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

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.

4) Check the operation of the turbocharger:
a) Attach a vacuum pump to the hose connected to the turbocharger control diaphragm,
Apply a vacuum of 700 mbar < X < 900 mbar:
If there is a leak, replace the turbocharger (diaphragm included).
b) Check the movement and adjustment of the control rod (see MR 364 (Mégane II), 370 (Scénic II) or 395
(Laguna II), Mechanical, 12B, Turbocharging).
If the control rod is sticking, replace the turbocharger.
c) Engine cold and stopped:
Remove the turbocharger inlet duct and check that the compressor turns freely on the axis.
d) If the fault persists:
Check that the exhaust manifold is not leaking.
Check that the exhaust is not blocked.
Carry out the necessary repairs.
5) Check the computer output stage with the solenoid valve connected:
This operation can only be carried out if the checks indicated in step no. 2 are not conclusive.
→Or using a voltmeter:
Connect the voltmeter earth lead to connection 3FB (Laguna II and Mégane II) or 3FB1 (Scénic II) of
component 1475 and the positive lead to connection 3MG.
Clear any solenoid valve fault then run command AC004:
The voltmeter should display ten cycles of two successive voltages ~ = battery voltage X current OCR*.
Either: ~ 2.5 V (OCR* of 20%) then ~ 8.7 V (OCR* of 70%).
→Or using an oscilloscope (range 5 V/division and time base 1 ms/division):
Connect the oscilloscope earth lead to the battery earth and the positive test pin to connection 3FB (Laguna II
and Mégane II) or 3FB1 (Scénic II) of component 1475.
Clear any solenoid valve faults, then run command AC004:
the oscilloscope should display a square wave signal of 12.5 V in amplitude at a frequency of 140 Hz
(with an OCR* passing from ~ 20 to ~ 70%).
if the measurement is correct, replace the solenoid valve.
if the measurement does not show any control or continuous voltage, contact the techline.
