If regeneration whilst driving has not been possible, the driver should request After-Sales regeneration in the
following cases:
– the soot weight is greater than 56 g for Vdiag 18.
– the soot weight is greater than 59 g or the number of failed regenerations is greater than 10 for Vdiag 1C
and 20.
This regeneration is carried out in the workshop. It is essential to follow the instructions described in the
interpretation of commands SC017 Particle filter regeneration. To carry out regeneration safely (see Te c h n i c a l
Note 5040A, Recommendations for particle filter regeneration).
Warning light management:
Instrument panel display
The computer manages the data display on the instrument panel relating to engine operation. This involves six
functions:
– the pre-postheating warning light,
– the coolant temperature warning light or warning message;
– the level 1 fault warning light (non-critical fault),
– the level 2 fault warning light (emergency stop),
– the OBD warning light (European On Board Diagnostic),
– particle filter warning message or light.
These six functions are represented by 4 or 5 warning lights and/or messages displayed by the trip computer.
In addition, for vehicles fitted with a voice synthesiser the illumination of some warning lights may be accompanied
by a spoken message (refer to the Driver's Handbook for the vehicle concerned).
A 3 second visual inspection (automatic test procedure managed by the instrument panel) is carried out by the
injection computer when the ignition is switched on.
Orange pre-post heating/non-critical fault SERVICE warning light (level 1)
This light is used both as an in-operation indicator light and as a system fault indicator:
– Continuously lit with + after ignition feed:
Indicates plug preheating (this light goes out when preheating is complete and the engine is able to start).
– Continuously lit accompanied by the message Check injection or Electronic fault:
Indicates a level 1 fault (involving operation of the injection system in defect mode).
The driver should carry out repairs as soon as possible. IMPORTANT
The particle filter must be replaced after a period of time which largely depends on the grade of engine oil used.
This information is provided in the vehicle's Driver's handbook.
After replacing the particle filter, it is essential to reconfigure certain parameters in the computer (see SC036
Reinitialise programming).

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– the level 1 warning light is lit,
– particle filter regenerations when driving are inhibited.
Use bornier Ele. 1681 for all operations on the engine management computer
connector.
Priorities when dealing with a number of faults:
Firstly, deal with the following faults:
– DF308 Particle filter clogged if it is present or stored,
– DF226 Damper valve circuit if it is present or stored,
– DF272 EGR valve control circuit if it is present or stored.
The fault appears after a certain number of failed regeneration attempts while driving (between 10 and 12
for MEGANE II and SCENIC II; between 6 and 8 for LAGUNA II).
–Run TEST 2 Air path at the turbocharger.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
– Carry out an After-Sales regeneration.
– Follow the procedure for command SC017 Particle filter regeneration (see Interpretation of commands).
Carry out an oil change if the particle filter is replaced.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another 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.).
