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.

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.
Only for Vdiag 50:
– Change the engine oil if a message on the instrument panel requests it.
For the other VDiag:
–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.
– 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).
– Check the weight of soot: PR383 Weight of soot in the particle filter.
– If PR383
≥ 1 g. Apply the procedure of test 12 Manual clearing of the weight of soot.
Only for Vdiag 50:
– Change the engine oil if a message on the instrument panel requests it.
– For the other Vdiags:
–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 replacement
– 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.
–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 test procedure 12 Manual clearing of the weight of soot.
If DF308 Particle filter clogged or DF312 Speed request is still present, contact 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,
– following particle filter replacement,
after a second regeneration (when two successive regenerations).

NOTESBefore analysing this customer complaint, check that there are no faults, and the
conformity (or otherwise) of the parameters and statuses, using the diagnostic
tool.
If the customer complaint is not eliminated, perform the following checks.
IMPORTANT
In the case of engine overheating to above 118°C, the computer deliberately limits the fuel flow (overheating
warning light lights up from 115°C).
Please observe the cleanliness guidelines and safety advice.
Is the poor performance accompanied by smoke?
Check the conformity of the fuel used by running test 11 Diesel fuel conformity check.
If the diesel fuel is not correct:
– Replace the diesel fuel.
– Change the diesel filter.
– Bleed the low and high pressure diesel circuit.
Test the high pressure fuel circuit:
Run the scenario SC035 High pressure fuel circuit fault finding (see Interpretation of commands).
Check that the injectors are correctly fitted (presence and conformity of the sealing washer).
Checking procedure:
– Take a straightedge approximately 40 cm long and place it on the 4 injectors. The straightedge should rest on
the 4 injectors.
– If 1 injector protrudes, remove the injector and check that the washer is correct.
– If one injector does not touch the straightedge (clearance of more than 1 mm), remove the injector and check
that the washer is present.
– Clean the injector wells and the injector, refit the injector with the correct sealing washer.
