Is an oil leak present at the turbocharger oil supply inlet or outlet?
YESNO
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?
YES
Only replace the seal or pipe of the part concerned (see MR 364 (Mégane II), 370 (Scénic II), 417
(Kangoo II), 385 (Modus), 392 (Clio III), Mechanical, 12B, turbocharging).
Is an oil leak present at the interfaces of the turbine casing and the exhaust pipes?
YES
The turbocharger is not faulty. There is probably another fault in the engine.
Mark the component from which arises the leak and refer to the repair manual (see MR 364 (Mégane II), 370
(Scénic II), 417 (Kangoo II), 385 (Modus), 392 (Clio III), 10A Engine and Peripherals).

Restore parameters PR063 Fuel temperature and PR064 Coolant temperature.
Fuel temperature reference value when operating at idle speed is between 60 °C and 80 °C.
The coolant temperature reference value is between 80 °C and 90 °C.
Note:
– when the fuel temperature is above 120°C, the maximum rail pressure is reduced to protect the plastic pipes,
– when the coolant temperature is above 100°C, the maximum rail pressure is reduced to protect the engine.
Are the fuel and coolant temperatures within the
reference value range?
YES
NOCheck the coolant temperature (see the
interpretation of DF001 Coolant
temperature sensor circuit) and fuel
temperature sensors (see the
interpretation of DF098 Fuel temperature
sensor circuit).

Start the engine and let it idle.
An unusual combustion noise may be heard.
Check the rail pressure using parameter PR038
Rail pressure.
At idle speed: rail pressure between 190 and
210 bar
2000 rpm: rail pressure between 440 and
560 bar
3000 rpm: rail pressure between 380 and
480 bar
4000 rpm: rail pressure between 470 and
570 bar
Are the rail pressure values correct?
NO
Replace the pump (see Replacement of
components).
Note:
Deviations from the reference values may occur in the rail pressure regulation circuit because of wear, clogging or
faulty sensors or actuators.
These deviations can only be compensated for by the pressure regulator within certain limits.
One consequence of this is that the rail pressure may be regulated so that it is too low or too high or it fluctuates.
YESRail pressure regulation circuit correct.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
