Setpoint Definitions
P2815
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
NOTE: The specified values apply only at an ambient temperature of approx. 20 锟斤拷C (68 锟斤拷F) (room temperature).
Pressure regulator setpoints
- Internal resistance > 3.7 --> < 6.4 Ohm
Diagnosis Information - PDK (Dual-Clutch Transmission)
P2815
Diagnostic information - PDK
Pressure regulator 7 (hang-on clutch), short circuit to B+
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
- The following fault is not detected: P1842
Possible fault causes
- Line between pressure regulator 7 and PDK control unit, short circuit to B+
- Pressure regulator 7 faulty
- PDK control unit faulty
Fault setting conditions
- Internal current measurement, pressure regulator 7: current consumption > 850 mA
Fault effects
- Pressure regulator 7 switch-off
- Engaged gear is held until vehicle stops
- Transmission limp-home indication in instrument cluster control unit
P3052
P3052
Diagnosis information - Control unit DME (DFI)
Activation Starter relay
Diagnostic conditions
- only PDK: Brake actuated + Selector-lever position P or N
- only Manual transmission: Clutch complete depress
- Ignition on > 3 Second(s)
