Some repair operations require programming to ensure that certain engine components function correctly.
Follow the programming procedures (see Replacement of components), if replacing the exhaust gas
recirculation valve or an injector.

3. Conditions for deleting an OBD fault
An OBD fault is deleted in several phases.
The fault present on the diagnostic tool will only become stored (after a repair operation) after the vehicle has
been driven 3 times.
The OBD warning light will only go out after these 3 trips.
The instrument panel warning light coming on does not automatically mean that the system has a fault.
In order for the OBD fault and display parameters to be cleared from the computer, the system requires
40 engine heating cycles.
An engine heating cycle is a driving cycle during which:
– the engine coolant temperature reaches at least 71.1°C,
– the engine coolant temperature varies by 22.2°C in relation to the engine starting temperature.
If one of these conditions is not fulfilled, the OBD fault will still be present or stored on the injection
computer.

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.

1. DEF: Above maximum threshold
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the engine is started.
– a road test.
Special notes:
If the fault is present:
– particle filter regeneration is inhibited.
Use bornier Elé. 1681 for any operations on the injection computer connectors.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Note:
This fault is activated in case of considerable oil dilution due to a significant number of particle filter regenerations.
Carry out the following:
– An oil change (see MR 364 (Mégane II) or MR 370 (Scénic II), Mechanical, 10A Engine and peripherals,
Engine oil: Draining – Filling),
– reset the oil wear meter,
– clear the faults.
Reset the oil wear meter after the oil change:
It will be necessary to reinitialise the display of the trip computer.
With the ignition on:
– hold down the TC* button for 5 s.
Re-initialisation has worked when the on-board computer no longer displays the key.
If this is not the case, restart the procedure.
Specific case:
If an oil change is performed before the oil service interval warning is exceeded, reinitialise the display.
