| 122-B9V4V-06 | 2018-06-25. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Information: The Approval and Support Management system was created to offer assistance to the dealer organization with new and complex technical issues by utilizing the Support Specialists within Porsche R&D. As a result, this process has reduced vehicle downtime and repeat repairs substantially. |
| 122-T7Y5Q-12 | 2017-12-14. 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-E3L8H-03 | 2017-10-25. Service bulletin. VISIBILITY:SUN/MOON ROOF ASSEMBLY. Cause: Noises can be caused by excessive relative movements between the individual components. Remedial Action: Rework sliding roof seal. |

| 122-M6L9B-06 | 2017-08-01. 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-V3U7E-06 | 2017-08-01. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV); ENGINE AND ENGINE COOLING. Concerns: Plug on crankcase for cylinders 1-3. Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is the possibility that a plug that was pressed into and sealed to the crankcase is not seated securely enough in the opening on the affected vehicles. As a result, this can cause the plug to become loose and as a result, oil can suddenly leak out of the crankcase, resulting in immediate engine damage. |
| 122-H9M5Z-06 | 2017-08-01. 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-Y7J8H-06 | 2017-08-01. Service bulletin. VISIBILITY:SUN/MOON ROOF ASSEMBLY; EQUIPMENT:MECHANICAL. Concerns: Tension rope for the convertible top rooflining Information: This is to inform you of a voluntary Workshop Campaign on certain 2011 911 Speedster (997) vehicles. There is the possibility that the tension rope for the convertible top rooflining may get caught on the linkage when operating the convertible top. As a result, this may cause the tension rope to break and the convertible top rooflining in the rear area will not be tensioned when the convertible top is closed. |
| 122-V9B2C-06 | 2017-08-01. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL.

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. |
| 122-D5B3L-06 | 2017-07-28. Service bulletin. ENGINE. Center intake-air distributor Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. An intake-air distributor, on which the shaft for guiding the resonance flap does notmeet the required specifications, may have been installed on the affected vehicles. As a result, the shaftmay break and broken pieces may get into the intake duct and end up in the combustion chambers. This can cause loud noises. It can also result in mechanical damage if the engine is not stopped in time. |
| 122-W9N9W-06 | 2017-07-28. Service bulletin. POWER TRAIN; POWER TRAIN:MANUAL TRANSMISSION.
