NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present with the engine running.
Special note:
If fault DF218 is present, the engine stops, restarting is impossible and the level 2
warning light comes on.
Enter the individual injector corrections (C2I) using the diagnostic tool (command SC002 Enter injector codes).
If the fault is still present, contact the Techline.

STOREDPRESENCE OF WATER IN THE DIESEL FUEL
1.DEF: Open circuit on the line or presence of water in the diesel fuel
NOTESFault finding procedure application conditions:
The fault is declared present after the engine has been started.
Priorities when dealing with a number of faults:
– DF057 Water in diesel fuel detector circuit,
Special note:
If the fault is present, the level 1 warning light comes on or the water present in
diesel fuel warning light comes on (if present on the instrument panel and if
configured in injection).
Use the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2 or Kangoo VLL.
Check for the presence of water in the diesel filter; if water is 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 connection and condition of the connector of the water in diesel fuel sensor, component code 414.
Check the connection and condition of the injection computer connector, component code 120.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or Technical
Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the connector, otherwise
replace the wiring.
Check for a voltage between 13V and 14V (with the engine running) and between 11.5 V and 12.5 V (with the
ignition on and engine stopped) on connection 3FB (or 3FB2, or 3FBA) on the connector of the water in diesel
fuel sensor, component code 414.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or Technical
Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise
replace it.
