Is the engine running on all cylinders?
NO
Check the operation of the injectors: apply test 8 Incorrect injector
operation.
If the fault is still present
Check the conformity of the accelerator pedal position sensor, the brake pedal sensor, the atmospheric pressure
sensor, the exhaust gas recirculation valve and the damper valve.
–Check the consistency of the signal: of the air flowmeter, of the engine coolant temperature sensor, of the fuel
temperature sensor and of the engine speed.
Check the connections, continuity and absence of interference resistance on the air flow sensor (apply DF056 Air
flow sensor circuit, 2.def), the engine coolant temperature sensor (apply DF001 Coolant circuit, 1.def), and the
engine speed (apply DF195 Camshaft sensor/engine speed consistency, 2.def).
Check: – That the diesel filter is not clogged (for the test, see DF053 Rail pressure regulation function
2.def).
–That there are no leaks on the high and low pressure diesel circuits: apply test 3 Turbocharged
air inlet circuit check.
–That the oil vapour rebreathing system is connected.
–The flow regulator (blocked/seized, apply the interpretation for command: AC011 Rail pressure
regulator).
–Check the timing setting (and the position of the high pressure pump sprocket) (see MR 364 (MEGANE II) or
370 (SCENIC II), Mechanical, 11A, Top and front of engine).
–Check the cylinder compressions (balance of the cylinder compressions with the Compression test function
on the CLIP Technic diagnostic tool).
–Measure the engine compressions using the special tool.
If the fault is still present, contact the Techline.YES

TEST8 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 of 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.
A flow correction value greater than or equal to 5 mg/st absolute value can indicate an injector fault or cylinder
sealing fault.
–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, change the incorrect IMA codes using command SC002 Enter injector codes (see Interpretation of
commands).
To confirm the repair, consult part B of this test.
CASE No. 1: If at least one of the values is greater than or equal to + 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 the fitting conformity of the injector (see MR 364 (Mégane II) or 370 (Scénic
II), 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.
CASE No. 2: If at least one of the values is less than or equal to - 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.

Weigh the diesel fuel and note the fuel weight after subtracting the weight of the empty plastic cup and its cover.
Does the fuel weight fall between the minimum and maximum weights given in the table below?

Check the fuel temperature by immersing a thermometer in the plastic cup.
YES NO
End of test. The fuel is not correct.
If the fuel weight is l ess than the minimum value then there is petrol in the diesel fuel.
If the fuel weight is greater than the maximum value then there is oil in the diesel fuel.
Drain the fuel circuit, including the tank (seeMR 364 (Mégane II)orMR 370 (Scénic
II), Mechanical, 19C, Tank, Draining the fuel tank).
