Hi, I have a 2012 200 series diesel Landcruiser which has recently started giving me a 'Check Fuel System' warning along with an amber exclamation warning sign once the fuel level drops below 1/4 of a tank. It has nothing to do with fuel filters as it still occurs after the filters have been replaced. After I refuel the message disappears.
My mechanic suggested it could be the transfer pump in the fuel tank as he had seen this problem in Prados after around 160,000km. We replaced the pump but the problem is persisting. The issue first began at around 160,000km and the vehicle has now done 180,000km.
Has anyone else seen or heard of this issue? Suggestions would be gratefully received.
