I. HAZARDS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to contamination. The risks associated with
contamination are:
–damage to or destruction of the high pressure injection system,
–components jamming,
–components losing seal integrity.
All After-Sales operations must be performed under very clean conditions. This means that no impurities
(particles a few microns in size) should have entered the system during dismantling.
The cleanliness principle must be applied from the filter to the injectors.
What are the sources of contamination?
–metal or plastic swarf,
–paint,
–fibres: from cardboard,
from brushes,
from paper,
from clothing,
from cloths.
–foreign bodies such as hair,
–ambient air
–etc.
II. ADVICE TO BE FOLLOWED BEFORE ANY OPERATION
Check that you have plugs for the unions to be opened (set of plugs available from the Parts Department). The plugs
are single-use only. After use, they must be discarded (once used they are soiled and cleaning is not sufficient to
make them reusable). Unused plugs must also be discarded.
Check that you have hermetically resealable plastic bags for storing removed parts. Parts stored in this way will be
less susceptible to the risk of contamination. The bags are single-use only. Once used, they must be thrown out.
Use lint-free cleaning cloths (cloth part reference 77 11 211 707). Using normal cloth or paper is prohibited. They are
not lint-free and could contaminate the fuel circuit. Each cloth should only be used once.
Use fresh cleaning agent for each operation (used cleaning agent is contaminated). Pour it into an uncontaminated
container.
For each operation, use a clean brush in good condition (the brush must not shed its bristles).
Use a brush and cleaning agent to clean the unions to be opened.IMPORTANT
Cleaning the engine using a high pressure washer is prohibited because of the risk of damaging connections. In
addition, moisture may collect in the connectors and create electrical connection faults.
IMPORTANT
Before any work is carried out on the high pressure injection system, protect:
–the accessories and timing belts,
–the electrical accessories, (starter, alternator, electric power-assisted steering pump),
–the flywheel surface, to prevent any diesel from running onto the clutch friction plate.

AFTER REPAIRDeal with any faults displayed by the diagnostic tool. Clear the computer fault
memory.
Carry out a road test followed by another check with the diagnostic tool.

Sensor electrical conformity
Test the air inlet circuit (from the air filter inlet to the inlet manifold tracts, run test 5 Inlet circuit check):
–air filter unit inlet not blocked and filter not clogged,
–oil vapour recirculation circuit connected correctly,
–low and high pressure air circuit sealed and not obstructed: ducts, mounting clamps present and tightened,
turbocharging pressure sensor fitted, exchanger, etc., run TEST 1 Low pressure circuit check and TEST 7
High pressure circuit sealing check
–check that the damper valve is not jammed closed.
Carry out the necessary repairs.
Check the electrical conformity of the air flowmeter:
Check the + 5 V supply of the air flowmeter on the following connection:
–3KJ of component 799.
Check the + 12 V after relay supply of the air flowmeter on the following connection:
–3FB (or 3FB3) of component 799.
Check the continuity and absence of interference resistance of the following connections:
–3DV,
–3DW, between components 120 and 799.
Flowmeter connected, vehicle ignition on and engine stopped:
Measure the voltage between connections 3DW and 3DV of component 799.
If the voltage is not between 0.3 V and 0.7 V, replace the air flowmeter, component code 799 (see MR 364 (Mégane
II), MR 370 (Scénic II), MR 385 (Modus), MR 392 (Clio III), MR 411 (New Twingo), MR 417 (Kangoo 2),

ALP18 Oil leaks from the turbocharger
NOTESBefore dealing with 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 turbocharger fault, 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 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?
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?Tighten the interface
or the concerned pipe.
End of procedure.
Replace the pipe concerned (see MR 364 (Mégane II), 370 (Scénic II), 392 (Clio III), 385 (Modus), 411
(New Twingo), or 417 (Kangoo II), Mechanical, 12B Turbocharging).
