+ 5 seconds + switch off the ignition and wait 1 minute).
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
Priorities when dealing with a number of faults:
Deal with fault DF013 Sensor supply voltage no. 3 first, if it is present or stored.

If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, run test 4 Checking the turbocharged air inlet circuit and test 5 Air flowmeter,
check that the damper valve is open (valve control resting against the air vent unit),
with the flowmeter connected, the vehicle ignition on and engine stopped,
check the voltage between connections 3DW and 3DV of the air flowmeter:
Replace the air flow sensor if its value is not 0.5 V < X < 0.7 V.
Check the EGR valve is not jammed open:
– Deal with any faults,
– Use the conformity check and Emission control/OBD sub-function,
If these checks show that the valve is jammed or irrevocably seized, replace the EGR valve.
If no faults are revealed, but the fault is still present, replace the air flow sensor.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

STOREDWATER IN DIESEL FUEL DETECTOR CIRCUIT
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Check the conformity and quality of the fuel by running test 11 Diesel fuel conformity check.

A. Check that the water in diesel detection sensor is correctly connected.
– If not, clear the fault,
– carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds.
– If the fault does not reappear, end of fault finding procedure.
– If the fault reappears, go to step C.
b) If the water detection sensor is not present:
–Insulate the electrical connector not connected to the vehicle (risk of humidity, oxidation, and erratic
appearance of faults).
Check that the configuration reading LC065 Water in diesel fuel sensor is WITHOUT.
If LC065 Water in diesel fuel sensor is WITH, run command RZ005 Programming to reinitialise the vehicle
configurations.
– Clear the faults.
– Carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds.
– If the fault does not reappear, end of fault finding procedure.
c) If the sensor is correctly connected:
– Bleed the diesel filter unit (see MR 395 (Laguna II), 370 (Scénic II) or 364 (Mégane II), Mechanical, 13A, Fuel
supply).
– Clear the fault.
– Carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds.
–If the fault does not reappear, end the fault finding procedure.
d)If the fault reappears:
– Check the continuity and absence of interference resistance on connection 3WT between components 414
and 120.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

Check the supply of the water detection sensor between connections 3FB and N.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If none of these checks reveal any faults:
– Replace the water detection sensor (see MR 395 (Laguna II), 370 (Scénic II) or 364 (Mégane II), Mechanical,
13A, Fuel supply).
– Clear the fault.
– Carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds
to confirm the repair.
Note:
If the level of water in the fuel filter unit is lower than the sensor electrodes, certain driving conditions (turns, hills)
may cause erratic illumination of the injection fault warning light.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
