Check the injectors while applying Test 6 Major leak in injectors/injectors open.
Apply Technical Note 5164A, Noise fault finding.
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.).
Contact the Techline if the customer complaint is still present.

ALP 19 Oil leak from the turbocharger
NOTESThis ALP concerns the following customer complaint:
– Oil leaks from the turbocharger.
Check the area around the turbocharger
Note:
An oil leak does not correspond always to a turbocharger fault, the oil leak can arise from the area around the
turbocharger.
According to the vehicle type, maximum visual access will either be 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 removed previously, refit it before starting the engine (risks foreign matter entering 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?
YES
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 is laden with oil
from the
engine rebreathing circuit.
Is the suspected interface properly tightened?
YES
Replace the pipe concerned (see MR 364 (Mégane II), 370 (Scénic II), 417 (Kangoo II), 385 (Modus), 392 (Clio
III), Mechanical, 12B, turbocharging).
NO
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

Is an oil leak present only at the casing of the compressor section?
YES NO
The turbocharger is not faulty. The oil leak is
from another engine component and the oil is
flowing onto the turbocharger.

CONTINUED 2
Is an oil leak present at the turbocharger oil supply inlet or outlet?
YESNO
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?
YES
Only replace the seal or pipe of the part concerned (see MR 364 (Mégane II), 370 (Scénic II), 417
(Kangoo II), 385 (Modus), 392 (Clio III), Mechanical, 12B, turbocharging).
Is an oil leak present at the interfaces of the turbine casing and the exhaust pipes?
YES
The turbocharger is not faulty. There is probably another fault in the engine.
Mark the component from which arises the leak and refer to the repair manual (see MR 364 (Mégane II), 370
(Scénic II), 417 (Kangoo II), 385 (Modus), 392 (Clio III), 10A Engine and Peripherals).

ALP 20 Exhaust fumes
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Is the vehicle equipped with a particle filter?
(Vdiag 45, 49 and 4D only)
NO
Check the engine oil grade and level.
Check the presence and conformity of the fuel, by running Test 13 Diesel fuel conformity check, and its circuit
(see MR 385, 392, 364, 370 or 417, Mechanical, 13A, Fuel supply).
Check the cooling system (see MR 385 392 364, 370 or 417 Mechanics, 19A, Cooling, Engine cooling system:
Specifications).
Check the fuel temperature sensor (refer to the interpretation of Fuel temperature sensor circuit faults DF098).
Check the coolant temperature sensor (refer to the interpretation of faults DF001 Coolant temperature sensor
circuit).
Check the air inlet circuit (refer to the interpretation of fault DF301 Air inlet circuit).
Check that the damper valve operates correctly (refer to the interpretation of fault DF641 Damper valve circuit).
Check the air flowmeter (refer to the interpretation of faults DF039 Inlet air temperature sensor circuit, DF129 Air
flow requested and DF056 Air flow sensor circuit).
Check the turbocharging pressure (consult the interpretation of fault DF004 Turbocharging pressure sensor circuit).
Check the preheating system (refer to the interpretation of fault DF025 Preheating unit diagnostic line).
Check the injection computer: that the connections and wiring are in good condition, that earths and feeds are present.
If the wiring is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring:
Precautions for repair), repair the wiring, otherwise replace it.
