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).

Test the high pressure fuel circuit:
Apply scenario SC035 High pressure fuel circuit fault finding.
To interpret the result, apply the interpretation of command SC035 (see Interpretation of commands).
With the engine stopped and ignition on, view parameters PR035 Atmospheric pressure and PR041
Turbocharging pressure.
If there is a difference of > 100 mbar, check that the atmospheric pressure reading is consistent (by comparison
with another vehicle for example).
If atmospheric pressure is consistent, replace the turbocharging sensor.
If not, contact the Techline.
Use the Monitool application: MT001 Turbocharging function to check the entire air line (only for Vdiag 04 and
44).
Apply Test 4 Turbocharged air inlet circuit check.
Run Test 7 Variable geometry turbocharger control.
Run Test 8 Turbocharger rotating part.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the ignition is switched on,
– with the engine running,
– road test.
Priorities when dealing with a number of faults:
– DF898 Pressure regulator circuit on rail,
– DF897 Pressure regulator circuit on pump,
– DF896 Pressure regulation on pump.
Special notes:
DF895 depends on the pressure regulator built into the rail (DRV).
DF896 Pressure regulation on pump depends on the pressure regulator integrated
in the pump (MPROP).
The fuel pressure regulator built into the rail (DRV) and the fuel pressure regulator built
into the pump (MPROP) are never actuated at the same time.
If the fault is present:
– particle filter regeneration is inhibited,
– the engine stops and the level 2 warning light comes on: 1.DEF, 4.DEF,
–the level 1 warning light comes on: 2.DEF, 3.DEF, 4.DEF,
– engine torque limited 2.DEF, 3.DEF, 4.DEF,
– the rail pressure is regulated by a regulator built into the pump (MPROP): 2.DEF,
3.DEF, 4.DEF.
Use bornier Elé.1681 for all operations on the engine management computer.

Check that there are no leaks on the high pressure diesel fuel circuit.
Repair if necessary.
Check the level of fuel in the tank.
In the event of a fuel gauge sensor fault, deal with this fault first.
Check the low pressure circuit using Test 3 Low pressure circuit test and check that there are no exterior air
leaks in the low pressure fuel circuit.
Test the high pressure fuel circuit:
Run scenario SC035 High pressure fuel circuit fault finding (see Interpretation of commands).
If the fault is still present, check the rail pressure regulator connections (DRV).
check the engine management computer connections.
Check the seal on the rail pressure regulator (DRV):
Disconnect the low-pressure return pipe from the rail pressure regulator (DRV). In its place, connect a transparent
pipe, with the other end leading to a container of some sort in order to collect the drained diesel fuel.
Start the engine and let the engine idle.
When the engine is started, no diesel should flow into the transparent pipe as the rail pressure regulator (DRV) is
closed so that the pressure in the hydraulic system can rise.
Diesel fuel should flow into the transparent pipe a few seconds after the engine is started, provided that the diesel
is cold (less than 15°C), as the regulation is provided by the rail pressure regulator (DRV).
If the diesel is warm (above 15°C), regulation is controlled by the pump pressure regulator (MPROP). No diesel
should flow into the pipe.
