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
Replace only the seal or the pipe of the section concerned (see MR 364 (Mégane II) or 370 (Scénic II),
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. Another engine fault is probably present.
Mark the component that is the source of the leak and refer to the repair manual (see MR 364 (Mégane II)
or 370 (Scénic II), 10A Engine and peripherals).
NORetighten or the pipe concerned.
End of procedure.
NO
End of procedure.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

TEST 2 Turbocharger air chain
Check for an air filter.
Check the replacement frequency for the air filter in the Maintenance Booklet.
Compare the part numbers of the air filter fitted to the vehicle and that of the air filter recommended by the
manufacturer.
Check the air filter direction of fitting.
Is the air filter fitted to the vehicle correct?
YES
Check the condition of the air filter.
Visually inspect the condition of the filter section of
the air filter.
Is the air filter or its seal damaged?
Is the air filter clogged (does it contain a lot of
impurities)?
NO
Low pressure circuit check
Note:
According to the vehicle type, maximum visual
access will either be from above or from below.
Visually inspect the condition of the following
components:
– fresh air inlet scoop on the front end panel of the
vehicle,
– air filter air inlet pipe,
– filter air pipe up to the compressor inlet,
– air flowmeter mountings.
Is one of these components incorrect
(disconnected, cut, bent, pierced or kinked
pipes)?
NO
NO
YES
Replace the air filter (see MR 364 (Mégane II)
or 370 (Scénic II), Mechanical, 12A, Fuel
mixture,
Air filter,
Removal - Refitting
).
YESReplace the defective parts (see MR 364
(Mégane II) or 370 (Scénic II), Mechanical,
12B, Turbocharging).

TEST 2
CONTINUED
High pressure circuit check
Note:
According to the vehicle type, maximum visual
access will either be from above or from below.
Visually inspect the condition of the following
components:
– outlet pipe of the compressor to the turbocharging
air cooler,
– turbocharging air cooler outlet pipe at inlet
manifold,
– inlet manifold,
– temperature and pressure sensors.
Is one of these components incorrect
(disconnected, cut, bent, pierced or kinked
pipes)?
NO
Exhaust system check
Visually inspect the condition of the following
engine parts:
– the exhaust manifold circuit to the turbocharger
turbine,
– 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?
NO
Run test 3: Turbocharger control solenoid valve check.
YESReplace the defective parts (see MR
364 (Mégane II) or 370 (Scénic II),
Mechanical, 12B, Turbocharging).
YES
