Visually check the condition of the engine wiring harness.
Is the clutch clearance set correctly? Carry out the necessary repairs.
Check that the engine has not sucked up its oil (engine racing).
Is the compression in order? Carry out the necessary repairs.
Check that the turbocharger is working properly.
Run TEST 11 Air line at the turbocharger.

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).
