TEST 3 Low pressure circuit check
Check the fuel filter:
– Conformity of the fuel filter (correct part number and RENAULT filter),

– 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.

TEST 5 Air flowmeter
Impurities in the grilles:
Visual inspection: remove the flowmeter. There should be no foreign bodies on the grilles (see diagram 110734).
Do not clean the grilles using compressed air or any other procedure: this damages the sensors and
creates variations from the values displayed on the CLIP tool.
Check the sealing of the air circuit upstream of the air flowmeter:
disconnected or pierced pipes and air filter unit, seals present.
Replace the air flowmeter if necessary and clean upstream of this, if necessary.
Damage to electrical components:
Visual inspection:
– remove the flowmeter, the components should not be broken (see diagram no. 110736).
Replace the air flowmeter if necessary.
Oxidation of the electrical components:
Visual inspection:
– remove the air flowmeter, there must not be any green deposits on the electrical components.
Replace the air flowmeter if necessary.
Clogging of the air flowmeter:
Te s t :
– Check the values for conformity:
* During the first 5 seconds after starting:
– Coolant temperature: 80°C.
– Engine speed: at idle speed (750 rpm < PR055 < 850 rpm).
– Air flow measurement: 37 kg/h < PR132 < 57 kg/h.
– EGR valve OCR*: between - 10% and 0%.
* After the starting phase:
– Coolant temperature: 80°C,
– Engine speed: at idle speed (750 rpm < PR055 < 850 rpm).
– Air flow measurement: 25 kg/h < PR132 < 35 kg/h.
– EGR valve OCR*: between 10% and 40%.
– Refer to the interpretation of DF056 Air flow sensor circuit 2.DEF, for the air flowmeter checks.
Replace the air flowmeter if necessary.

Note: In certain cases, this procedure is to be carried out only after replacement of the particle filter or after an
After-sales regeneration of the particle filter.
– Start the engine.
– Raise the engine coolant temperature.
– Read the coolant temperature with PR064 Coolant temperature until a value greater than 65ºC is obtained.
– Accelerate the engine to 4000 rpm and maintain this speed for 5 minutes.
–After 5 minutes, release the accelerator and stop the engine.
– Switch on the ignition.
– Run command SC036 Reinitialise programming and select After particle filter replacement or After
particle filter regeneration (as appropriate).
– Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Communication
lost with computer: EDC16C36, check the tool connection and computer power supply.
–Then switch on the ignition again, clear the present or stored faults from the computer memory (operation
to be carried out within 3 minutes of switching on the ignition).

TEST 9 Incorrect injector operation
Section A: Fuel regulation balance check for each injector (individual correction):
– In the CLIP diagnostic tool, choose the Fuel circuit subfunction.
– With the engine idling and the fuel temperature > 50°C, display the flow correction values for each injector
(individual correction), i.e.:
– PR364 Cylinder no. 1 fuel flow correction.
– PR405 Cylinder no. 2 fuel flow correction.
– PR406 Cylinder no. 3 fuel flow correction.
– PR365 Cylinder no. 4 fuel flow correction.
The flow correction range per injector is between - 5 mg/stroke and + 5 mg/stroke without reaching these
values.
– If this has not already been carried out, check the injector connections and wiring.
– Check the connections and wiring of the engine management computer to the injectors.
– Repair if necessary.
– Check the IMA injector codes, comparing the IMA codes on the injectors (the IMA codes must be read from left
to right) and the IMA codes read in the CLIP diagnostic tool.
– If the IMA codes are correct, continue the fault finding procedure,
– If not, modify the incorrect IMA codes using command SC002 Enter injector codes (see Interpretation of
commands).
To confirm the repair, consult part B of test 9.
CASE No. 1: If at least one of these values is equal to or greater than + 5 mg/st
– Check the valve clearance.
– Check the condition of the engine and the compressions (using the Clip diagnostic tool or a compression
gauge).
– If the compression test reveals a cylinder fault, carry out the necessary repairs.
– If the compression is correct, check that the injector is fitted correctly (see MR 364 (Mégane II), 370 (Scénic II)
or 395 (Laguna II), Mechanical, 13B, Diesel injection, Diesel injector: Removal - Refitting)
In particular, check that each injector has one compression washer.
Check the fuel regulation again for each injector (individual correction).
– If not, replace the injector and check for the sealing washer. 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.
