WARNING: This page is about a different variant/trim than selected.

SYMPTOM	POSSIBLE CAUSES	ACTION
Engine cranks, but does not start	Inertia fuel shut off switch Low/Contaminated fuel Air leakage Low-pressure fuel system fault Fuel pump module fault Blocked fuel filter Fuel volume regulator blocked/contaminated Fuel pressure control valve blocked/contaminated Fuel pump fault Crankshaft Position Sensor (CKP)	Check that the inertia switch has not tripped. Check the fuel level and condition. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the intake air system for leaks. Check the fuel pump operation, check the low-pressure fuel system for leaks/damage. Check the fuel filter, check for DTC s indicating a fuel volume or pressure control valve fault. Check the fuel pump. Check the CKP circuits. Refer to the electrical guides.
Difficult to start	Glow plug system fault (very cold conditions) Low/Contaminated fuel Air leakage Fuel pump module fault Low-pressure fuel system fault Blocked fuel filter Fuel volume control valve blocked/contaminated Fuel pressure control valve blocked/contaminated Exhaust gas recirculation valve fault	Check the glow plug circuits. Refer to the electrical guides. Check the fuel level/condition. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the intake air system for leaks. Check the fuel pump operation, check the low-pressure fuel system for leaks/damage. Check the fuel filter, check for DTC s indicating a fuel volume or pressure control valve fault. Check the exhaust gas recirculation system.
Rough idle	Intake air system fault Low/Contaminated fuel Low-pressure fuel system fault Blocked fuel filter Fuel volume control valve blocked/contaminated Fuel pressure control valve blocked/contaminated Exhaust gas recirculation valve fault	Check the intake air system for leaks. Check the fuel level/condition. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the low-pressure fuel system for leaks/damage. Check the fuel filter, check for DTC s indicating a fuel volume or pressure control valve fault. Check the exhaust gas recirculation system.
Lack of power when accelerating	Intake air system fault Restricted exhaust system Low fuel pressure Exhaust gas recirculation valve fault Turbocharger actuator fault	Check the intake air system for leakage or restriction. Check for a blockage/restriction in the exhaust system, install new components as necessary. Check for DTC s indicating a fuel pressure fault. Check the exhaust gas recirculation system. Check turbocharger actuator.
Engine stops/stalls	Air leakage Low/Contaminated fuel Low-pressure fuel system fault High pressure fuel leak Fuel volume control valve blocked/contaminated Fuel pressure control valve blocked/contaminated Exhaust gas recirculation valve fault	Check the intake air system for leaks. Check the fuel level/condition. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the fuel system for leaks/damage: Check for DTC s indicating a fuel volume or pressure control valve fault. Check the exhaust gas recirculation system.
Engine judders	Low/Contaminated fuel Air ingress Low-pressure fuel system fault Fuel metering valve blocked/contaminated Fuel volume control valve blocked/contaminated Fuel pressure control valve blocked/contaminated High pressure fuel leak Fuel pump fault	Check the fuel level/condition. Draw off approximately 1 ltr (2.11 pints) of fuel and allow to stand for 1 minute. Check to make sure there is no separation of the fuel indicating water or other liquid in the fuel. Check the intake air system for leaks. Check the low-pressure fuel system for leaks/damage. Check the high pressure fuel system for leaks, check for DTC s indicating a fuel volume or pressure control valve fault. Check the fuel pump.
Excessive fuel consumption	Low-pressure fuel system fault Fuel volume control valve blocked/contaminated Fuel pressure control valve blocked/contaminated Fuel temperature sensor leak High pressure fuel leak Injector(s) fault Exhaust gas recirculation valve fault	Check the low-pressure fuel system for leaks/damage. Check for DTC s indicating a fuel volume or pressure control valve fault. Check the fuel temperature sensor, fuel pump, etc for leaks. Check for injector DTC s. Check the exhaust gas recirculation system.
