2022 Audi e-tron GT Audi Connect Not Functioning TSB

Owners of 2022 Audi e-tron GT and RS e-tron GT vehicles may experience problems with their Audi Connect services after the 91DZ campaign has been completed. This Technical Service Bulletin (TSB) 91 23 29 2068824/2, which supersedes TSB Group 91 number 22-56, details the cause and the necessary repair for this condition. The primary symptom is that the 2022 Audi e-tron GT Audi Connect services, including those in the MMI and the myAudi app, no longer function.

Symptoms

If your 2022 Audi e-tron GT Audi Connect services are not working after the 91DZ campaign, you may notice the following:

• "Audi connect services in the MMI and the myAudi app no longer function"
• The SOS button LED is not green; it may appear "RED or OFF".

Diagnosis / Trigger Conditions

The root cause of the 2022 Audi e-tron GT Audi Connect malfunction stems from the 91DZ campaign. This campaign involves updates to three key control modules: the Infotainment control module (J794), the On-Board Diagnostic Interface control module (J533), and the ConBox control module (J949). After these updates, a new software coding container is assigned to each control unit.

The problem arises when an incorrect coding container is given to the On-Board Diagnostic Interface control module (J533). This incorrect coding prevents Audi Connect services from functioning correctly. Additionally, early-built e-tron GT vehicles produced before calendar week 36 of 2021 used an older Audi Connect backend server. While all newer vehicles use a newer backend, the coding in the J533 module determines which backend the vehicle attempts to use. For these specific early-built vehicles, the older backend server is still required, which then redirects communication to the newer backend.

Repair Procedure Summary

The repair outlined in Technical Service Bulletin 91 23 29 2068824/2 focuses on correctly coding the On-Board Diagnostic Interface control module (J533). Manual coding of the J533 module is no longer necessary.

The long-term solution involves using the ODIS diagnostic system to automatically code the J533 module. The process is as follows:

1. Start the ODIS software and select the Guided Fault Finding (GFF) function.
2. Once all vehicle modules have loaded, right-click on Diagnostic Address 0019 – Data Bus On-Board Diagnostic Interface (J533).
3. Select "Guided Functions" from the context menu.
4. Choose "SVM Check Module Configuration" to initiate the automatic coding process.

If the Audi Connect system continues to malfunction after this procedure, technicians are instructed to open a ticket with the Digital Business Support team via the web ticketing system at https://audi.zendesk.com.
