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).
