| 122-S7H6V-03 | 2018-03-13. Service bulletin. Concerns: Battery trickle charging with "Charge-o-mat"may time out within a short period of time. The trickle charging will thus end prematurely. Thismay result in a dead battery. Information: The ?Charge-o-mat? device recommended by Porsche can be connected to the plug socket in the above-mentioned vehicles again in accordance with instructions in order to trickle-charge the battery (e.g. in the showroom) if: ? the gateway control unit is re-coded beforehand using the PIWIS Tester with test software version 36.800.030 installed. |

| 122-X3Y7Q-07 | 2017-10-27. Service bulletin. 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-W4G8S-10 | 2017-10-15. Service bulletin. Technical Concern: By design, the vehicle gateway allows certain vehicle features to time-out, in stages. This allows the vehicle to sleep. One feature that can time-out is the 12 V DC power point (cigarette lighter) in the center console area. One of the recommended methods of using the battery maintainer is to plug the battery maintainer into this power point. If this power point becomes disabled, it will not allow current flow from the battery maintainer to the vehicle, the vehicle battery will not trickle charge, and the battery maintainer will eventually shut off. |
| 122-B7U4T-05 | 2017-10-15. Service bulletin. 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. |
