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.

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).

Check the status of the connector of the rail pressure sensor (see Wiring Diagram Technical Note, Mégane II
ph2, Scénic II ph2, Component code 1032).
Check the status of the connector of the rail pressure sensor (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 and absence of interference resistance on the following connections:
– Connection code 3LX,
– Connection code 3LY,
– Connection code 3LZ,
between components 120 and 1032.
If any of the connections are faulty and there is a repair method (see Technical Note 6015A, Electrical wiring
repair, Wiring: precautions for repairs), repair the wiring; otherwise replace the wiring.
Check that there is no external diesel leak from the high pressure fuel circuit.
With the ignition on and the engine stopped for over 1 minute:
Display parameter PR038.
– If the pressure is below 90 bar, the sensor is in order.
– If the pressure is above 90 bar, contact the Techline.

PARAMETER
DEFINITIONThis parameter indicates the fuel temperature in °C.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
There must be no present or stored faults.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– after a customer complaint (e.g. lack of power).
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
This parameter indicates the fuel temperature: - 30°C < PR063 < 90°C
Default value: 100°C
In the event of a fault, see the interpretation of DF098 Fuel temperature sensor circuit.
