2023-2024 Audi ConBox High DTC B200096 B200000

Audi has issued Technical Service Bulletin (TSB) 91 24 09 2059528/9 to address specific diagnostic trouble codes (DTCs) that may appear in the telematics control module, also known as the ConBox High. This TSB, dated May 7, 2024, supersedes previous bulletin 24-93 from April 3, 2024, and provides updated procedures for diagnosing and resolving these issues.

This bulletin is particularly relevant for owners of various 2023-2024 Audi models, including the e-tron, A4, A5, A6, A7, A8, Q5, Q7, Q8, and their performance and e-quattro variants, who might encounter an "SOS malfunction warning" in their instrument cluster.

Symptoms

Owners may notice an "SOS malfunction warning" displayed prominently in the instrument cluster. This warning indicates a potential issue with the vehicle's emergency call system, which relies on the telematics control module.

Fault Codes / DTCs

Workshop findings indicate that the following diagnostic trouble codes (DTCs) may be stored in the telematics control module, J949 (address word 0075):

• DTC B200096: "Ctrl. Module Faulty" with symptom code 131077.
• DTC B200000: "Ctrl. Module Faulty" with symptom code 131096.

Diagnosis / Trigger Conditions

The TSB explains that these DTCs, B200096 and B200000, can be erroneously entered into the telematics control module under specific conditions. One common trigger is the removal of the vehicle's transport mode. Additionally, DTC B200000 can be stored if there was an aborted or incomplete software update to the ConBox High unit.

Technicians are advised to ensure they are using the most current ODIS version for diagnosis. The diagnostic process involves running the function "J949 – Control Module for Emergency Call Module and Communication Unit, check control module" for the J949 unit. This function can be accessed in ODIS via the path: Select Selftest > Body > Electrical Equipment > 01- On board diagnostic capable system > 0075 – Control Module for Emergency Call Module and Communication Unit - J949- > 0075 – Emergency Call Module, functions. Alternatively, it can be found through GFF by navigating to Control Modules > Right Click on 0075 – Emergency call module and communication unit -> Guided Functions.

Repair Procedure Summary

The primary repair procedure for the Audi e-tron ConBox High issue involves a diagnostic check and potential software re-update, rather than immediate part replacement. Technicians must first ensure their ODIS diagnostic software is up-to-date. Then, they will perform a specific diagnostic function for the J949 telematics control module. If DTC B200000 was triggered by an incomplete software update, the technician must verify the ConBox's software version and re-run the update if a discrepancy is found. Only after these diagnostic steps are completed should further action, such as part replacement, be considered.

Important Warnings

Audi has issued several critical warnings regarding this TSB:

• "Claims for replaced parts will not be reimbursed if the test plan from above was not attempted before replacement."
• "Claims for replaced ConBoxes, if required, should be invoiced outside of the scope of this TSB."
• If the ConBox was recently updated, technicians must confirm the update was successful by checking the software version. "If there is a discrepancy, please rerun the software update before following the instructions above."
• "If the vehicle is outside any warranty, this Technical Service Bulletin is informational only."
