Is an oil leak present only at the casing of the compressor section?
YES NO
The turbocharger is not faulty. The oil leak is from another engine
component and the oil is flowing onto the turbocharger.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

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
Replace only the seal or the pipe of the section concerned (see MR 364 (Mégane II), 370 (Scénic II) or
395 (Laguna II), Mechanical, 12B, Turbocharging).
Is an oil leak present at the interfaces of the turbine casing and the exhaust pipes?
YES NO
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), 370
(Scénic II) or 395 (Laguna II), 10A Engine and peripherals).
NO
Tighten the pipe concerned.

CASE No. 2: If at least one of these values is equal to or less than - 5 mg/st
– Check the valve clearance.
– Check the level and condition of the engine oil.
– Remove the injector with the largest correction.
– If there is diesel fuel contamination, check the condition of the cylinder concerned (cylinder, piston, valves).
Use an endoscope if possible.
– Only replace the removed injector, and modify the IMA code using command SC002 Enter injector codes
(see Interpretation of commands).
–Apply Part B of this test to confirm the fault finding.
CASE No. 3: If at least one of these values does not stabilise (20 seconds after starting)
– Check the low pressure circuit using Test 4 Low pressure circuit check.
– Check the conformity of the fuel by applying Test 11 Diesel fuel conformity check.
–Apply Part B of this test to confirm the fault finding procedure
CASE No. 4: If all the fuel flow correction values are correct (between - 5 mg/st and + 5 mg/st)
–Apply Part C of this test (Fuel return flow measurement).
IMPORTANT
When removing or refitting injectors, follow the cleanliness and safety instructions (see MR 364 (Mégane II), 370
(Scénic II) or 395 (Laguna II), Mechanical, 13B, Diesel injection, Diesel injector: Removal - Refitting).

TEST 10 Temperature upstream of turbine too low
Run full fault finding on the injection computer using the
diagnostic tool.
Are any faults present or stored?
NO
Apply Test 1 Exhaust system check.
Is the exhaust pipe in order?
YES
Apply Test 4 Turbocharged air inlet circuit check.
Is the inlet circuit in order?
YES
Apply Test 5 Air flowmeter.
Is the air flow sensor correct?
YES
Apply Test 9 Poor injector operation.
Are the injectors correct?
YES
Contact the Techline.YES
Apply the procedure for
dealing with the associated
faults (see Interpretation of
faults).
NO
Repair then carry out a
new particle filter
regeneration.
Run command SC017
Particle filter
regeneration.
If the second regeneration
is successful, it is essential
to change the engine oil
and replace the oil filter.
If the second regeneration
fails, contact the Techline.
