Special notes:
If the fault is present:
– particle filter regeneration is inhibited,
– blue/white smoke and black particles coming from the exhaust,
– the OBD warning light illuminates after three consecutive driving cycles (starting
+ 5 seconds + switch off the ignition and wait 1 minute).
Priorities when dealing with a number of faults:
Firstly, deal with the following faults:
–DF315 Particle filter diff* pressure sensor if it is present or stored.
–DF717 Particle filter upstream pressure if it is present or stored.
Use bornier Elé.1681 for all operations on the engine management computer
connector.
IMPORTANT
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,
Mégane II, Scénic II or Laguna II, component code 1290).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II, Scénic II or Laguna II, component code 120).
If the connector(s) is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, wiring: Precautions for repair), repair the connector(s); otherwise, replace the wiring.
Check the particle filter is present.
