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.
