Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Audi e-tron · 2021–2021
Audi TSB 2061788/2 covers model-year 2021 e-tron quattro and e-tron Sportback vehicles with specified AC/DC charging interruptions, charging-flap operation problems, or an app request for auxiliary heating that does not pre-heat the vehicle when matching DTCs are stored in high-voltage battery charger control module J1050. Audi attributes the documented condition to onboard-charger software and identifies old software level 0070, not a proven failed charger module.
Common Symptoms
- AC or DC charging is interrupted
- DC charging does not start or stops at some stations
- Charging-flap button is inoperative or the flap does not open
- Auxiliary heating is activated through the app but the vehicle does not pre-heat
How to Fix
Record whether the failure is AC, DC or station-specific and have J1050 scanned before parts. If the vehicle has the matching condition and software level 0070, Audi directs an SVM update to software 0079 or higher. After the update, reproduce the concern and follow the guided test plan for any new active DTC. Do not infer hardware failure merely because one charging mode works, and do not order the former charger, 12-volt battery, relay, meter or portable EVSE from this card.
Owner tips & cautions
- TipBring the failed station, date and charging mode to the diagnosis and ask for the J1050 software level and full DTC list before authorizing hardware.
