ALP 4 Poor performance
NOTESBefore dealing with 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.
IMPORTANT
In the event of the engine overheating above 11 0 ° C, the computer deliberately limits the fuel flow, and supplies
the fan assembly until the battery is completely discharged.
Is the poor performance accompanied by smoke?
YES
Check:
– That the EGR valve is not jammed in the open position.
– That the injectors are properly mounted (presence and conformity of the sealing washer).
Is the engine running on all cylinders?
NO
Check that the injectors are operating correctly. (See Test 1)
If the fault is still present
Check the conformity of the accelerator pedal position sensor, the brake pedal sensor, the atmospheric pressure
sensor and the EGR valve.
– Check the condition of the air filter.
– Check the consistency of the signal: from the flow sensor or the pressure/air temperature sensor, engine coolant
temperature sensor, fuel temperature sensor, engine speed.
No foreign bodies on the flowmeter grille (visual inspection only).
Check:
– That the diesel filter is not clogged.
– That there are no leaks in the low pressure and high pressure diesel circuits;
– that the air inlet circuit is complete (sealed and not obstructed),
– That the oil vapour rebreathing system is connected.
– The flow regulator (jammed/seized, consult the interpretation of command AC011 Rail pressure
regulator).
– The turbocharger control (jammed / seized), consult the interpretation of command
AC004Turbocharging solenoid valve,
– Check the engine compressions (cylinder compression balance with the Compression test function on
the CLIP tool).
– Check that the exhaust pipe is not blocked.
NO
YES
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

TEST 1 Injector test
Part 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 normal 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, by comparing the IMA engraved codes on the injectors (the IMA codes are read
from left to right) and the IMA codes read with 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 this test.
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 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).
–Run Part B of this test to confirm the fault finding procedure.
CASE no. 2: If at least one of these values is less than or equal to - 5 mg/stroke
– 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).
–Run Part B of this test to confirm the fault finding procedure.

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.
End of test.The fuel is not correct.
If the fuel weight is less 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 (see MR 364 (Mégane) or
370 (Scénic), Mechanical, 19C, Tank, Fuel Tank: Draining).
Note:
If the weight measured reaches the limit values, the measurement can be performed with a 2230 ml (part no. 77
11 171 414) plastic cup with a cover (part no. 77 11 171 417):
– Carry out a quick test drive in order to mix the fuel, then remove 2 l of fuel.
– Perform the test again and check the results by multiplying the limit values by 2.
