The 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).
Check the condition of the rail 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 1032).
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 that there are no external diesel leaks from the high pressure fuel circuit.
Check the continuity and absence of interference resistance of the following connections:
•3LX between components 120 and 1032,
•3LY between components 120 and 1032,
•3LZ between components 120 and 1032.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
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.

Check that the valve is not mechanically jammed (check that the valve is clean and that no component is
preventing it from closing; clean if necessary):
With the engine switched off, disconnect the air inlet hose from the damper valve.
Check that the valve is in the open position.
Start, then switch off the engine.
Check that the valve closes when the engine is switched off and then opens again when the engine has stopped.
If this does not happen, replace the damper valve.
Then run command SC036 Reinitialise programming and select Damper valve to reinitialise the valve's opening

ET007PRE-POSTHEATING UNIT CONTROL
STATUS
DEFINITIONACTIVE: when the heater plugs are activated according to the engine coolant
temperature.
INACTIVE: after the engine has been running for a certain period
In the event of a fault, consult the interpretation of fault DF017 Preheating unit
control circuit.
NOTESSpecial notes:
This status is specific to slow heater plugs (black ring).
Conformity check with engine stopped and ignition on.
"ACTIVE"When the ignition is switched on, status ET007 should be ACTIVE for a time that varies
according to the engine coolant temperature. Both the relay and the heater plugs are
supplied.
After starting, the status should remain ACTIVE for a time that varies according
to the engine temperature. This is the postheating phase.
If ET007 is INACTIVE when the ignition is switched on, check:
– Supply fuse FM12 (70A) of component 597 (engine fuse and relay box) or F2 (70A)
of component 777 for Mégane II and Scénic II
–The supply to the heater plugs after relay actuation, and the connections of the
heater plugs.
Important: on this engine, the plug supply voltage is variable.
– Check the continuity and absence of interference resistance of the following
connections:
•37AB between components 257 and 683,
•37AA between components 257 and 680,
•37Z between components 257 and 681,
•37AC between components 257 and 682.
