Bulletins, newest first
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-M6L9B-062017-08-01. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Concerns: Electronic logbook in Porsche Communication Management (PCM) 3.0 Imformation: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. Implausible entries can appear in the logbook (e.g. negativemileage, double entries) on the affected vehicles due to incorrect PCM software. Earlier entries in the logbook can even be overwritten in some cases.
122-H9M5Z-062017-08-01. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN:CLUTCH ASSEMBLY:PEDAL/HAND LEVER(MOTORCYCLE). Concerns: Clutch pedal switch Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is the possibility that plastic particles may be deposited on the contacts of the clutch pedal switch on the affected vehicles over their service life, causing electric malfunctions of the switch. As a result, the message "Depress clutch pedal" may be displayed in the instrument cluster when you try to start the engine, although the clutch pedal is already pressed, and the engine only starts after several attempts
122-V9B2C-062017-08-01. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Concerns: DME control unit Information: This is to inform you of a voluntary Workshop Campaign on certain 2010 to 2012 model year 911 GT3 (997)/911 GT3 RS (997)/911 GT3 RS 4.0 (997) vehicles. There is the possibility that an implausible oil pressure will be measured and stored in the DME control unit after switching off the engine on the affected vehicles. As a result, this can cause the oil pressure warning light to be activated unnecessarily in the instrument cluster the next time the engine is started. To remedy the situation, re-program the DME control unit using a modified data record.
TI-6-122012-04-04. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; ENGINE AND ENGINE COOLING:ENGINE. PORSCHE: AFTER WITCHING ENGINE OFF, THIS CAUSE OIL PRESSURE WARNING LIGHT TO BE UNNECESSARILY ACTIVATED, IN INSTRUMENT CLUSTER, DUE TO OIL PRESSURE BEING MEASURED AND STORED IN DME CONTROL UNIT. *PE
