2.DEFNOTESThe fault is declared present or stored after an attempt to
start or after starting, with the engine cold, several hours
after the last trip (the difference in the coolant temperature
from the last engine stop and the present attempt to start
must be at least 60°C).
The level 1 warning light is on.
Check the condition of the rail pressure sensor connector (see Wiring Diagram Technical Note, Mégane II ph2,
Scénic II ph2, component code 1032).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
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 that there are no external diesel leaks from the high pressure fuel circuit.
Check the continuity and for the absence of interference resistance on the following connections:
– connection code 3LZ between components 120 and 1032,
– connection code 3LX between components 120 and 1032,
– connection code 3LY between components 120 and 1032.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
With the ignition on and the engine stopped for over 1 minute:
View parameter PR038 Rail pressure.
– If the pressure is below 90 bar, the sensor is in order.
– If the pressure is above 90 bar, contact the Techline.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

DF065 appears on the diagnostic tool when the engine management computer has detected a fault during the
combustion phase several times in succession.
Several components may be responsible:
– the piston rings,
– the piston,
– the valves,
– the injector,
– the heater plug sealing.
Check that the stored injector codes are consistent with those engraved on each injector. If not, run command
SC002 Enter injector codes, and follow the procedure.
When dealing with a number of misfiring faults, check the fuel conformity by running test 11 Diesel fuel
conformity check.
Check the engine compressions.
Carry out the necessary repairs.
If the fault is still present, apply test 10: Incorrect injector operation.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.
