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:
– particle filter regeneration is inhibited,
– blue/white smoke and black particles coming from the exhaust,
– the EOBD (European On Board Diagnostic) warning light will come on after three
consecutive driving cycles (starting + 5 seconds + switch off the ignition and wait
40 seconds).
–The level 1 warning light is lit (for Vdiag 20, 24, 58, 5C, 26, 28, 60 and 62).
Priorities when dealing with a number of faults:
– DF315 Particle filter diff. pressure sensor if present or stored.
– DF717 Particle filter upstream pressure if it is present or stored.
NOTE:
In the long term, this fault may lead to premature wear and a greater risk of turbocharger
failure.
Check the condition of the differential pressure sensor connector (see Wiring Diagram Technical Note, Laguna
II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 1290).
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.

Check the particle filter is present.
If it is present:
Visually check that the particle filter is in good condition by positioning the vehicle on a lift:
– not damaged (no abnormal welds, if necessary compare it with another vehicle fitted with particle filter),
– if there are After-Sales sleeves, as a result of a previous operation, check that the particle filter's contents were
not emptied out when it was removed.
If the particle filter is not working correctly or is absent:
– replace it,
– run command SC036 Reinitialise programming and select After particle filter replacement (see
Interpretation of commands),
– switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Loss of dialogue
with the computer: EDC16 CP33, check the tool connection and the computer supply voltage,
– then switch on the ignition again,
– clear the faults from the computer memory (this operation must be carried out within 3 minutes of the ignition
being switched on).
If the fault is still present, contact the Techline.
