Concerns: Porsche Communication Management \(PCM\) 3.1 Information: This is to inform you of a voluntary Workshop Campaign on the above\-mentioned vehicles. In the event of faulty transmission of XMdata by the satellite radio operator, there is a possibility that significantly more data than usual will be sent at times. As a result, the amount of data sent can no longer be processed by PCM and cyclical restarts of the PCM system can then occur continuously.

Concerns: Electronic logbook in Porsche Communication Management \(PCM\) 3.1 Information: 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\-Z5F9U\-06](/bulletins/10109303.md), 2017-08-01, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); POWER TRAIN; ELECTRICAL SYSTEM:SOFTWARE. Concerns: PDK control unit Information: This is to inform you of a voluntary Workshop Campaign on certain 911 Carrera \(991\) and 911 Carrera S \(991\) vehicles. The PDK control unit can sometimes be misdiagnosed on the affected vehicles due to a software error if the engine is switched off in selector\-lever positions "P" or "D" and is then re\-started again in selector\-lever position "N". As a result, fault code "P1772 \- Gear valve 2 stuck on pressure" is stored in the fault memory of the PDK control unit and the PDK transmission switches to the reduced driving program until the ignition is switched off and on again.

Concerns: PDK control unit Information: This is to inform you of a voluntary Workshop Campaign on the above\-mentioned vehicles. A shift rod movement at a shift gate that was not selected can be detected incorrectly on the affected vehicles due to a software error. As a result, fault code "P1767 \- Hydraulic multiplexer fault" can be stored in the fault memory of the PDK control unit and the PDK transmission can switch to the reduced driving programme until the ignition is switched off and on again.
