ALP 13 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 by running 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) or MR 370
(Scénic II), Mechanical, 13B, Diesel
injection, Rail pressure sensor:
Removal - Refitting).
Check the low pressure circuit by running TEST 1 Low pressure circuit check.
Check the injectors by running TEST 3 Injector check.
Visually check that there are no leaks on the high pressure circuit by running TEST 7 High pressure circuit
sealing check.
Check the air inlet circuit by running TEST 5 Inlet circuit check.

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 by running 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 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
