In this case, it may be the solenoid valve dynamic specification which is at fault (atmospheric pressure
resetting time). Final fault finding is carried out by measuring this specification on a special bench.

NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
Check that solenoid valve casing does not have any splashes of fluid on it which may impede the breather (water,
engine oil, gearbox oil, brake fluid, coolant, mud, dust, or any other substance).
Instructions:
–The solenoid valve must be set up 450 mm above the ground, in an area free from water, mud, or any other fluid.
–Cleaning with a high pressure jet is forbidden.
Is there coolant present? Follow the recommendations below.
Is the solenoid valve subjected to significant fluctuations
or impacts?
Instructions:
–The solenoid valve must be correctly secured to its
mounting.
Contact with the engine environment is forbidden.Follow the recommendations below.
Check the turbocharger regulation control (no partial jamming, etc.).
Does the turbocharger control work? Carry out the necessary repairs.
Replace the solenoid valve.
If the fault is still present, contact the Techline.

ALP13 Excessive consumption
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.

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: run 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 ΩΩ Ω 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.
Check the air inlet circuit: run TEST 5 Air inlet circuit check.
