TEST 10 Turbocharger air chain
Check for the presence of the 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 NO
Check the condition of the air filter
Visually inspect the condition of the filter section
of the air filter.
Is either 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
YESReplace the air filter (see MR 364
(Mégane II), 370 (Scénic II), 417
(Kangoo II), 385 (Modus), 392 (Clio III),
12A Fuel mixture, Air filter, removal -
refitting).
YESReplace any faulty parts (MR 364
(Mégane II), 370 (Scénic II), 417
(Kangoo II), 385 (Modus), 392 (Clio III),
12B Turbocharging).
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

WARNING
During this operation, it is essential to:
– refrain from smoking or bringing incandescent objects close to the work area,
– protect yourself against fuel splashes due to residual pressure in the pipes,
– wear safety goggles with side guards,
– wear leaktight gloves (Nitrile type).
IMPORTANT
– To avoid any corrosion or damage, protect the areas on which fuel is likely to run.
– To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components
exposed to the open air.
Preparations:
Weigh an empty 1300 ml plastic cup (part no. 77 11 171 413) with its cover (part no. 77 11 171 416) using
electronic scales such as those used in body paint workshops (example: PANDA part no. 77 11 224 995). Record
the weight of the empty plastic cup.
This type of plastic cup is used to prepare paint.
Take a 1 l fuel sample from the diesel fuel filter outlet (see MR 392 (Clio III), 364 (Mégane II ph2), and 417
(Kangoo II), Mechanical, 19C, Tank, Fuel tank: Draining, or MR 385 (Modus) and 370 (Scénic II ph2)
Mechanical, 19C, Tank, Draining the fuel tank), using a pneumatic transfer pump (part no. 634-200) and place
it in the 1300 ml plastic cup.
Cover the plastic cup with its cover and let the fuel settle for approximately 2 minutes.
Is the fuel cloudy or does it separate
into two parts?Presence of water in diesel fuel, the fuel is not compliant.
Drain the fuel circuit, including the tank (see MR 392 (Clio III),
364 (Mégane II ph2), and 417 (Kangoo II), Mechanical, 19C,
Tank, Fuel tank: Draining or MR 385 (Modus) and 370
(Scénic II ph2), Mechanical, 19C, Tank, Draining the fuel
tank).
