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 and absence of interference resistance of the following connections:
•3KX between components 120 and 194,

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).

Special notes:
If the fault is present:
– particle filter regeneration is inhibited,
– blue/white smoke and black particles coming from the exhaust,
– the EOBD (European On Board Diagnostic) warning light will come on after three
consecutive driving cycles (starting + 5 seconds + switch off the ignition and wait
40 seconds).
–The level 1 warning light is lit (for Vdiag 20, 24, 58, 5C, 26, 28, 60 and 62).
Priorities when dealing with a number of faults:
– DF315 Particle filter diff. pressure sensor if present or stored.
– DF717 Particle filter upstream pressure if it is present or stored.
NOTE:
In the long term, this fault may lead to premature wear and a greater risk of turbocharger
failure.
Check the condition of the differential 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 1290).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
