WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

SYMPTOM	POSSIBLE CAUSES	ACTION
Engine cranks, but does not fire	Positive crankcase ventilation system blocked/leaking Engine system fault	Check the integrity of the positive crankcase ventilation system. Rectify as necessary Using the Jaguar Land Rover approved diagnostic equipment, check the powertrain control module for related DTCs and refer to the relevant DTC index
Engine cranks and fires, but will not start	Evaporative emissions system fault Engine system fault	Refer to the relevant service information and check the purge valve Using the Jaguar Land Rover approved diagnostic equipment, check the powertrain control module for related DTCs and refer to the relevant DTC index
Difficult cold start	Engine coolant level/anti-freeze content Battery/charging system fault Engine system fault Evaporative emissions system fault	Check the engine coolant level and condition. Rectify as necessary Refer to the relevant service information and check the battery and charging system. Rectify as necessary 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 service information and check the evaporative emissions system. Rectify as necessary
Difficult hot start	Fuel injector leaking Engine system fault Evaporative emissions system fault	Check the fuel injectors for leaks. Rectify as necessary 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 service information and check the evaporative emissions system. Rectify as necessary
Difficult to start after hot soak (vehicle standing, engine off, after engine has reached operating temperature)	Fuel injector leaking Engine system fault Evaporative emissions system fault	Check the fuel injectors for leaks. Rectify as necessary 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 service information and check the evaporative emissions system. Rectify as necessary
Engine stalls soon after start	Positive crankcase ventilation system blocked/leaking Engine system fault Intake air system leaking/restricted	Check the integrity of the positive crankcase ventilation system. Rectify as necessary 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 air system for leaks and restrictions. Rectify as necessary
Engine hesitates/poor acceleration	Fuel injector leaking Engine system fault Transmission system fault Intake air system leaking/restricted Accelerator pedal movement restricted (carpet, mats, etc)	Check the fuel injectors for leaks. Rectify as necessary 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 transmission control module for related DTCs and refer to the relevant DTC index Check the intake air system for leaks and restrictions. Rectify as necessary Check that the accelerator pedal is free from restriction. Rectify as necessary
