Model year: as of 2010
Information
This bulletin replaces bulletin Group 3, #43/10, dated April 6, 2011.
Changes/additions compared to the previous Technical Information:
New PDK Diagnostic Flow Charts dated 8/2011.
Vehicle Type: Panamera/Panamera S/Panamera 4/Panamera 4S/Panamera Turbo
Equipment: Porsche Doppelkupplung (PDK) - I-no. 250
Concerns:
PDK transmission/control unit for PDK transmission
Information:
Procedure and repair measures in the event of complaints relating to PDK:
^ Gearbox emergency operation/other warning messages
^ Fault memory entries in the fault memory of the PDK control unit
^ Leaks on the PDK transmission
^ Complaints relating to comfort
^ Complaints relating to noises
This Technical Information is divided into the following sections:
^ Procedure and repair measures in the event of fault entries in the fault memory of the PDK control unit
^ Repair measures in the event of leaks on the PDK transmission
^ Remedial action and repair measures in the event of complaints relating to comfort and noise
Information
^ Always create a Vehicle Analysis Log (VAL) before starting any measures --> 0X03IN Creating Vehicle Analysis Log (VAL).
^ When evaluating faults, also bear in mind the detailed information contained or stored in the relevant fault code (measured values, etc.).
^ Make sure the version of the PIWIS Tester II 9818 software you are using is the latest version.
^ If components are replaced: Return components to the Porsche and document all measures in PIWIS/PQIS.

Information on PDK calibration and engine torque loss adaptation
Engine torque loss adaptation
Engine torque loss adaptation must always be performed before calibrating PDK. Engine torque loss adaptation is also required after carrying out control unit programming (DME/PDK - with or without part replacement).
Conditions/procedure for engine torque loss adaptation:
^ Engine temperature is at least 176°F. (80°C.) (read out the temperature from the PDK control unit by selecting "Actual values/Input signals" > "CAN input signals - Engine temperature").
^ All loads switched off.
^ PDK selector lever in position P.
^ Allow engine to run at idle speed for 3 minutes with air conditioning switched off.
^ Then allow engine to run at idle speed for 3 minutes with air conditioning switched on.
^ Switch off ignition and wait 15 seconds (adaptation values are stored).
PDK calibration
Essentially, PDK calibration is required only after replacing parts (of the PDK control unit, hydraulic switch unit, PDK transmission) or if you are expressly instructed to do so during troubleshooting.
PDK calibration can be started by selecting the PDK control unit under > "Maintenance/repairs" >> "Calibration (complete process)" using PIWIS Tester II. Shift travel, hydraulics and clutches are calibrated during calibration. It is not possible to perform a "minor" calibration routine ("Calibration without previous part replacement") -which you may be familiar with from the Boxster, Cayman and Carrera sports cars - on the Panamera.
Engine torque loss adaptation must always be performed before carrying out calibration.
The preconditions for engine torque loss adaptation and PDK calibration are summarized again in the overview above.
