If all the criteria are met, the computer enters regeneration mode. The injection programming is adjusted in order to
raise the target exhaust gas temperature between 550 and 650°C.
This temperature allows the particles accumulated in the filter to be partially or completely burnt (regenerated).
Regeneration efficiency depends on the particle filter inlet temperature and the time spent in regeneration mode.
Regeneration can be carried out automatically when driving if the weight of soot is less than 70 g and if the number
of regeneration attempts when driving is less than 11 (only for Vdiag 48).
If the weight of soot is greater than 70 g, the user will have to request an After-sales regeneration.
This regeneration is carried out in the workshop. Always follow the instructions written in the interpretation of
commands (SC017 Particle filter regeneration) to perform regeneration in complete safety.
After an After-sales regeneration, always reconfigure certain parameters in the computer using command SC036
Reinitialise programming (see "interpretation of commands").
Warning light management:
Instrument panel display
The computer displays certain information on the instrument panel relating to engine operation. This involves six
functions:
– the pre-postheating warning light,
– the coolant temperature 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),
– the particle filter specific warning light (F9Q816 engine only).
These six functions are represented by 6 warning lights and/or messages displayed by the on-board computer.
In addition, certain warning lights are, when lit, accompanied by a spoken message on vehicles fitted with a voice
synthesiser (refer to the driver's handbook).
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.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 in the driver's handbook.
After replacing it, always reconfigure certain parameters in the computer using command SC036 Reinitialise
programming (see "interpretation of commands").

AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

STOREDPARTICLE FILTER UPSTREAM TEMP.* SENSOR
CO.1: Open circuit or short circuit to +12 V
CC.0: Short circuit to earth
NOTESConditions for applying fault finding procedures to stored faults:
The fault becomes present if:
– ignition is on (CC.0),
– following a road test, engine warm (CO.1).
Special notes:
If the fault is present:
– particle filter regeneration is inhibited,
–the level 1 warning light is lit,
–the OBD warning light comes on after three consecutive driving cycles (start
+5 seconds, switch off the ignition and wait 1 minute).
IMPORTANT
The particle filter upstream temperature sensor only measures temperatures
above 50°C.
Use the Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– particle filter regeneration is inhibited,
– blue/white smoke and black particles coming from the exhaust,
the OBD warning light will illuminate after three consecutive driving cycles (start + 5
seconds, switch off the ignition and wait 40 seconds).
Priorities when dealing with a number of faults:
– DF315 Particle filter diff.* pressure sensor if present or stored
IMPORTANT
In the long term, this fault may lead to premature wear and a greater risk of
turbocharger failure.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
