NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the ignition is switched on,
– a road test.
Special notes:
Use the bornier Elé. 1681 for all operations on the connectors of the injection
computer.
The richness ratio sensor is only present on certain F9Q818 engines. Check that the
vehicle is correctly equipped with this sensor.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Check the condition of the connector of the richness ratio sensor (see Wiring Diagram Technical Note, Mégane
II ph2, Scénic II ph2, Component code 1587).
Check the condition of the connector of the engine management computer (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 the continuity, insulation and absence of interference resistance on the following connections:
– Connection code 3AAS between components 1587 and 120.
– Connection code 3AAT between components 1587 and 120.
– Connection code 3AAU between components 1587 and 120.
– Connection code 3AAV between components 1587 and 120.
– Connection code 3AAW between components 1587 and 120.
Check for + 12 V on the connector of the richness ratio sensor.
– Connection code 3FB of component 1587.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.

STOREDENGINE OIL DILUTION
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.
