RAIL PRESSURE
PARAMETER
DEFINITIONThis parameter indicates the rail pressure in bar.
NOTESNo faults should be present or stored.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– after a customer complaint (starting faults, poor performance, stalling, etc.).
– after interpretation of command AC225 Rail pressure regulator.
Special notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on.
The rail pressure value is between:
0 < PR038 < 10 bar
Default value: 250 bar.
In the event of a fault, consult the interpretation of fault DF007 Rail pressure sensor circuit.
Conformity check with engine running, engine coolant temperature > 80°C.
The rail pressure value is (engine at idle speed):
PR038 = ~ 315 bar
Default value: 250 bar.
In the event of a fault, consult the interpretation of fault DF007 Rail pressure sensor circuit.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

CONTINUED
Vehicle with ignition on, and the engine stopped for over 1 minute:
Compare the values of PR041 and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.1 bar,
check the value of PR035 Atmospheric pressure by comparing it with the reading on a vehicle in the workshop
which is correct.
If the value of PR035 Atmospheric pressure is not correct (difference greater than 0.1 bar between
the 2 vehicles), contact the Techline.
Otherwise (when the value PR035 Atmospheric pressure is correct), change the turbocharging pressure
sensor.
If the difference between PR041 and PR035 Atmospheric pressure is less than 0.1 bar.
Start the engine, with the engine idling:
Compare the values of PR041 and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.2 bar.
Check the air inlet circuit:
absence of leaks or blockages in the low and high pressure air circuit: ducts, presence and tightness of the
mounting clips, mounting of the turbocharger pressure sensor, intercooler, etc.
Check that the damper valve is not jammed closed.
Repair if necessary.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

PARAMETER
DEFINITIONThese parameters are shown in Km.
NOTESSpecial notes:
Interpret these parameters only for ALP9 Particle filter warning light comes on too
often.
Conformity check with the engine stopped and the ignition on, or with the engine running and the engine
coolant temperature > 80°C
These parameters are used so that the history of the last ten activations of the particle filter warning light are
known.
For VDIAG 58, 18 and 1C
Each parameter between PR816 and PR825 contains the vehicle mileage when particle filter regeneration starts
when driving. Each parameter is connected with a "Rege* request status record". They are recorded
simultaneously (for example, PR819 is associated with ET745 Rege* request status record no. 4).
Each new recorded value is saved under the next PR (PR+1).
When all ten parameters have a value other than zero, and a new regeneration starts when driving, the mileage
information for PR816 is cleared and replaced with the new value.
AFTER REPAIRCarry out a road test, then 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.).

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.
