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.).

VP036INHIBIT FUEL SUPPLY
NOTESThis command enables you to disable the supply to the injectors.
This command is carried out with the engine switched off, and ignition on.
This command allows the injectors to be locked, so that starting is not possible.
Command VP036 allows the engine compressions to be checked in complete safety without disconnecting the
injector connectors or the TDC sensor.
Procedure to follow: (cylinder no. 1 is located on the flywheel end).
– Remove all the heater plugs, connect the compression gauge.
– Position the gear lever in neutral (manual gearbox) or on position P (automatic gearbox).
– Depress the brake pedal and maintain this position.
– Activate command VP036.
– Try to start the vehicle.
– Check the engine compressions.
Start the procedure again on another cylinder.
WARNING
Keep the brake pedal depressed for the length of the test.
Re-establish control of the injectors using command VP037 Stop fuel supply inhibition.

ALP4 Poor performance
NOTESBefore analysing this customer complaint, check that there are no faults, and the
conformity (or otherwise) of the parameters and statuses, using the diagnostic
tool.
If the customer complaint is not eliminated, perform the following checks.
IMPORTANT
In the case of engine overheating to above 118°C, the computer deliberately limits the fuel flow (overheating
warning light lights up from 115°C).
Please observe the cleanliness guidelines and safety advice.
Is the poor performance accompanied by smoke?
Check the conformity of the fuel used by running test 11 Diesel fuel conformity check.
If the diesel fuel is not correct:
– Replace the diesel fuel.
– Change the diesel filter.
– Bleed the low and high pressure diesel circuit.
Test the high pressure fuel circuit:
Run the scenario SC035 High pressure fuel circuit fault finding (see Interpretation of commands).
Check that the injectors are correctly fitted (presence and conformity of the sealing washer).
Checking procedure:
– Take a straightedge approximately 40 cm long and place it on the 4 injectors. The straightedge should rest on
the 4 injectors.
– If 1 injector protrudes, remove the injector and check that the washer is correct.
– If one injector does not touch the straightedge (clearance of more than 1 mm), remove the injector and check
that the washer is present.
– Clean the injector wells and the injector, refit the injector with the correct sealing washer.
– The tightness seal and the condition of the inlet circuit: run test 4: Turbocharged air inlet circuit check.
– The condition of the air flowmeter, run test 5 Air flowmeter.
– The turbocharger, run the following tests:
– test 2: Air path at the turbocharger,
– test 6: Turbocharger control solenoid valve check,
– test 7: Turbocharger.

ALP11 Particle filter warning light comes on too often
NOTESThis ALP is specific to Vdiag48.
Before dealing with this customer complaint, check that there are no faults
except DF312 Speed request, and check the conformity (or otherwise) of the
"parameters" and "statuses" using the diagnostic tool. Deal with the other faults
first.
If the customer complaint is not eliminated, perform the following checks.
Have the last 10 regeneration attempts failed?
Is the mileage of PR412 Mileage of last successful
regeneration less than all the parameters of group 2? (PR794
to PR803 Stored regeneration failure no. 1 to no. 10)Is at least one status in group 1
= STATUS4?
Symptom not
confirmed
Are all the regeneration failures linked to engine cut-off?
See parameter ET706 Stored engine status no.1 to ET715
Stored engine status no.10 (E.g. ET706 STOPPED)
Check the exhaust pipe for leaks or blockage. Repair if
necessary.
Perform After-Sales regeneration if it was not performed
previously (see Interpretation of commands, SC017 Particle
filter regeneration)

WARNING
During this operation, it is essential to:
– refrain from smoking or bringing incandescent objects close to the work area,
– protect yourself against fuel splashes due to residual pressure in the pipes,
– wear safety goggles with side guards,
– wear leaktight gloves (Nitrile type).
IMPORTANT
– To avoid any corrosion or damage, protect the areas on which fuel is likely to run.
– To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components
exposed to the open air.
Preparations:
Weigh an empty 1300 ml plastic cup (part no. 77 11 171 413) with its cover (part no. 77 11 171 416) using
electronic scales such as those used in body paint workshops (example: PANDA part no. 77 11 224 995). Record
the weight of the empty plastic cup.
This type of plastic cup is used to prepare paint.
Take a 1 l fuel sample from the diesel fuel filter outlet (see MR 364 (Mégane II ph2), Mechanical, 19C, Tank,
Fuel tank: Draining, or MR 370 (Scénic II ph2), Mechanical, 19C, Tank, Draining the fuel tank), using a
pneumatic transfer pump (part no. 634-200) and place it in the 1300 ml plastic cup.
Cover the plastic cup with its cover and let the fuel settle for approximately 2 minutes.
Is the fuel cloudy or does it
separate into two parts?Presence of water in diesel fuel, the fuel is not compliant.
Drain the fuel circuit, including the tank (see MR 364
(Mégane II ph2), Mechanical, 19C, Tank, Fuel tank:
Draining, or MR 370 (Scénic II ph2), Mechanical, 19C,
Tank, Draining the fuel tank).
