Concerns: Control units for rear axle steering Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. Due to a software error in the control units for rear axle steering, there is a possibility that the error message "Fault rear steering Possible to drive on" will be displayed immediately after switching on the ignition.
122-R5K4T-052017-09-14. Service bulletin. POWER TRAIN:AXLE ASSEMBLY. Concerns: Pressure pipe for lift system on front axle Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a possibility that the threaded connections on the pressure pipe for the electropneumatic lift system on the front axle were not tightened to the prescribed tightening torque on the affected vehicles.
122-K7S2R-052017-09-14. Service bulletin. POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE); ELECTRICAL SYSTEM:SOFTWARE. Concerns: Control unit for all-wheel drive system Porsche Traction Management (PTM) Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. The affected vehicles were fitted with a control unit for the all-wheel drive system in which a purging routine for the hydraulic pump drive for the multiplate clutch is not activated due to an error in the control unit software. This can cause wear particles to clog up the hydraulic pump drive over the service life of the vehicle, resulting in higher power consumption for the pump drive. As a result, the all-wheel drive system will be deactivated and the warning message "No all-wheel sys. " Only rear-wh drive" Adapted driving permitted" will be displayed in the instrument cluster.
122-D6U5E-062017-08-01. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION; ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:SOFTWARE. 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-062017-08-01. Service bulletin. POWER TRAIN; POWER TRAIN:AUTOMATIC TRANSMISSION; ELECTRICAL SYSTEM. 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).
