PR1012
WEIGHT OF SOOT AFTER REGENERATION
PARAMETER
DEFINITIONThis parameter indicates the weight of soot in g present in the particle filter after
a regeneration.
NOTESThis parameter is to be consulted after using SC017 Particle filter regeneration.
Conformity check with the engine stopped and ignition on, or the engine running and engine coolant
temperature > 80°C, without electrical consumers
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 command SC017
Particle filter regeneration.
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 perform a routine oil change before a second After-Sales regeneration (see SC017 Particle filter
regeneration).
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

PARTICLE FILTER REGENERATION
NOTESonly run this command after the interpretation of the following faults:
– df308 clogged particle filter.
– df311 failed regenerations limit exceeded.
– df312: speed request.
WARNING
it is essential to observe the health and safety regulations (see mr364 (mégane ii ph2), mr370 (scénic ii
ph2), mr 395 (laguna ii ph2), mechanical systems 19b exhaust, particle filter: cleaning) and observe the
following procedure.
SAFETY INSTRUCTIONS TO BE FOLLOWED:
The regeneration causes exhaust fumes and high temperatures.
The vehicle must be outside during regeneration.
If it is not possible to carry out regeneration outside, use an extractor fan which can withstand very high
regeneration temperatures (400°C at the exhaust outlet).
Perform regeneration on a surface free from fire risks (oil, dry leaves, etc.).
Nothing should be left in the vicinity of the exhaust pipe.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
WARNING:
– Check the engine oil level before running the command to avoid any engine racing. The oil level must
be between the minimum threshold and the middle level on the oil dipstick.
– Before performing a particle filter regeneration, it is essential to deactivate the air conditioning
compressor (risk of engine damage) and all the electrical consumers.
IF NECESSARY:
Regeneration can be stopped by briefly pressing the vehicle start button twice (less than 3 seconds).
Switch off the ignition and wait for the diagnostic tool message (maximum wait 8 minutes): Loss of dialogue
with the computer: EDC16C3, check the tool connection and the computer supply, before switching the
ignition back on.
PROCEDURE TO BE FOLLOWED:
To run this command, select the command mode on the diagnostic tool, and select command SC017 Particle
filter regeneration.
When regeneration is complete, a message will indicate whether regeneration was successful or if any other
operations need to be carried out (filter replacement, whether an oil change is required, etc.).

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).
