ALP 8 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.
According to the vehicle type, maximum visual access will either be 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 for 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?
YES NO
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 traces of oil inside the pipes at the
turbocharger inlet or outlet as the air passing into the
compressor is laden with oil from the engine rebreathing circuit.
Is the suspected interface properly tightened?
YES
Replace the pipe concerned (see MR 364 (Mégane II), 370 (Scénic II) or 395 (Laguna II), Mechanical, 12B,
Turbocharging).
NOTighten the interface or the
concerned pipe.
End of procedure.

TEST 3 Low pressure circuit check
Check the fuel filter:
– Conformity of the fuel filter (correct part number and RENAULT filter),
– Positioning and clogging condition of the filter cartridge,
– Positioning and condition of the seals.
If there is metal swarf in the filter:
Replace the fuel filter, bleed the circuit and continue the fault finding procedure.
Supplying the injection system with fuel from an additional tank.
This operation aims to detect possible faults in the low pressure supply system of a vehicle by replacing it entirely
with an additional tank.
Mode:
– Disconnect the diesel fuel supply pipe at the fuel filter inlet and seal it with a plug.
– Connect a tube to the fuel filter inlet and insert the other end into a clean container which is approximately
5 litres in volume.
– Disconnect the diesel fuel return pipe at the pump return and injector return joint and seal it with a plug.
– Fill the container with clean diesel fuel.
– Start the engine and let the system drain itself of its air (there must not be any air bubbles in the return pipe).
Is the customer complaint still present?
NO
YES
Are the low pressure circuit connections in order
and in good condition?
YES NO
If the low pressure circuit is in order, reconnect the various
pipes making up the low pressure circuit and repeat the
fault finding procedure in the fault finding chart or for the
fault that referred you to this test.
Carry out the necessary repairs.
