Air flow requested and DF056 Air flow sensor circuit).
Check the coolant temperature sensor (refer to the interpretation of faults DF001 Coolant temperature sensor
circuit).
Check the turbocharging pressure (consult the interpretation of fault DF004 Turbocharging pressure sensor
circuit).
Check the low pressure fuel supply system by performing test 1 Low pressure supply check and test 2
Internal fuel transfer pump (ITP) check.
Check the high pressure fuel supply system by performing test 3 High pressure fuel pressure solenoid valve
check, test 4 High pressure pump (HPP) and fuel flow solenoid valve check and test 5 Rail high pressure
regulation circuit check.
Check the injectors by performing test 6 Major injector leak/injectors open and test 7 Incorrect injection
amount.

NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Is the vehicle equipped with a particle filter?
(Vdiag 45, 49 and 4D only)
NO
Check the engine oil grade and level.
Check the presence and conformity of the fuel, by running Test 13 Diesel fuel conformity check, and its circuit
(see MR 385, 392, 364, 370 or 417, Mechanical, 13A, Fuel supply).
Check the cooling system (see MR 385 392 364, 370 or 417 Mechanics, 19A, Cooling, Engine cooling system:
Specifications).
Check the fuel temperature sensor (refer to the interpretation of Fuel temperature sensor circuit faults DF098).
Check the coolant temperature sensor (refer to the interpretation of faults DF001 Coolant temperature sensor
circuit).
Check the air inlet circuit (refer to the interpretation of fault DF301 Air inlet circuit).
Check that the damper valve operates correctly (refer to the interpretation of fault DF641 Damper valve circuit).
Check the air flowmeter (refer to the interpretation of faults DF039 Inlet air temperature sensor circuit, DF129 Air
flow requested and DF056 Air flow sensor circuit).
Check the turbocharging pressure (consult the interpretation of fault DF004 Turbocharging pressure sensor circuit).
Check the preheating system (refer to the interpretation of fault DF025 Preheating unit diagnostic line).
Check the injection computer: that the connections and wiring are in good condition, that earths and feeds are present.
If the wiring is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring:
Precautions for repair), repair the wiring, otherwise replace it.
