PRESENT OR
STOREDPRESENCE OF WATER IN THE DIESEL FUEL
NOTESPriorities when dealing with a number of faults:
–DF057 Water in diesel fuel detector circuit,
Special notes:
If water is detected downstream of the diesel filter, the high pressure pump and
the injectors may be damaged.
The level 1 warning light is illuminated.
Use bornier Elé. 1681 for all operations on the engine management computer
connector.
See the Technical Note Wiring Diagrams for the vehicle.
If there is water present, bleed the diesel filter.
If there is a great amount of water, run the first part of Test 13: Diesel fuel conformity check (Is the fuel cloudy
or does it separate into 2 parts?)
Check the connections of the water in diesel fuel sensor, component code 414.
Check the connections of the engine management computer grey connector, component code 120.
If the connector(s) are faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector(s), otherwise replace the wiring.
With the ignition on, check for +12 V on connections 3FB1 or 3FB2 (for New Twingo) or AP15 (for Kangoo 2) of
component 414.
Check for earth on connections M or 3WU (only for New Twingo) of component 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 the wiring.

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 the wiring.
If the fault is still present, replace the diesel filter.
If the fault is still present, contact the Techline

Test the air inlet circuit (from the air filter inlet to the inlet manifold tracts, run test 5 Inlet circuit check):
–air filter unit inlet not blocked and filter not clogged,
–oil vapour recirculation circuit connected correctly,
–low and high pressure air circuit sealed and not obstructed: ducts, mounting clamps present and tightened,
turbocharging pressure sensor fitted, exchanger, etc., run TEST 1 Low pressure circuit check and TEST 7
High pressure circuit sealing check
–check that the damper valve is not jammed closed.
Carry out the necessary repairs.
Check the electrical conformity of the air flowmeter:
Check the + 5 V supply of the air flowmeter on the following connection:
–3KJ of component 799.
Check the + 12 V after relay supply of the air flowmeter on the following connection:
–3FB (or 3FB3) of component 799.
Check the continuity and absence of interference resistance of the following connections:
–3DV,
–3DW, between components 120 and 799.
Flowmeter connected, vehicle ignition on and engine stopped:
Measure the voltage between connections 3DW and 3DV of component 799.
If the voltage is not between 0.3 V and 0.7 V, replace the air flowmeter, component code 799 (see MR 364 (Mégane
II), MR 370 (Scénic II), MR 385 (Modus), MR 392 (Clio III), MR 411 (New Twingo), MR 417 (Kangoo 2),

TEST 1 Low pressure circuit check
Check the conformity of the low pressure circuit
connections.
Are the low pressure circuit connections correct? Carry out the necessary repairs.
Check the condition of the priming bulb, and that it is
working properly.
Look for leaks at the unions.
Are there leaks from the hoses and unions? Carry out the necessary repairs.
Check that there are no air bubbles in the diesel fuel.–Bleed the low-pressure circuit.
–Place a container under the filter.
–Disconnect the return hose from the filter
and plug the filter.
