Service bulletin TI-85-13

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-R2J7H-06	2017-08-01. Service bulletin. 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-D6U5E-06	2017-08-01. Service bulletin. 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.
122-G7E5R-06	2017-08-01. Service bulletin. Concerns: PDK transmission Information: There is a possibility of moisture condensing in the vent line of the PDK transmission under certain environmental influences and getting into the inside of the PDK transmission through the ventilation connections. The transmission oil/water emulsion created as a result of this is deposited on the inner contacts of the multiple plug connection for the PDK transmission and causes electric shunt circuits there. If this happens, the PDK transmission can malfunction, e.g. switch to the reduced driving program (limp-home mode).
