Engine starts.
Check that the oil level is correct and that the
engine coolant temperature is greater than 60°C.
Engine running at idle speed.
– Run command AC029 High pressure circuit
sealing test.
The engine will perform 4acceleration cycles
– Refer to parameters PR008 Rail pressure
setpoint and PR038 Rail pressure.
–Does PR038 Rail pressure follow PR008 Rail
pressure setpoint at +
50 bar during the
phase of the 4 acceleration cycles?
Note:
If the rail pressure does not reach the setpoint
there is an injector leak that is too great or the
pressure signal is incorrect.
NO
Test 5
YES
High-pressure
pump and fuel flow
solenoid valve OK.
The engine does not start.
Check that the oil level is correct.
– With the starter activated (3 seconds) consult
parameters PR008 Rail reference pressure
and PR038 Rail pressure.
–Does PR038 Rail pressure follow PR008 Rail
pressure setpoint when the starter is run?
NO
Test 6
YES
Contact the
Techline.
Note:
If the rail reference pressure is not achieved
during starting, there is an injector leak that is
too great or the pressure signal is incorrect.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

Reconnect the fuel flow solenoid valve
connector; before restarting the engine, switch
off the ignition and wait 30 seconds.
Remove the connector for the fuel pressure
solenoid valve (white), does the engine stop?
YES
Reconnect the connector of the fuel pressure
solenoid valve, switch off the ignition and wait for
30 seconds.
Check that the oil level is correct and that the
engine coolant temperature is greater than 60°C.
Engine running at idle speed.
– Run command AC029 High pressure circuit

– Refer to parameters PR008 Rail pressure
setpoint and PR038 Rail pressure.
–Does PR038 Rail pressure follow PR008 Rail
pressure setpoint during the phase of the
4acceleration cycles?
NO
NOReplace the pump (the fuel pressure
solenoid valve remains closed
mechanically).
YESCheck the injectors by carrying out Te s t 6.

Weigh the diesel fuel and note the fuel weight after subtracting the weight of the empty plastic cup and its cover.
Does the fuel weight fall between the minimum and maximum weights given in the table below?

Check the fuel temperature by immersing a thermometer in the plastic cup.
End of test.The fuel is not correct.
If the fuel weight is less than the minimum value then there is
petrol in the diesel fuel.
If the fuel weight is greater than the maximum value then there is
oil in the diesel fuel.
Drain the fuel circuit, including the tank (see MR 392 (Clio III),
364 (Mégane II ph2), and 417 (Kangoo II), Mechanical, 19C,
Tank, Fuel tank: Draining or MR 385 (Modus) and 370 (Scénic II
