NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
–the level 1 warning light is lit,
– the EOBD (European On Board Diagnostic) warning light will come on after three
consecutive driving cycles (starting + 5 seconds + switching off the ignition and
waiting for 1 minute),
– the particle filter fault finding procedure is inhibited,
– particle filter regeneration is inhibited.
Priorities when dealing with a number of faults:
–DF315 if it is present.
–DF308 Particle filter clogged if DF315 is stored and DF308 is present.
–DF011 Sensor supply voltage no. 1 if it is present or stored.
CC.1
NOTESNone.
Check the condition of the differential pressure sensor connector (see Wiring Diagram Technical Note, Laguna

Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
