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-A2N2U-052017-09-14. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM:RADIATOR ASSEMBLY; ELECTRICAL SYSTEM:WIRING. Concerns: Wire harness for rear left radiator fan Information: There is a possibility that the electric wire harness for the left rear radiator fan in the engine compartment is touching a heat guide plate made of carbon fiber on the affected vehicles. If the wire harness is touching, relative movements can cause visible damage to the wire harness or the insulation on individual lines of the wire harness. Progressive damage to the wire harness can cause the radiator fan to stop working and an electric shunt circuit to the low-resistance heat guide plate cannot be ruled out. This electric shunt circuit can cause the vehicle to go on fire even a long time after stopping the vehicle.
122-R9Q9K-052017-09-14. Service bulletin. ELECTRICAL SYSTEM. Concerns: Switching element for charge port door Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. Defective switching elements for the charge port doormay have been installed on the affected vehicles due to a supplier error. We have discovered that there is a greater likelihood that the switching elements used here will fail. If this is the case, the switching element can become mechanically blocked. It will then no longer be possible to open the charge port door.

EQUIPMENT:APPLIANCE:AIR CONDITIONER; ELECTRICAL SYSTEM:12V/24V/48V BATTERY; ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL; SUSPENSION:MULTIPLE AXLE. Concerns: Software update of the following control equipment and devices: * High-voltage battery * Air conditioning * Rear axle steering * DME control unit * PDK control unit * Porsche Communication Management (PCM) * Instrument cluster Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. New software is available for the specified control equipment and devices.
122-U5R2H-092016-10-04. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION; ELECTRICAL SYSTEM:WIRING:FUSES AND CIRCUIT BREAKERS. "THERE IS A POSSIBILITY THAT MOISTURE CAN GET INTO THE LID OF THE REAR FUSE BOX ON THE AFFECTED VEHICLES UNDER CERTAIN ENVIRONMENTAL INFLUENCES. THIS CAN CAUSE MALFUNCTIONS IN THE PDK TRANSMISSION OVER THE SERVICE LIFE OF THE VEHICLE. THE ERROR MESSAGE ""GEARBOX FAULT"" WILL THEN BE DISPLAYED IN THE INSTRUMENT CLUSTER AND THE TRANSMISSION WILL SWITCH TO THE REDUCED DRIVING PROGRAMME (LIMP-HOME MODE)."
