" displayed in their instrument cluster. This warning is typically linked to Diagnostic Trouble Codes (DTCs) B200096 or B200000 being stored in the telematics control module, also known as the ConBox or J949.

This Technical Service Bulletin (TSB) 2059528/5, released on February 23, 2022, provides diagnostic and repair procedures for this specific issue. It supersedes a previous bulletin, Group 91 number 22-72, dated January 31, 2022, with updated service procedures and added model years.

Symptoms

The primary symptom owners will notice is an "SOS malfunction warning" displayed prominently in the vehicle's instrument cluster. This indicates a potential issue with the emergency call system.

Fault Codes / DTCs

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

Code	Description	Symptom Code
B200096	Ctrl. Module Faulty	131077
B200000	Ctrl. Module Faulty	131096

Technical Background

These DTCs, B200096 or B200000, can be erroneously stored in the telematics control module. One common cause is when the vehicle's transport mode is removed, leading to an incorrect entry of the DTCs.

Additionally, DTC B200000 can also appear if a software update for the ConBox was aborted or incomplete. Ensuring successful software updates is crucial to prevent this specific fault.

Important Notes for Owners

If your vehicle has recently undergone a ConBox software update and you are experiencing the "SOS malfunction warning" with DTC B200000, it's important to confirm the update was successful. If there's any discrepancy, the software update should be rerun before proceeding with other diagnostic steps.

For warranty claims involving a replaced telematics control module, Audi specifies that reimbursement will not be issued if the diagnostic test plan (Step 2 of the repair procedure) was not attempted prior to the part replacement. This ensures proper diagnostic protocols are followed.
