PR038RAIL PRESSURE
PARAMETER
DEFINITIONThis parameter indicates the rail pressure in bar.
NOTESThere must be no present or stored faults.
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.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Conformity check with engine stopped and ignition on
The rail pressure value is:
0 bar < PR038 < 90 bar if the coolant temperature < 30°C
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:
At idle speed: PR038 = 270 bar ± 20 bar
Full load: PR038 = 1700 bar ± 20 bar
In the event of a fault, consult the interpretation of fault DF007 Rail pressure sensor circuit.

If any of the connections are faulty and there is a repair method (see Technical Note 6015A, Electrical wiring
repair, Wiring: precautions for repairs), repair the wiring; otherwise replace the wiring.
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 greater 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:
The low and high pressure air circuit is sealed and not obstructed: the pipes and mounting clamps are present
and tightened, turbocharging pressure sensor, intercooler, etc. are fitted.
Check that the damper valve is not jammed closed.
Repair if necessary.

SC017PARTICLE FILTER REGENERATION
NOTESOnly run this command after 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 (Megane II ph2), MR370 (Scenic II
ph2), Mechanical, 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 that can withstand the 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.
IMPORTANT
– 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 time 8 minutes) Communication lost
with computer: EDC16C36, check the tool connection and the computer supply. before switching on the
ignition again.
PROCEDURE TO BE FOLLOWED:
Before a particle filter regeneration, check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
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, and what
operations need to be carried out (filter replacement, whether an oil service is required, etc.).

2. Turbocharger control circuit check:
– With the engine stopped, make sure that the control rod is in the resting position.
– Start the engine and make sure that the control rod actuates to the upper stop.
(when the engine is switched off, the control rod should return to the rest position)
If the control rod does not move correctly, carry out the following checks:
1) Control vacuum 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 does not reach 400 mbar ± 150: check the vacuum pressure circuit from the vacuum pump.
– Stop the engine, reconnect the intake 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, contact the Techline.
3) Solenoid valve operation check:
– Connect the pressure gauge to the solenoid valve outlet union.
– Start the engine and run it at a stable idle speed.
If the vacuum does not reach 400 mbar ± 150, replace the solenoid valve.
