2021 Audi SOS Malfunction Warning TSB

Owners of certain 2021 Audi models may encounter an unexpected Audi e-tron SOS malfunction warning appearing in their vehicle's instrument cluster. This warning is often accompanied by specific diagnostic trouble codes (DTCs) related to the telematics control module.

Audi has released Technical Service Bulletin (TSB) 2059528/2 to address this issue. The TSB provides a detailed procedure for dealerships to diagnose and resolve the problem, which typically involves erroneous DTC entries during the removal of transport mode.

Symptoms

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

Fault codes / DTCs

When diagnosing this issue, technicians will typically find one of the following diagnostic trouble codes stored in the telematics control module, identified as J949 (address word 0075):

Code	Description	Module
B200096	Ctrl. Module Faulty (with symptom code 131077)	Telematics control module J949
B200000	Ctrl. Module Faulty (with symptom code 131096)	Telematics control module J949

These codes suggest an internal fault within the control module, even if the module itself is not physically damaged. The technical background explains that these DTCs can be erroneously generated when the vehicle is taken out of transport mode.

What the service bulletin says

Technical Service Bulletin 2059528/2, which supersedes TSB 20-67, outlines a specific diagnostic and repair process. The bulletin instructs technicians to use the most current version of the ODIS diagnostic software, specifically ODIS 5.2.6 with GFF 2.20.1 or newer.

The procedure involves running a Guided Fault Finding (GFF) test plan for the telematics control module J949. Crucially, the bulletin states that the test plan should be followed to clear the DTCs without actually replacing the telematics control module part. If the DTCs persist after this procedure, technicians are advised to open an ODIS feedback ticket for further assistance.

What to do

If your 2021 Audi is displaying an Audi e-tron SOS malfunction warning or you suspect your vehicle is affected by DTC B200096 or B200000, it is recommended to schedule an appointment with an authorized Audi dealership. Explain the symptoms and mention the possibility of this specific technical service bulletin (TSB 2059528/2).

The dealership technicians have access to the necessary diagnostic tools and procedures to address this issue correctly. They will be able to perform the required software updates and diagnostic steps to clear the fault codes without unnecessary part replacement.
