2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 748
Diagnostic conditions
The control unit initially tests internal function sequences when the ignition is switched on (terminal 15). If they are OK, all diagnosable outputs are
then tested and any faults are stored.
- Ignition on
- The following fault is not detected: P1832
- The following fault is not detected: P183A
Possible fault causes
- Line between pressure regulator 5 and PDK control unit, short circuit to ground
- Pressure regulator 5 faulty
- PDK control unit faulty
Fault setting conditions
- Internal current measurement, actuator solenoid R/P: current consumption = 0 mA
- Pressure regulator 5, internally measured control current = 0 mA
- Pressure regulator 5, measured voltage = 0 V
Fault effects
- Power supply switch-off for pressure regulators 4 to 6
- Power supply switch-off for solenoid valves 1 and 2
- Pressure regulator 4 switch-off
- Pressure regulator 5 switch-off
- Pressure regulator 6 switch-off
- Solenoid valve 1 switch-off
- Solenoid valve 2 switch-off
- Engaged gear is held until vehicle stops.
- Moving off possible in all gears
- Transmission limp-home indication in instrument cluster control unit
Diagnosis Information - PDK (Dual-Clutch Transmission)
P2730
