An official CAA Japan notice concerns Passenger car (Audi e-tron) - Repair. Defect in electrical equipment (high-voltage battery). ■ Defective part (component name): Electrical equipment (high-voltage battery). ■ Condition and cause of the structure, equipment or performance considered noncompliant with standards: In the high-voltage battery, inappropriate manufacturing tolerance settings for the cell modules have resulted in some cell modules with large tolerances. Consequently, irregularities in charging and discharging characteristics may occur under certain conditions. If the charge levels of the affected cell modules and the battery are in the upper range, the battery may overheat during discharge for cell balancing control and, in the worst case, cause a fire. Published 2024-03-22.
What to do now
(Recall notification number) 外-3785 ■ Corrective measures: Update all vehicles with the corrective software. However, because preparation of the software will take time, inspect the high-voltage battery and replace battery modules with nondefective ones if necessary. As an interim measure, limit the charge level to ８０％ and inspect the battery regularly (every ４ months).
