122-T7Y5Q-122017-12-14. Service bulletin. ELECTRICAL SYSTEM. Information: This document updates information previously published in EQ 1105, EQ 1105, and EQ 1401. To provide stable voltage and sufficient current throughout certain service operations, you should connect the vehicle to a battery charger (sometimes referred to as a power supply). However, you may experience ECU programming and coding issues if the chosen battery charger has insufficient power. Many workshop manuals currently advise use of a battery charger with a 40 or 70 A current rating. However, with the increasing current requirements of modern Porsche vehicles, we recommend a battery charger capable of producing a minimum current of 90 A.
122-D5Y9G-102017-11-08. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ELECTRICAL SYSTEM. The sport exhaust system can be activated/deactivated by pressing the button with the "Twin tailpipe" symbol. The sport exhaust system is also active in "Sport" or "SportPlus" mode. Here, the sports exhaust system can be switched off or even switched on again using the "Twin tailpipe" button. The switch console (combined switch) is a repair kit and must also be ordered. The repair kit contains the main body, the required buttons and the trims. The new switch console is assembled in accordance with the new vehicle equipment. Engine power and exhaust behavior of the vehicle are not affected. The sport exhaust system is also available ex-works for new vehicles by requesting optional equipment XLF or XLX.

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-102017-10-15. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; ELECTRICAL SYSTEM. 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.
