NOTESSpecial note:
Only consult this customer complaint after a full check with the diagnostic tool.
See Feature, Function: Fuel supply management (timing, flow rate and pressure),
Flow capacity function (VLC) section.
Check that the fuel tank is correctly filled and that the fuel is correct: run TEST 13 Diesel fuel conformity check.
Check the low pressure circuit: run TEST 1 Low pressure circuit check.
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.
Is the engine wiring harness cut or pinched? Carry out the necessary repairs.
Is the compression in order? Carry out the necessary repairs.
Is the valve clearance set correctly? Carry out the necessary repairs.

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. Check the high pressure pump: run TEST 6
High pressure system check.
Is the "Flow capacity function"
programming active?
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?
Contact the Techline if the customer complaint
is still present.
Replace the diesel filter (see MR 364 (Mégane II),
MR 370 (Scénic II), MR 385 (Modus), MR 392
(Clio III), MR 411 (New Twingo), MR 417
(Kangoo 2), Mechanical, 13A, Fuel mixture, Fuel
filter: Removal - Refitting).
Contact the Techline if the customer complaint is still
present.

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: run 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),
MR 370 (Scénic II), MR 385
(Modus), MR 392 (Clio III), MR 411
(New Twingo), MR 417 (Kangoo 2),
Mechanical, 13B, Diesel injection,
Rail pressure sensor: Removal -
Refitting).
Check the low pressure circuit: run TEST 1 Low pressure circuit check.
Visually check that there are no leaks on the high pressure circuit: run TEST 7 High pressure circuit
sealing check.
Check the air inlet circuit: run TEST 5 Air inlet circuit check.
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.
