Water in Fuel
Sometimes, water can be found in the fuel tank along with diesel fuel. This can happen if the service station does not regularly inspect and clean their fuel storage tanks or the fuel is contaminated as received from the service stations suppliers.
If water is detected by the Water in Fuel Sensor, a Water-In-Fuel light will illuminate. If the Water-In-Fuel light illuminates, the water must be drained from the fuel system on the vehicle.
