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 was laden with oil from the
engine rebreathing circuit.
Is the suspected interface properly tightened?Tighten the interface or
the pipe concerned.
End of procedure.
Replace the pipe concerned (see MR 385, Mechanical, 12B, Turbocharging).

Is an oil leak present only at the casing of the compressor section?
The turbocharger is not faulty. The oil leak is from another engine component and the oil is flowing
onto the turbocharger.
End of procedure.
Is an oil leak present at the turbocharger oil supply inlet or outlet?
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?Tighten the pipe concerned.
End of procedure.
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?
The turbocharger is not faulty. There is probably another fault in
the engine.
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).End of procedure.
