PARAMETER
DEFINITIONThese parameters are shown in Km.
NOTESSpecial notes:
These parameters must only be interpreted for DF312 Speed request if it is present
or stored.
These parameters exist only in Vdiag48.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C, without electrical consumers
In the event of a fault, consult the interpretation of fault DF312 Speed request.
These parameters are used for looking up the history of the last ten particle filter warning light activations
Each parameter from PR784 to PR793 contains a record of the vehicle mileage when the particle filter warning
light illuminates. The appearance of fault DF312 Speed request is associated with each of these parameters.
PR784 to PR793 operate through successive copying (when the particle filter warning light comes on, the value of
PR784 is copied to PR785, the value of PR785 is copied to PR786 and so on).
When there are more than ten records, the value of PR793 DF312 record no. 10 is cleared. The new mileage is
allocated to PR784.
If none of the parameters between PR784 and PR793 is available in the sub-function, this means that no data has
been saved. The parameters appear in the sub-function when they have a value above zero.

These parameters are used so that the history of the last ten failed regenerations when driving is known.
Each parameter between PR794 and PR803 contains the vehicle mileage when particle filter regeneration fails
when driving. each parameter relates to an engine status. They are recorded simultaneously (for example PR797
Regeneration failure record No. 4 is associated with ET709 Engine status record no. 4).
PR794 to PR803 operate through successive copying (when regeneration fails whilst driving, the value of PR794
is copied to PR795, the value of PR795 is copied to PR796 and so on).
When there are more than ten records, the value of PR803 Regeneration failure record no. 10 is overwritten.
The new mileage is allocated to PR794.
If none of the parameters between PR794 and PR803 is available in the sub-function, this means that no data has

Each parameter from PR816 to PR825 records the mileage at the start of particle filter regeneration, for which the
request status is recorded by ET742 Stored reg.* request status no. 1 to ET751 Stored reg.* request status
no. 10 (for example PR819 Stored regeneration start no. 4 is associated with ET745 Stored reg. request
status no. 4).
Each time a new regeneration is started when driving, the vehicle mileage is recorded in PR816, as well as its
status in ET742 Stored reg.* request status no. 1.
PR816 to PR825 operate through successive copying (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 stored items, the value of PR825 Regeneration start record no. 10 is overwritten.
The new mileage is allocated to PR816.
If only the parameter PR816 Regeneration start record no. 1 is available in the sub-function and it has no value,
this indicates that no record was made.
If a record has been made, it will have a value above zero.

PR1012WEIGHT OF SOOT AFTER REGENERATION
PARAMETER
DEFINITIONThis parameter indicates the weight of soot, in g, in the particle filter after a
regeneration.
NOTESConsult this parameter after using SC017 Particle filter regeneration.
Conformity check: Engine stopped and the ignition on, or the engine running and the 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, it is necessary to perform a second particle filter regeneration using command
SC017 Particle filter regeneration (see interpretation of commands).
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 carry out the usual engine oil change before a second After-Sales regeneration (see SC017 Particle filter
regeneration).

SC017PARTICLE FILTER REGENERATION
NOTESOnly run this command after 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 (Megane II ph2), MR370 (Scenic II
ph2), Mechanical, 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 that can withstand the 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.
IMPORTANT
– 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 time 8 minutes) Communication lost
with computer: EDC16C36, check the tool connection and the computer supply. before switching on the
ignition again.
PROCEDURE TO BE FOLLOWED:
Before a particle filter regeneration, check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
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, and what
operations need to be carried out (filter replacement, whether an oil service is required, etc.).

DESCRIPTION OF THE PROCESS
Particle filter regeneration takes place in 3 stages (values given as a guide only):
–Heating phase: the engine speed is fixed or fluctuating around 2000 rpm.
This phase lasts between 8 and 14 minutes, until the coolant temperature exceeds 70°C.
–Regeneration phase: the speed is fixed or varies around 2000 rpm. Engine injection is retarded. The exhaust
fumes rise in temperature and burn the soot retained in the particle filter. Then the combustion of the soot stored
in the particle filter causes the particle filter upstream temperature to increase, possibly reaching 600°C
depending on the amount of soot in the particle filter. This phase lasts 28 minutes.
–Cooling phase: the engine speed decreases to 1250 rpm then increases to 1750 rpm.
Engine injection returns to normal and the exhaust gases cool the particle filter.
This phase lasts 3 minutes.
The procedure lasts at least 40 minutes, and varies depending on the time taken to reach a coolant temperature
of 70°C.
VALIDATING 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.
