Vehicle Type: 911 Carrera (997)/911 Carrera S (997)
911 Carrera 4 (997)/911 Carrera 4S (997)
Equipment:
Porsche Doppelkupplung (PDK) - I-no. 250
Concerns:
PDK transmission/control unit for PDK transmission
Situation:
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
Information
^ Always create a Vehicle Analysis Log (VAL) before starting any measures.
^ Make sure that you are using the latest version of the PIWIS Tester I 9718 software (i.e. version 27.000 or higher)/PIWIS Tester II software version 5.200 or higher.
^ If components are replaced: Return components to Porsche and document all measures in PPN.
Information
The following procedure applies in relation to calibration:
Engine torque loss adaptation must always be performed before carrying out calibration (for details of procedure/conditions, see Step 3.6).
Essentially, calibration is required only after replacing parts or if you are expressly instructed to do so during troubleshooting.
A Calibration after part replacement routine ("major calibration routine") must always be carried out after replacing one of the following components:
- PDK control unit
- Electrohydraulic control unit
- PDK transmission
Calibration without previous part replacement ("minor calibration routine") must be carried out if you are expressly instructed to do so (e.g. during troubleshooting in the event of complaints relating to comfort).
When control unit programming is complete (DME/PDK - with or without part replacement), engine torque loss adaptation must be performed.
If a control unit was only re-programmed (without replacing parts), calibration is not required unless there are other faults present (e.g. problems relating to gearshift and drive-off quality) for which calibration is recommended in order to correct the faults.
