2022-2024 Audi e-tron GT Software Update TSB 2073768/1

Important Warnings for Technicians and Owners

Audi TSB 2073768/1 outlines critical precautions that must be followed during this software update to prevent damage to high-voltage components and ensure a successful procedure:

• High-Voltage Charging Cable: To prevent the high-voltage battery from charging during the software update, the high-voltage charging cable on vehicles with high-voltage components must be unplugged BEFORE the SVM code SWVGTA001 is entered. Charging the high-voltage battery during a software update can cause damage to the high-voltage components.
• Battery Charger: It is recommended to use a battery charger with a current rating of at least 90A. The battery charger must be switched off and on once before beginning the update process.
• DoIP Communication: Always use DoIP (Diagnosis over Internet Protocol) when flashing a control module via ODIS in supported vehicles. To activate DoIP, navigate to Administration>>General>>GFF Process>>DoIP communication>>Only allow DoIP communication. This setting will automatically reset once the diagnostic session has ended.
• Applicability: This bulletin is only applicable if referred to by another TSB. When submitting warranty claims, both bulletins should be noted in the claim comments, or claims may be denied.
