SYMPTOM	POSSIBLE CAUSES	ACTION
Engine cranks but does not start	Engine system fault Crash mode active Fuel level low Fuel contaminated Air ingress to fuel Low pressure fuel system restricted/leaking/damaged Fuel filter restricted/leaking/damaged	Using the Jaguar Land Rover approved diagnostic equipment, check the powertrain control module for related DTCs and refer to the relevant DTC index Using the Jaguar Land Rover approved diagnostic equipment, check the restraints control module for related DTCs and refer to the relevant DTC index Check the fuel level Check the fuel for contamination Check the low pressure fuel system for air ingress Check the low pressure fuel system for restrictions, leaks and damage Check the fuel filter for restrictions, leaks and damage

Rough idle	Engine system fault Air ingress to fuel Fuel level low Fuel contaminated Low pressure fuel system restricted/leaking/damaged Fuel filter restricted/leaking/damaged Exhaust gas recirculation system fault	Using the Jaguar Land Rover approved diagnostic equipment, check the powertrain control module for related DTCs and refer to the relevant DTC index Check the low pressure fuel system for air ingress Check the fuel level Check the fuel for contamination Check the low pressure fuel system for restrictions, leaks and damage Check the fuel filter for restrictions, leaks and damage Refer to the relevant article of the repair information and check the exhaust gas recirculation system
Lack of power when accelerating	Engine system fault Intake pipe restricted/blocked Exhaust system blocked Low pressure fuel system restricted/leaking/damaged Exhaust gas recirculation system fault	Using the Jaguar Land Rover approved diagnostic equipment, check the powertrain control module for related DTCs and refer to the relevant DTC index Check the intake pipe for restrictions and blockages Check the exhaust system for blockages Check the low pressure fuel system for restrictions, leaks and damage Refer to the relevant article of the repair information and check the exhaust gas recirculation system
Engine stops/stalls	Air ingress to fuel Fuel level low Fuel contaminated Low pressure fuel system restricted/leaking/damaged High pressure fuel system leaking Exhaust gas recirculation system fault	Check the low pressure fuel system for air ingress Check the fuel level Check the fuel for contamination Check the low pressure fuel system for restrictions, leaks and damage Check the high pressure fuel system for leaks Refer to the relevant article of the repair information and check the exhaust gas recirculation system
Engine judders	Fuel level low Fuel contaminated Air ingress to fuel Low pressure fuel system restricted/leaking/damaged High pressure fuel system leaking	Check the fuel level Check the fuel for contamination Check the low pressure fuel system for air ingress Check the low pressure fuel system for restrictions, leaks and damage Check the high pressure fuel system for leaks
Fuel consumption excessive	Low pressure fuel system restricted/leaking/damaged High pressure fuel system leaking Injector fault(s) Exhaust gas recirculation system fault	Check the low pressure fuel system for restrictions, leaks and damage Check the high pressure fuel system for leaks Using the Jaguar Land Rover approved diagnostic equipment, check the powertrain control module for related DTCs and refer to the relevant DTC index Refer to the relevant article of the repair information and check the exhaust gas recirculation system
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 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
Fuel gauge reading empty with fuel in the fuel tank	Active fuel level sensor circuit open circuit Passive fuel level sensor circuit open circuit Instrument cluster internal failure	Refer to the electrical circuit diagrams and check the active fuel level sensor circuit for open circuit, high resistance Refer to the electrical circuit diagrams and check the passive fuel level sensor circuit for open circuit, high resistance Using the Jaguar Land Rover approved diagnostic equipment, perform the guided diagnostic routine - Fuel Level Sensor Test
Fuel gauge not reading empty with no fuel in the fuel tank	Jet pump fault or fuel crossover tube blocked or leaking	Using the Jaguar Land Rover approved diagnostic equipment, check datalogger signals - Fuel Level Sensor Pump/Active/A (0xD908) - Fuel Level Sensor Eject/Passive/B (0xD907). If the right sensor reads empty when the left sensor reads more than empty, check that the jet pump is transferring fuel from the left side to the right side
