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
Diagnosis Information - PDK (Dual-Clutch Transmission)
P0843
Diagnostic information - PDK
Pressure sensor 1, 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.
- Engine running
- The following fault is not stored: P1706
- The following fault is not stored: P1707
Possible fault causes
- Line between pressure sensor 1 and PDK control unit faulty
- Pressure sensor 1 faulty
- PDK control unit faulty
- Clutch 1, measured oil pressure > 21 bar
Fault setting conditions
- Pressure sensor 1, signal > 4.5 V
Fault effects
- Engaged gear is held until vehicle stops
- Moving off possible only in 2nd gear
- Only gears 2, 4 and 6 are possible
