2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 467
Fault setting condition(s)
- Power supply Control unit DME (DFI) > 4.0 V to connector [A] contact 3/5/6, at:
- Power supply Control unit DME (DFI) 0.0 V to connector [A] contact 34 (Terminal 15)
INFORMATION
- After the ignition is switched off (terminal 15), the DME control unit switches to control unit after-run mode.
- The run-on period depends on many boundary conditions (e.g. engine temperature for fan operation).
The run-on duration can be 1 minute when the engine is cold and up to 45 minutes when the engine is hot.

Main relay ON
Diagnostic conditions
- Vehicle voltage > 8.0 V
- Ignition on
Possible fault causes
- Main relay Faulty
- Open circuit Power supply Control circuit Main relay
- Short circuit to ground or open circuit in lines between Main relay and Control unit DME (DFI) (Power supply Control unit DME (DFI))
- Short circuit to B+ or open circuit in lines between Control unit DME (DFI) and Main relay (Activation Main relay relay)
Fault setting condition(s)
- Power supply Control unit DME (DFI) < 6.0 V to connector [A] contact 3/5/6, at:
- Power supply Control unit DME (DFI) > 8.0 V to connector [A] contact 34 (Terminal 15)

P0700
Diagnosis information - Control unit DME (DFI)
Transmission Control System Malfunction
Diagnostic conditions
- Engine running
Possible fault causes
- Fault entry in the PDK control unit (See [Information])
INFORMATION
Different fault healing strategies in the engine and transmission control units can lead to the situation in which the original transmission fault no
longer exists in the transmission fault memory (healed) but the note (P0700) nevertheless remains entered in the engine control unit (not yet healed).
Selector Lever Position Implausible
P0702
Diagnosis information - PDK
Selector lever position implausible
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
Possible fault causes
- PDK control unit faulty
- Selector lever control unit faulty
- Serial line between PDK control unit and selector lever faulty
Fault setting conditions
- Signal from CAN does not match serial data signal
