NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the ignition is switched on.
– the engine is started,
– a road test.
Special notes:
If the fault is present:
–the European On Board Diagnostic warning light is lit,
– there is smoke from the exhaust.
Use bornier Ele. 1681 for all operations on the engine management computer
connector.
For EGR valves with a flat connector, it is not possible to check the sensor resistance.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.

Note:
If the computer is new or has just been reprogrammed,
run command SC001 Enter saved data,
only if the save has been carried out on the replacement computer.
(Consult the procedures defined in the Interpretation of commands section).
– After the codes have been written:
– Switch off the ignition and wait for the diagnostic tool message (maximum time 8minutes) Communication
lost with computer: EDC16 C36, check the tool connection and computer power supply before switching
the ignition back on.
– Establish dialogue and clear the fault memory.

Make sure that there is no water in the diesel filter.
Bleed the diesel filter and the low and high pressure diesel circuits, if necessary (see MR 364 (Mégane) or 370
(Scénic), Mechanical, 13A, Fuel supply, and 13B, Diesel injection).
If the diesel filter contains a large amount of water, apply the first part of the Test 11: Diesel fuel conformity check
(Is the fuel cloudy or does it separate into 2 parts?)
Start the engine and wait at least 1 minute to confirm the repair.
If the fault was stored but not present, carry out a road test (see Note).
If the fault does not reappear, end of fault finding procedure.
Check the continuity, insulation and the absence of interference resistance of the following connection:
– Connection code 3WT between components 414 and 120.
Check the +12 V after relay feed of the water detection sensor:
– Connection code3FB of component414.
Check the earth of the water detection sensor:
– Connection code NT of component 414.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
– Start the engine and wait at least 1 minute to confirm the repair.
Check the conformity of the fuel used by running test 11 Diesel fuel conformity check.
If none of these checks reveal any faults:
– Replace the water detection sensor,
– clear the fault,
– start the engine and wait at least 1 minute to confirm the repair.
Note:
When the water level in the fuel filter unit is below the sensor's electrodes, some driving conditions (cornering,
gradients) may result in water being detected (in fact, the sensor's off-centre position in the fuel filter unit, combined
with the driving conditions, causes water to be detected).
