SYMPTOM	POSSIBLE CAUSES	ACTION
Engine cranks, but does not start	Low/contaminated fuel Air leakage Low-pressure fuel system fault Fuel pump driver module fault Blocked fuel filter Fuel volume regulator blocked/contaminated Fuel pressure control valve blocked/contaminated Fuel pump fault Crankshaft position sensor	Check the fuel level and condition. Check the low pressure fuel pump operation. Using the manufacturer approved diagnostic system, perform routine - Inline diagnostic unit 2 non-intrusive test - Low pressure fuel pump. 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 driver module 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 crankshaft position sensor circuits. Refer to the electrical guides
Difficult to start	Glow plug system fault (very cold conditions) Low/contaminated fuel Air leakage Fuel pump driver 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(s) fault	Check the glow plug circuits. Refer to the electrical guides. Check the fuel level/condition. Check the low pressure fuel pump operation. Using the manufacturer approved diagnostic system, perform routine - Inline diagnostic unit 2 non-intrusive test - Low pressure fuel pump. 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 driver module operation, check the low-pressure fuel system for leaks/damage.

Lack of power when accelerating	Intake air system fault Restricted exhaust system Low fuel pressure Exhaust gas recirculation valve(s) 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 the low pressure fuel pump operation. Using the manufacturer approved diagnostic system, perform routine - Inline diagnostic unit 2 non-intrusive test - Low pressure fuel pump. 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(s) fault	Check the intake air system for leaks. Check the fuel level/condition. Using the manufacturer approved diagnostic system, perform routine - Inline diagnostic unit 2 non-intrusive test - Low pressure fuel pump. 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. Check the low pressure fuel pump operation. Using the manufacturer approved diagnostic system, perform routine - Inline diagnostic unit 2 non-intrusive test - Low pressure fuel pump. 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
Engine cranks, but will not start in cold weather (below -15°C/5°F)	Fuel waxing/gelling in cold weather Fuel filter restricted or blocked by fuel solidification	NOTE: If the fuel filter requires replacement as a result of restrictions or blockages caused by fuel gelling or waxing as a result of cold weather extremes, the replacement filter will NOT be covered by warranty Check the fuel filter for restrictions/blockages. If evidence of fuel waxing/gelling is noted, first attempt to warm the vehicle/fuel system to minimum temperature of at least 3°C/38°F. It is recommended that the vehicle is brought into a garage or workshop to be allowed to warm up If evidence of fuel waxing/gelling is noted, the fuel filter should be replaced A Jaguar Land Rover approved diesel fuel additive should be added to the fuel (using the recommended dosage). Both the fuel and the additive should be at a minimum temperature of at least 3°C/38°F. Jaguar Land Rover Product Development, have validated the following BG products - DFC Plus High Pressure (HP) Extra Cold weather performance (BG Part no 23711)/DFC Plus HP Extra Cold weather performance with Cetane improver (BG Part no 23811) After the fuel additive has been introduced to the fuel, allow the vehicle to idle for a short time in order for the additive to mix thoroughly with the diesel fuel
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(s) fault	Check the low-pressure fuel system for leaks/damage. Check the low pressure fuel pump operation. Using the manufacturer approved diagnostic system, perform routine - Inline diagnostic unit 2 non-intrusive test - Low pressure fuel pump. 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
