2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 17
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
- The following fault is not detected: P1842
Possible fault causes
- Shunt circuit in line between pressure regulator 5 and PDK control unit
- Pressure regulator 5 faulty
- PDK control unit faulty
Fault setting conditions
- Actual pressure regulator current < setpoint current (maximum deviation = 35 mA)
Fault effects
- Power supply switch-off, pressure regulator for system pressure and synchro selection
- Power supply switch-off, solenoid valves
- Pressure regulator for system pressure and synchro selection, switch-off
- Solenoid valves switch-off
- Last gear held
- Transmission limp-home indication in instrument cluster control unit
With P17A5
P17AD
Diagnosis information - PDK
Electrical pressure adjuster 5, shunt
