Check the condition of the air filter
Visually inspect the condition of the filtering section of the air
filter.
Is the air filter or its seal damaged?
Is the air filter fouled (does it contain a lot of impurities)?Replace the air filter (see MR 364
(Mégane II), 370 (Scénic II), 392
(Clio III), 385 (Modus), 411
(New Twingo) or 417 (Kangoo II)

Air filter, Removal - Refitting).
Low 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:
–fresh air inlet scoop on the front panel of the vehicle,
–air inlet pipe to the air filter,
–air pipe of the filter up to the compressor inlet,
–air flowmeter mountings.
Is one of these components incorrect (pipes dislodged,
torn, bent, pierced or kinked)?Replace the faulty parts (see MR
364 (Mégane II), 370 (Scénic II)
392 (Clio III), 385 (Modus), 411

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:
–compressor outlet pipe to the turbocharging air cooler (on some engines,
the turbocharging air cooler does not exist),
–outlet pipe of the turbocharging air cooler to the inlet manifold,
–inlet manifold,
–pressure and temperature sensors.
Is one of these components incorrect (pipes dislodged, torn, bent,
pierced or kinked)?Replace the faulty
parts (see MR 364

Exhaust circuit 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,
–pressure and temperature sensors connected.
Do certain of these components have blackish or whitish traces?
Run test 10 Turbocharger solenoid valve check.
