Setpoint definitions
NOTE: The specified values and value ranges correspond to the OK state in each case.
Line test setpoints
Short circuit to B+:
- Setpoint voltage -0.5 V --> +0.5 V
Short circuit to ground:
- Setpoint resistance > 0.9 MOhm
Open circuit:
- Setpoint resistance < 2 Ohm
Setpoints for P/R actuator solenoid activation
- Activation signal > 9 V --> < 16 V
Setpoints for P/R actuator solenoid
- Internal resistance > 20 Ohm --> < 25 Ohm
Diagnosis Information - PDK (Dual-Clutch Transmission)
P0931
Diagnostic information - PDK
Actuator solenoid R/P interlock, short circuit to ground
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.
- The following fault is not stored: P1833
- The following fault is not stored: P183B
Possible fault causes
- Line between selector lever control unit and PDK control unit faulty
- Actuator solenoid for R/P interlock faulty
- PDK control unit faulty
Fault effects
- Transmission limp-home indication in instrument cluster control unit
With P17A1
P0960
Diagnosis information - PDK
Pressure regulator 1 (clutch 1), shunt
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: P0960
- The following fault is not detected: P0962
- The following fault is not detected: P0963
Possible fault causes
- Shunt circuit in line between pressure regulator 1 and PDK control unit
- Pressure regulator 1 faulty
- PDK control unit faulty
