NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
–the level 1 warning light is lit,
– the EOBD (European On Board Diagnostic) warning light will come on after three
consecutive driving cycles (starting + 5 seconds + switching off the ignition and
waiting for 1 minute),
– the particle filter fault finding procedure is inhibited,
– particle filter regeneration is inhibited.
Check the condition of the pressure pipe between the particle filter upstream take-off point and the differential
pressure sensor.
Check that the pipe is not crushed, blocked or pierced.
Check that the differential pressure sensor is correctly positioned and connected (see MR 395, 402, 405, 364, 370,
Mechanical, 19B Exhaust, Particle filter pressure sensor: Removal - Refitting).
Replace the pressure pipe if necessary.

1.DEF: Above max threshold
NOTESConditions for applying fault finding procedures to stored faults:
The fault becomes present during an After-Sales regeneration carried out using the
diagnostic tool at a speed above zero.
Special notes:
If the fault is present, the particle filter regeneration in progress is interrupted.
IMPORTANT:
The fault is present because the vehicle was driven while the After-Sales regeneration was in progress.
The vehicle must remain stationary throughout regeneration.
DO NOT DRIVE THE VEHICLE.
CHECK THAT THE VEHICLE IS CORRECTLY IMMOBILISED.
– Switch off the ignition and wait for the diagnostic tool message (maximum wait 8 minutes): Loss of dialogue
with the computer: EDC16 CP33, check the tool connection and the computer supply,
– switch on the ignition again,
– establish dialogue with the injection computer, clear the faults from the computer memory,
– carry out another After-Sales regeneration,
– run command SC017 Particle filter regeneration and follow the procedure described in Interpretation of
commands.
If the fault is still present, contact the Techline.

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.
