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.
Check the sealing and condition of the inlet circuit by running Test 4 Turbocharged air circuit check.
Check the low pressure circuit
check the engine parameters:
– Check the update of the engine management computer calibration (last calibration).
– Check the conformity of the IMA codes (using the Identification screen on the Clip diagnostic tool).
– Check the charging circuit (see Technical Note 6014A Checking the charging circuit)
– To check the conformity of the engine speed signal, check:
– The wiring.
– The flywheel position and the condition of the flywheel teeth.
– The position and tightness of the engine speed sensor.
– Check the fuel flow correction from station to station, run Test 10 Poor injector operation.
Check the connections and wiring of the injectors.
Check the connections and wiring of the engine management computer to the injectors.
Repair if necessary.

Check the high pressure circuit (external leaks) (see the end of ALP6 Fuel circuit external leaks)
Check the timing setting (and the position of the high pressure pump pinion)
Check the lower engine:
– Check the compressions using the CLIP diagnostic tool, use command VP036 Fuel supply inhibition.
– Only check the engine stand if there is noise or excessive vibration when idling.
If the checks are correct, contact the Techline.

ALP8 Oil leaks from the turbocharger
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.
Check the area around the turbocharger
Note:
An oil leak does not correspond always to a fault of the turbocharger, the oil leak can arise from the area around
the turbocharger.
Depending on the vehicle type, the best visual access will be either from above or from below.
1. Do not start the engine.
Check the area around the turbocharger and identify the origin of the leaks.
Clean the oil traces on the turbocharger.
2. start the engine and let it warm up for several minutes.
IMPORTANT
If the air filter was previously removed, refit it before starting the engine (risk of aspirating foreign bodies into the
air inlet circuit).
Accelerate with no load several times, progressively increasing the duration before releasing the accelerator pedal.
Visually inspect the exterior condition of the fuel supply pipes and the turbocharger oil return and the area around it.
Identify the origin of the leaks.
Is an oil leak present at the air compressor inlet or outlet?
YESNO

CONTINUED 1
Check the air compressor inlet or outlet
Check for a loose interface (inlet or outlet) that is the cause of
the air leak.
Note:
It is normal to find oil traces inside the pipes at the turbocharger
inlet or outlet, because the air entering the compressor was
laden with oil from the engine rebreathing circuit.
Is the suspected interface properly tightened?Tighten the interface or the pipe
concerned.
end of the procedure
Replace the pipe concerned (see MR 364 (Mégane II) or 370 (Scénic II), Mechanical systems, 12B,
turbocharging).

Is an oil leak present only at the casing of the compressor section?
The turbocharger is not faulty. The oil leak is from another
engine component and the oil is flowing onto the turbocharger.
Is an oil leak present at the turbocharger oil supply inlet or outlet?
Check the turbocharger oil supply inlet and outlet
Check for a loose interface (inlet or outlet) that is the cause of
the oil leak.
Is the suspected interface properly tightened?Tighten the pipe concerned.
end of the procedure
Replace only the seal or the pipe of the section concerned (see
MR 364 (Megane II) or 370 (Scenic II), Mechanical, 12B,
Turbocharging).

Is an oil leak present at the interfaces of the turbine casing and the exhaust pipes?
End of procedure.
The turbocharger is not faulty. There is probably another fault in the engine.
Mark the component that is the source of the leak and refer to the repair manual (see MR 364 (Megane II) or 370
(Scenic II), 10A Engine and cylinder block assembly).

ALP9 Noise from the turbocharger
Apply Technical Note 5164A, Noise fault finding procedure.
Note:
Pay close attention to faulty components that might result in unjustified replacement of the turbocharger. For
example, whistling does not necessarily indicate damage to the turbocharger (this could be coming from the
exhaust, the timing, the gearbox, etc.).

ALP10 Exhaust fumes
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)

Recognition of parameters corresponding to the start of successful regenerations.
Make adjustments to align the parameter groups.
Group 1 Stored regeneration start no. 1 to 10
and
Group 2 Stored regeneration failure no. 1 to 10
For each group 1 parameter, if there is no parameter in group 2 in the next 30 miles (50 km), note that this means
a successful regeneration (R). If there is one, this means a failure (E).
