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.).

TURBOCHARGING SOLENOID VALVE
NOTESthis command is used to check the turbocharging circuit.
This command checks that the turbocharger and the control circuit are working properly.
Introduction
1- check the sealing of the high-pressure air circuit:
Pipes not joined or pierced, pressure sensor disconnected or poorly fitted (seal present), intercooler pierced. To
check the intercooler: with the vehicle stopped, stabilise the engine speed between 3500 rpm < X < 4000 rpm
and check that there are no leaks.
Check the resistance of the turbocharging pressure relief solenoid valve between connections 3FB and 3MG.
Replace the solenoid valve if its resistance is not: 14.7 Ω < X < 16.1 Ω at 20°C.
Check the injection computer connections.
Check the continuity and absence of interference resistance of connection 3MG between components 120
and 1475.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for + 12 V after relay on connection 3FB of component 1475.
2- turbocharger control circuit check
– with the engine stopped, check that the control rod is (in the rest position the control rod is retracted),
– start the engine and check that the control rod disengages and pulls on the turbocharger geometry (when the
engine is stopped, the control rod should return to the rest position).
– if the control rod does not move correctly, carry out the following checks:
1) Vacuum pressure command check:
– Disconnect the solenoid valve inlet hose and connect it to a pressure gauge.
– Start the engine and run it at a stable idle speed.
– if the vacuum is not between 700 mbar < X < 900 mbar, check the vacuum circuit from the vacuum pump.
– Stop the engine, reconnect the inlet hose and go to step no. 2.
2) Solenoid valve control check:
– Disconnect the solenoid valve outlet hose.
– Start the engine and run it at a stable idle speed.
– Place your hand on the solenoid valve and block the outlet union with your thumb.
– If there is no perceptible vibration of the solenoid valve, check that the computer output is working correctly
(step 5) and check solenoid valve operation:
– Connect the pressure gauge to the solenoid valve outlet union.
– Start the engine and run it at a stable idle speed.
if the vacuum is not between 700 mbar < X < 900 mbar, replace the solenoid valve.

DAMPER VALVE
NOTESCarry out this interpretation:
–after DF226 Damper valve,
– or after a customer complaint (starting faults, poor performance).
Ignition on and engine stopped.
Check the continuity, insulation and absence of interference resistance on the following connections:
– connection code NT (Laguna II) between component 1461 and the earth NT.
– connection code N (Scénic II and Mégane II) between component 1461 and the earth N.
– connection code 3FB (Laguna II) between components 1461 and 597.
– connection code 3FB2 (Scénic II) between components 1461 and 1337.
– connection code 3FB (Mégane II) between components 1461 and 1337.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for + 12 V on connection 3FB (Laguna II and Mégane II) or 3FB2 (Scénic II) of component 1461.
Repair if necessary.
Check for earth on connection N (Scénic II and Mégane II) or NT (Laguna II) of component 1461.
Repair if necessary.
Check that the damper valve is open.
If not, clean or replace the air vent unit.
Actuate the valve using command AC012 and check its travel and rest position.
Check the operation of the computer output stage with a voltmeter:
Actuate the valve with command AC012.
If the solenoid valve opens (vacuum pump pressure gauge returns to atmospheric pressure), go to step C.
Otherwise, with the solenoid valve connected, check the operation of the computer output stage with a voltmeter
between connections 3FB (Laguna II and Mégane II) or 3FB2 (Scénic II) and N (Scénic II and Mégane II) or
NT (Laguna II) of component 1461.
The voltmeter should display three ON-OFF cycles (12.5 V then return to 0 V).
If the measurement is correct, replace the damper valve.
If the measurement does not show any operation, contact the Techline.

TEST8 Manual clearing of the soot weight
Note: In certain cases, this procedure is to be carried out only after replacement of the particle filter or after an
After-sales regeneration of the particle filter.
– Start the engine.
– Raise the engine coolant temperature.
– Read the coolant temperature with PR064 Coolant temperature until a value greater than 65ºC is obtained.
– Accelerate the engine to 4000 rpm and maintain this speed for 5 minutes.
–After 5 minutes, release the accelerator and stop the engine.
– Switch on the ignition.
– Run command SC036 Reinitialise programming and select After particle filter replacement or After
particle filter regeneration (as appropriate).
– 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).
