NOTESConditions for applying the fault finding procedure to a stored fault:
If the fault becomes present after:
– the ignition is switched on,
– the engine is started.
Priority when dealing with a number of faults:
Deal with faults DF026 Cylinder 1 injector control circuit, DF027 Cylinder 2
injector control circuit, DF028 Cylinder 3 injector control circuit and DF029
Cylinder 4 injector control circuit first if they are present or stored.
Special notes:
If the fault is present:
–the level 2 injection warning light is illuminated,
– the engine stops.
Use bornier Elé. 1681 for any operations on the connectors of the engine management
computer.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.

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 OBD warning light will illuminate after three consecutive driving cycles (start + 5
seconds, switch off the ignition and wait 40 seconds).
Priorities when dealing with a number of faults:
– DF315 Particle filter diff.* pressure sensor if present or stored
IMPORTANT
In the long term, this fault may lead to premature wear and a greater risk of
turbocharger failure.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
