- Electrical system: software
- Summary
- Concerns: High-voltage battery control unit Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. New software for the high-voltage battery control unit is available for the affected vehicles. This software improves or corrects the following: The temperature of the high-voltage battery is monitored by two temperature sensors for each cell module. The current diagnostic setup of the high-voltage system does not allow for this redundancy and causes the warning message "Hybrid system failure - Park vehicle safely" to be displayed in the instrument cluster if one temperature sensor fails even though the temperature of the cell module is still monitored reliably by the remaining sensor.
