No. 139-202020-10-01. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Information on replacing the HV battery on the Panamera S E Hybrid.
122-Z6W8C-072017-10-27. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Subject: Discharge protection function of the batterymanagement system(BMS) in order to extend the service life of high-voltage and low-voltage batteries
122-X3Y7Q-072017-10-27. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Concerns: AGM starter battery (referred to below simply as 'battery') Situation: Support for the care andmaintenance of the AGMstarter battery (at the dealership): From the time the vehicle is delivered to the Porsche Centre until it is handed over to the customer, the battery must be maintained and charged regularly, depending on use.
122-R8X7Z-072017-10-27. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Customer complaints concerning battery-related topics Recurring customer complaints concerning topics relating to battery capacity and quality.
122-B7U4T-052017-10-15. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Customer Concern: Certain vehicle systems have unwanted, unpredictable behavior. Technical Concern: The symptoms are difficult to diagnose. There may be multiple symptoms intermittently affecting multiple systems. Though this is not an exhaustive list, some common failure modes are: ? Start/stop issues ? Power windows not fully returning to the parked position after automatic preopening ? PCM audio stopping during a start/stop cycle Ultimately, the technician determines that low 12-volt battery voltage is the underlying root cause of the unwanted behavior. The technician corrects the battery?s low voltage. Consequently, the unwanted behavior ends.
