STATUS DEFINITIONStatuses ET742 to ET751 correspond to the causes of the regeneration request. They
are associated with parameters PR816 "Stored regeneration start No. 1" to PR825
"Stored regeneration start No. 10" which contain the record of the vehicle mileage at
the start of regeneration (eg. PR745 "Stored regeneration start No. 4" is associated
with "ET709 Stored regeneration request status no. 4").
NOTESSpecial note:
These statuses should only be interpreted for ALP9: Particle filter warning light
comes on too frequently.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80 °C
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

PARAMETER
DEFINITIONThese parameters are shown in Km.
NOTESSpecial notes:
Interpret these parameters only for ALP9 Particle filter warning light comes on too
often.
Conformity check with the engine stopped and the ignition on, or with the engine running and the engine
coolant temperature > 80°C
These parameters are used so that the history of the last ten activations of the particle filter warning light are
known.
For VDIAG 58, 18 and 1C
Each parameter between PR816 and PR825 contains the vehicle mileage when particle filter regeneration starts
when driving. Each parameter is connected with a "Rege* request status record". They are recorded
simultaneously (for example, PR819 is associated with ET745 Rege* request status record no. 4).
Each new recorded value is saved under the next PR (PR+1).
When all ten parameters have a value other than zero, and a new regeneration starts when driving, the mileage
information for PR816 is cleared and replaced with the new value.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

For VDIAG 5C and 20
Each parameter from PR816 to PR825 records the mileage when particle filter regeneration starts and the status
of each request is recorded by ET742 Rege* request status record no. 1 to ET751 Rege* request status
record no. 10 (for example, PR819 is associated with ET745 Rege* request status record no.4).
Each time a new regeneration when driving is started, the vehicle mileage is recorded in PR816, as well as its
status in ET742 Rege* request status record no. 1
PR816 to PR825 operate through successive feedback (when regeneration starts, the value of PR816 is copied to
PR817, the value of PR817 is copied to PR818 and so on).
When there are more than ten records, the value of PR825 is overwritten.
The new mileage is allocated to PR816.
If only parameter PR816 is available in the sub-function and it has a value of zero, this means that no record was
made.
If a recording has been made, it will have a value above zero.
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.

TEST8 Manual clearing of the soot weight
Note: In certain cases, this procedure is to be carried out only after replacement of the particle filter or after an
After-sales regeneration of the particle filter.
– Start the engine.
– Raise the engine coolant temperature.
– Read the coolant temperature with PR064 Coolant temperature until a value greater than 65ºC is obtained.
– Accelerate the engine to 4000 rpm and maintain this speed for 5 minutes.
–After 5 minutes, release the accelerator and stop the engine.
– Switch on the ignition.
– Run command SC036 Reinitialise programming and select After particle filter replacement or After
particle filter regeneration (as appropriate).
– 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, clear the present or stored faults from the computer memory (operation
to be carried out within 3 minutes of switching on the ignition).
