Check the high pressure pump by running
TEST 6 High pressure system check.The vehicle has entered the "Flow capacity
function" program. This function is activated more
easily when: the external temperature is high, the
fuel level in the tank is at 1/4, the vehicle is laden
and if the vehicle speed is high. Is the "Flow capacity function"
programming active (ET563)?
Check the computer:
Check that the computer connectors are
properly locked.
Check the condition of the computer
connections (bent pin, signs of corrosion,
silicone, etc.).
If the connector(s) is faulty and if there is a
repair procedure (see Technical Note 6015A,
Repairing electrical wiring, Wiring:
Precautions for repair), repair the connector,
otherwise replace the wiring.Check the diesel filter.
Has the diesel fuel filter reached its full mileage?
Replace the diesel filter (see MR 364 (Mégane II)
or MR 370 (Scénic II), Mechanical, 13A, Fuel
supply, Fuel filter: Removal - Refitting).
Contact the Techline if the customer complaint is
still present.

OCR*: opening cyclic ratio
ALP11 Loss of power
NOTESSpecial note:
Only consult this customer complaint after a full check with the diagnostic tool.
See explanation for flow capacity function in system operation.
In this case, the lack of power is due to insufficient vacuum for the OCR * setpoint given.
Is the "Flow capacity function" programming
active (ET563)?Check the diesel filter.
Is it close to the replacement mileage?
Using the diagnostic tool, check that the injector
codes (C2I) are correctly entered on the identification
screen. If not, configure the correct injector codes
using command SC002 Enter injector codes.Replace the diesel filter (see MR 364
(Mégane II) or MR 370 (Scénic II),
Mechanical, 13A, Fuel supply, Fuel filter:
Removal - Refitting).
Check the air inlet circuit by running TEST 5 Inlet
circuit check.
Is the engine oil level correct? Top up the oil level.
Is the catalytic converter clogged or damaged?Replace the catalytic converter (see MR
364 (Mégane II) or MR 370 (Scénic II),

NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
Check that the fuel tank is correctly filled and that the fuel is correct by running TEST 13 Diesel fuel conformity
check.
Check the levels of engine oil and coolant.
Is the fuel temperature sensor leaking?Replace the fuel temperature sensor
(see MR 364 (Mégane II) or MR 370
(Scénic II), Mechanical, 13B, Diesel
injection, Rail pressure sensor:
Removal - Refitting).
Check the low pressure circuit by running TEST 1 Low pressure circuit check.
Check the injectors by running TEST 3 Injector check.
Visually check that there are no leaks on the high pressure circuit by running TEST 7 High pressure circuit
sealing check.
Check the air inlet circuit by running TEST 5 Inlet circuit check.

ALP16 Engine rattling, noisy engine, turbocharger noise
NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
If the noise arises from the turbocharger, apply Technical Note 5164A, Noise fault finding.
Note:
Pay close attention to faulty components that might result in unjustified replacement of the turbocharger. For
example, whistling does not necessarily indicate damage to the turbocharger (this could be coming from the
exhaust, the timing, the gearbox, etc.).
Check that the fuel tank is correctly filled and that the fuel is correct by running TEST 13 Diesel fuel conformity
check.
Check the levels of engine oil and coolant.
Is the compression in order? Carry out the necessary repairs.
Check the electrical conformity of the heater plugs (the resistance value of the heater plug must be less than 2 Ω).
Using the diagnostic tool, check that the injector codes (C2I) are correctly entered on the identification screen. If
not, configure the correct injector codes using command SC002 Enter injector codes

ALP18 Oil leaks from the turbocharger
NOTESBefore analysing 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 fault of the turbocharger, 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 for several minutes.
IMPORTANT
If the air filter was previously removed, refit it before starting the engine (risk of aspirating foreign bodies into 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?

YESNO
