Jaguar XF coolant level warning light issue despite adequate coolant level on Jaguar XF

Some Jaguar XF owners report experiencing coolant level warning light issues despite having adequate coolant levels. These problems may stem from a faulty float sensor in the expansion tank, which can trigger intermittent low coolant warnings even when the tank is full. Additionally, a malfunctioning coolant level sensor float may cause the warning light to activate occasionally, but this can often be resolved with a simple replacement. Other potential causes include degeneration of the plastic coolant bottle, loss of pressure in the radiator cap, water loss through vaporization, broken water hoses, or a leaking water pump. To address these issues, owners are advised to check the float sensor for faults, consider replacing the sensor float for accurate readings, and inspect the coolant bottle, radiator cap, hoses, and water pump for any signs of damage or leaks.
