NOTESPriority when dealing with a number of faults:
If DF012 Sensor feed voltage no. 2 is present or stored:
– deal with it first,
– fan assembly GMV1 activated (low-speed),
– heating and air conditioning system inhibited.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Check the condition of the refrigerant pressure sensor connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, component code 1202) and ensure that it is operating correctly.
Check the condition of the engine management computer connector (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 insulation, continuity and the absence of interference resistance on the following connections:
– connection codes 38U, 38X, 38Y between components 1202 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the wiring of the particle filter downstream temperature sensor, component code 1288, is present (with or without
the sensor being present), check the electrical insulation in relation to + 12 V between the following connections:
•3XU between components 120 and 1288,
•3TG between components 120 and 1288.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.

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).

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– particle filter regeneration is inhibited,
– the EGR function is inhibited,
– the vehicle performance is reduced,
–the level 1 warning light is lit and a warning message (or light) is displayed on the
instrument panel.
Priorities when dealing with a number of faults:
Deal with the following faults first:
– DF315 Particle filter differential pressure sensor if it is present.
– DF308 if DF315 is stored.
– DF316 Particle filter diff* pressure sensor if it is present or stored.
– DF226 Damper valve circuit if it is present or stored.
– DF272 EGR valve control circuit if it is present or stored.
– DF647 EGR valve position regulation if it is present or stored.
– DF309 Particle filter downstream temperature sensor if it is present or stored.
– DF899 Regeneration temperature threshold exceeded if it is present or stored.
– DF310 Particle filter upstream temperature sensor if it is present or stored.
– DF778 Turbine upstream temperature regulation if it is present or stored.
– DF652 Turbine upstream temperature sensor circuit if it is present or stored.
