My 2015 XF 2.2 diesel runs out of fuel without warnings ,with the gauge reading 1/4 tank remaining and 165 to175 km range. This has happened 3 times this year. Keeping the fuel above that level there is no problem, any ideas my local jag outlet admitted they have no idea ! They replaced the pump the first failure . To get started after the breakdown I put 5 litres of diesel and it starts , when fill the tank after the breakdown it takes a max of 45 litres! Anyone have a clue?
