4) The DTC "Fuel Level Too Low" is stored when there is/was too little fuel in fuel tank. The DTC is stored as a static
malfunction and is not switched to sporadic even if fuel tank has been filled with fuel (e.g. by the customer) in the meantime.
In this way, it can be determined that subsequent malfunctions were caused by lack of fuel, e.g. combustion misfires or
oxygen control related malfunctions.
