Service bulletins for the 2017 Porsche 718 Cayman

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

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-J5M3M-112017-12-14. Service bulletin. ENGINE AND ENGINE COOLING. Concern: Vehicle is stored for a long period of time in the sun and heat, typically 30 days or more. Several cases of compressors seizing have occurred at PDI. Please use the procedure below during the PDI as a precaution.

122-J5J5B-102017-11-08. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION. During diagnostic monitoring of the hydraulic control valves of the PDK transmission, a fault memory entry is stored in the PDK control unit if an implausible shift rod movement is detected. The PDK control unit therefore initiates a flushing measure in order to flush particles of dirt determined as the cause of the fault out of the hydraulic control valves. As soon as the fault memory entry was activated in two consecutive driving cycles, there was a possibility with the previous diagnostic configuration that the message "Engine control fault ? visit workshop ? Driving permitted" would be displayed in the instrument cluster although the flushing measure had already been carried out successfully and a fault was no longer present. To prevent this from happening, the diagnostic function for monitoring the hydraulic control valves will be adapted accordingly.
122-N9Z4L-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.
