2021-2022 Audi SOS Malfunction Warning TSB

Audi has released Technical Service Bulletin (TSB) 2059528/4 to address an "SOS malfunction warning" displayed in the instrument cluster of various 2021-2022 Audi models. This issue is typically linked to diagnostic trouble codes (DTCs) B200096 or B200000 stored in the telematics control module, also known as J949 or ConBox.

This TSB provides a specific diagnostic and repair procedure for technicians to resolve the Audi e-tron SOS malfunction and clear the associated fault codes.

Symptoms

Owners of affected 2021-2022 Audi vehicles may observe the following symptom:

• "SOS malfunction warning" displayed in the instrument cluster.

Fault Codes / DTCs

When diagnosing the "SOS malfunction warning", technicians may find the following 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 diagnostic trouble codes (DTCs) can be stored erroneously in the telematics control module (J949) under certain conditions. One common scenario is when the vehicle is removed from transport mode.

Additionally, DTC B200000 specifically can be triggered if an attempted software update for the ConBox is aborted or incomplete. In such cases, the module's software version may not match the expected version, leading to the fault.

Important Warnings

Owners and technicians should be aware of the following critical information:

• "Claims for replaced parts will not be reimbursed if the replacement test plan (step 3) was not attempted before replacement."
• "The DTC B200000 can enter into the control module after an aborted or incomplete software update of the ConBox." If a ConBox update recently occurred, technicians must verify the software version and rerun the update if there's a discrepancy before proceeding with other diagnostic steps.

Repair Procedure Summary

The repair procedure for the Audi e-tron SOS malfunction primarily involves using the ODIS diagnostic system to clear the fault codes. The steps are as follows:

1. Update ODIS Version: Ensure the diagnostic system is running the most current ODIS version, with a minimum requirement of ODIS 5.2.6 and GFF 2.20.
2. Run GFF: Execute the Guided Functions (GFF) in ODIS. This will initiate a parts replacement test plan specifically for the telematics control module, J949.
3. Attempt DTC Clear: Follow the instructions of the parts replacement test plan without actually replacing the telematics control module. This procedure is designed to clear the DTCs.
4. Module Replacement (If Necessary): If the initial procedure fails to clear the fault codes, then the telematics control module, J949, should be replaced.
5. ConBox Software Check (for B200000): If DTC B200000 is present and the ConBox recently received a software update, confirm that the software version matches the expected new version. If a mismatch is found, rerun the software update before attempting steps 1-3.

Required Tools and Parts

To perform this repair, technicians will need:

• ODIS diagnostic system (minimum version 5.2.6 with GFF 2.20).
• Fasteners, bolts, nuts, and screws as specified in ETKA/ELSA for the repair manual.
• Telematics Control Module (if replacement is necessary), as specified in ETKA.
