Service bulletins for the 2017 Porsche 911

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-E9N4X-012018-01-29. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Optimized software for Porsche Communication Management (PCM) 4.0 has been used in standard production in order to further improve the general performance of the system. These optimizations must be implemented retrospectively even for vehicles manufactured before the date of introduction. Action Required: ? Update PCM software using an SD card ? Re-code the PCM using PIWIS Tester test software version 34.800.030 (or higher
122-Z9T3E-122017-12-14. Service bulletin. LANE DEPARTURE: ASSIST; ELECTRICAL SYSTEM:SOFTWARE. Remedial action In the event of a customer complaint, re-program and code Lane Change Assist control units using 9900 - PIWIS Tester III.
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-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.
122-R7W2C-072017-10-27. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Concerns: AGM starter battery (referred to below simply as ?battery?) Situation: Customer complaints concerning battery-related topics Recurring customer complaints concerning topics relating to battery capacity and quality.
122-B6K8C-112017-10-15. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL; ELECTRICAL SYSTEM. With the introduction of the new Porsche Communication Management system (PCM 4.0), customers of vehicles with a navigation module will be provided with updated maps free of charge for a certain inclusive period as part of the Map Update service. Themaps will be updated for the first time in theMap Update service using an SD card as part of this workshop campaign. In the course of annual model improvements, various functionalities of the PCM have been enhanced, optimizations have been implemented and the general performance of the system has been further improved at the same time. These functional enhancements and optimizations must be implemented retrospectively even for vehicles manufactured before the model improvement measures were introduced. To this end, the PCM software will also be updated using an SD card. Due to the changes to the PCM, the instrument cluster must also be re-programmed using the PIWIS Tester in order to ensure consistency between the displays in PCM and the instrument cluster.
122-Y2D8V-112017-10-15. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. In the course of annual model improvements, various functionalities of the Porsche Communication Management (PCM) system have been enhanced, optimisations have been implemented and the general performance of the system has been further improved at the same time. These function enhancements and optimisations must be implemented retrospectively even for vehicles manufactured before the model improvement measures were introduced. To this end, the PCM software will be updated on the affected vehicles using an SD card. Due to the changes to the PCM, the instrument cluster must also be re-programmed using the PIWIS Tester in order to ensure consistency between the displays in PCM and the instrument cluster.
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.
122-A7B9Q-102017-10-15. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Subject: Oil change service interval in the instrument cluster Information: The instrument cluster on the affected vehiclesmay have been coded with incorrect values for the service interval. As a result, the due date for the oil change service is displayed too late in the instrument cluster. Remedial Action: Re-code service interval
122-H9A7N-092016-11-14. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; ENGINE AND ENGINE COOLING:ENGINE:OTHER FUEL TYPES:TURBO/SUPERCHARGER. "IF THERE IS A LOSS OF POWER OR IF THE FOLLOWING FAULT CODES ARE STORED IN THE FAULT MEMORY, THE WASTEGATE MUST BE CHECKED FOR SMOOTH OPERATION AND CORROSION: • P0133 (OXYGEN SENSOR UPSTREAM OF CATALYTIC CONVERTER, BANK 1) • P0153 (OXYGEN SENSOR UPSTREAM OF CATALYTIC CONVERTER, BANK 2) • P0234 (BOOST PRESSURE CONTROL LIMIT EXCEEDED) • P0299 (BOOST PRESSURE CONTROL DEVIATION) • P2262 (BOOST PRESSURE TOO LOW) CHECK WASTEGATE ON TURBOCHARGER BANK 1 FOR SMOOTH OPERATION AND CORROSION. • CHECK WASTEGATE ON TURBOCHARGER BANK 2 FOR SMOOTH OPERATION AND CORROSION. • IF THE WASTEGATE SHAFT ON TURBOCHARGER BANK 1 IS STUCK, REPLACE TURBOCHARGER ON BANK 1. • IF THE WASTEGATE SHAFT ON TURBOCHARGER BANK 2 IS STUCK, REPLACE TURBOCHARGER ON BANK 2.
122-T8X6Q-092016-10-04. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; ENGINE AND ENGINE COOLING:COOLING SYSTEM.
