If the filter is present,
Visually inspect the particle filter by placing the vehicle on a lift:
– not damaged (no abnormal welds, if necessary compare it with another vehicle fitted with particle filter),
– if After-Sales sleeves are present, due to work being carried out previously, check that the particle filter's
contents were not emptied out when it was removed.
If the particle filter is not working correctly or is absent:
– Replacing the particle filter,
– run command SC036 Reinitialise programming and select After particle filter replacement (see
Interpretation of commands).
– Check the weight of soot: PR383 Weight of soot in the particle filter.
– If PR383
≥ 1 g. Apply the procedure for test 8 Manual clearing of the soot weight.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

DESCRIPTION OF THE PROCESS
particle filter regeneration takes place in 3 stages (values given as a guide only):
–Warm-up phase: the engine speed is fixed or varies between 1000 rpm and 1650 rpm.
This phase lasts at least 3 minutes, until the coolant temperature exceeds 80°C.
–Regeneration phase: the engine speed is fixed or varies between 1000 rpm and 1650 rpm. Engine injection
is retarded. The exhaust fumes rise in temperature and burn the soot retained in the particle filter. The particle
filter downstream temperature starts to rise after the particle filter upstream temperature due to the
volume of the particle filter. Then the combustion of the soot stored in the particle filter causes the particle filter
downstream temperature to increase, possibly reaching more than 700°C depending on the amount of soot in
the filter (with a particle filter upstream temperature of approximately 600°C). This phase lasts between 20
and 25 minutes.
–Cooling phase: the engine speed is fixed or varies between 1000 rpm and 1650 rpm.
Engine injection returns to normal and the exhaust gases cool the particle filter.
This phase lasts 3 minutes. At the end of this period, the engine speed returns to idle speed or remains fixed at
1500 rpm.
The process lasts at least 30 minutes (regeneration time will be increased depending on how long it takes for
the coolant temperature to reach 80°C).
CONFIRMING THE REGENERATION PROCESS:
At the end of regeneration, a message appears to announce whether the regeneration was successful:
●Particle filter regeneration finished:
Consult PR1012 Weight of soot after regeneration. If PR1012 is less than 15 g, the particle filter regeneration
completed correctly. If PR1012 is greater than 15 g, a second particle filter regeneration must be performed using
the command in the diagnostic tool and choose command SC017.
IMPORTANT:
Before performing a second After-Sales regeneration of the particle filter, the engine must be allowed to cool
down for 2 hours with the bonnet open.
Do not systematically change the engine oil before a second After-Sales regeneration.
Consult PR848 Number of regeneration failures. If PR848 is greater than 3, change the engine oil.
●Particle filter too full – replace the particle filter: regeneration has failed. The weight of soot in the particle
filter is so great that it is creating back-pressure. Deal with any faults that appear or replace the particle filter.
Run command SC036 Reinitialise programming and select After particle filter replacement.
Check the weight of soot: PR383 Weight of soot in the particle filter.
If PR383
≥ 1 g. Apply the procedure for test 8 Manual clearing of the soot weight.

–Consult PR848 Number of regeneration failures. If this parameter is greater than 3, it is essential to change
the engine oil.
– Explain to the customer the procedure for regeneration when driving to avoid unnecessary repairs: see PART D
in the interpretation of DF312 Speed request.
●Particle filter regeneration failed – run test "Temperature upstream of turbine too low": regeneration
has failed because the temperature upstream of the turbine is too low. Run test 10 Temperature upstream
of turbine too low.
In all cases, carry out the following operations:
– switch off the ignition and wait for the diagnostic tool message (maximum wait 8 minutes): Loss of dialogue
with the computer: EDC16, check the tool connection and the computer supply.
– switch on the ignition and establish dialogue with the injection computer,
– run command SC036 Reinitialise programming,
– depending on the operation performed, select After particle filter regeneration with diag tool, or After
particle filter replacement
– switch off the ignition and wait for the diagnostic tool message (maximum wait 8 minutes): Loss of dialogue
with the computer: EDC16, check the tool connection and the computer supply.
–Then switch on the ignition again, clear the present or stored faults from the computer memory (operation
to be carried out within 3 minutes of switching on the ignition).
Check the weight of soot: PR383 Weight of soot in the particle filter.
If PR383
≥ 1 g. Apply the procedure for test 8 Manual clearing of the soot weight.
If DF308 Clogged particle filter or DF312 Speed request is still present, contact the Techline.
Note:
It is essential to change the engine oil and the oil filter in the following cases:
– following an After-Sales regeneration only if a message on the CLIP diagnostic tool requests it,
– after particle filter replacement following DF311 Number of failed regenerations exceeded (present or stored
before regeneration),
– after a second regeneration (when two successive regenerations).

REINITIALISE PROGRAMMING
NOTESThis command is used to reset the computer parameters according to the type of
operation or component repaired or replaced from the following list:
– the EGR valve,
– the damper valve,
– after replacing the particle filter,
– after particle filter regeneration using the diagnostic tool,
– after injection computer replacement with no backup option,
Ignition on and engine stopped.
To run this command, select scenario SC036 on the CLIP diagnostic tool.
Procedure to be followed:
– on the main screen, select the component to reinitialise after an operation (removal – refitting or replacement of
component),
–select YES then OK to begin reinitialisation,
–select Finish on the Configuration performed screen to return to the main screen,
– end of operation.
– perform a complete powerlatch.
Features of the selections: After particle filter regeneration with diagnostic tool and After replacement of the
particle filter:
After using one of these 2 commands:
– switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Communication
lost with computer: EDC16C36, check the tool connection and computer power supply.
–Then switch on the ignition again and clear the present or stored faults from the computer memory
(operation to be carried out within 3 minutes of switching on the ignition).
– Check the weight of soot: PR383 Weight of soot in the particle filter.
– If PR383
≥ 1 g. Apply the procedure for test 8 Manual clearing of the soot weight.
