Run test 2 Air line at the turbocharger.
Run test 6: Turbocharger control solenoid valve check.
Is the vehicle equipped with a particle filter?
Start the engine and warm it up at idle speed for 10 min.
IMPORTANT
If the air filter was previously removed, refit it before starting the
engine (risk of aspirating foreign bodies into the air inlet circuit).
Perform several rapid and brief accelerations under no load.
Note:
The presence of smoke is often normal.
It is the quantity, density, colour and persistence that are deciding
factors.
Is the exhaust outlet producing abnormal smoke?Perform the fault finding of the
"particle filter" function, refer to the
TESTS or corresponding ALP
Refer to test 7 Turbocharger.The turbocharger is not faulty. There is probably another fault
in the engine. Consult the TEST or the corresponding ALP

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)

Is the engine running normally?The exhaust pipe is not the cause of
the fault, repeat the engine fault
finding (see Customer complaints -
Fault finding chart (ALP)).
Retighten the catalytic converter.
Loosen or disconnect the intermediate chamber on the catalytic
converter side. Place a wooden block between the two parts if
necessary.
Start the vehicle and check if the engine runs better.

TEST2

High pressure circuit check
Note:
Depending on the vehicle type, the best visual access will be either from
above or from below.
Visually inspect the condition of the following components:
– outlet pipe of the compressor to the turbocharging air cooler,
– outlet pipe of the turbocharging air cooler to the inlet manifold,
– inlet manifold,
– temperature and pressure sensors.
Is one of these components incorrect (disconnected, cut, bent,
pierced or kinked pipes)?
Replace the defective parts
(see MR 364 (Mégane II) or
370 (Scénic II),
Mechanical, 12B,
Turbocharging). Exhaust system check
Visually inspect the condition of the following engine sections:
– from the exhaust manifold circuit to the turbocharger turbine,
– from the turbine outlet pipe to the end of the exhaust pipe,
– from the inlet manifold to the EGR valve
– check that the temperature and pressure sensors are connected.
Do some of these components have black or white marks on them?

TEST3 Low pressure circuit check
HIGH PRESSURE PUMP
Check the fuel filter:
– Conformity of the fuel filter (correct part number and RENAULT filter),
– positioning and clogging condition of the filter cartridge,
– Positioning and condition of the seals.
– if there is metal swarf in the filter:
Replace the fuel filter, bleed the circuit and continue the fault finding procedure.
●Supplying the injection system with fuel from an additional tank.
This operation aims to detect possible faults in the low pressure supply system of a vehicle by replacing it entirely with
an additional tank.
Mode:
– Disconnect the diesel fuel supply pipe at the fuel filter inlet and seal it with a plug.
– Connect a pipe to the fuel filter inlet and insert the other end in a clean container of approximately 5litres.
– Disconnect the diesel return pipe at the diesel temperature sensor (pump return and injector return join), and block
it using a plug.
– Connect a transparent pipe to the union of the diesel temperature sensor, and insert the other end in the container.
– Fill the container with clean diesel fuel.
– Start the engine and let the system drain itself of its air (there must not be any air bubbles in the return pipe).
Is the customer complaint still present?If the low pressure circuit is in order, reconnect
the various pipes of the low pressure circuit and
repeat the fault finding chart fault finding or of
the fault that referred you to this test.
Are the low pressure circuit connections in order
and in good condition?Carry out the necessary repairs.

TEST4 Checking the turbocharged air inlet circuit
Engine stopped:
Check the sealing of the low and high pressure air circuits (air leaks in or out, upstream/downstream of the
turbocharger).
Check the parts that are abnormally greasy of the circuit and reveal a lack of tightness.
Check:
– The condition and fitting of the ducts (foreign bodies, clogged, displaced, kinked, broken, pierced, cut, tightness
of the mounting bolts, etc.).
– the presence, condition and fitting of the seals,
– the presence and tightening of the clamps,
– the fitting of the turbocharger pressure sensor.
– the pipe and take-off point between the air duct and the turbocharging sensor
Carry out the necessary repairs
Checking the air filter.
Check:
– that the air filter unit inlet and outlet are not blocked,
– the condition and the assembly of the air filter unit (disconnected, broken, pierced, etc.),
– the cleanliness, conformity and the non-distortion of the filter element,
– The air flowmeter: run test 5: Air flowmeter.
Carry out the necessary repairs.

Check:
– the condition of the damper valve,
– the tightening of the mounting bolts,
– cracks in the damper valve.
Carry out the necessary repairs.
Replace if necessary.
Check that there is no leak at the exhaust manifold, in particular at the exhaust manifold/turbocharger connection.
Check the exhaust system: run test 1 Exhaust pipe check in ALP2.
Carry out the necessary repairs.
Carry out a visual inspection of the EGR circuit sealing.
Note: the operating play in the EGR heat exchanger valve shaft produces small black marks due to a slight leak
of no importance. Do not replace this part.
Replace if necessary.
Check the condition of the intercooler:
– clogging,
– leaks (vehicle stationary, stabilise the engine speed between 3500 rpm and 4000 rpm and check that there are
no leaks).
Replace if necessary.
Check that the take-off point for the turbocharging pressure sensor is not blocked.
