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.

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.

ENTER INJECTOR CODES
NOTESrun this command after replacing the injectors but only if the vehicle is configured with
ima.
(ET104 Injector code use to YES).
If this command is not run, fault DF276 Injection code programming will be present.
WARNING
The letters J and Q, and figures 0 and 9 are not used in IMA coding.
If these characters are used the entry will be invalid.
Cylinder no. 1 is the cylinder located on the engine flywheel end.
Procedure to be followed:
– Make a note of the 6-character alphanumeric codes engraved on the upper section of the injector bodies.
– Use command SC002.
– Select the cylinder number for the cylinder concerned in the Desired, column, then confirm.
– enter the injector code displayed for the cylinder.
– Enter the new codes for each cylinder, then confirm.
– When the command is completed, the modified codes appear in the Current column.
– Check that the codes correspond to those read earlier.
– If the codes entered do not appear in either the Current column or the Desired column, check the codes read
and make sure that the data has been entered correctly.
The possible confusions are:
digit "1" with the letter "i"
figure 8 with the letter b
figure 5 with the letter s
- Exit fault finding mode.
- Switch off the ignition and wait for 1 min. Switch the ignition back on and check for faults.
-DF276 Injector code programming should be stored.
If fault DF276 Injector code programming is present, the command has not run correctly.
Start the procedure again and follow the instructions.
If the codes are still not accepted, check that the computer has been put on standby correctly:
Switch off the ignition and wait for 1 minute.
if the warning light flashes when the ignition is switched off, the computer has not been put on standby and the
command will be ignored.
If all these checks still do not enable the command to be confirmed, contact the Techline.

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.
