This signal serves as supplemental information for the ME control unit for detection of combustion misfires through fuel starvation.

The information about the fuel level is transferred to the instrument cluster via CAN. From there, the information reaches the ME-SFI [ME] control unit via CAN.

If the fuel reserve warning light is flashing, the purge system has a gross leak (tank lid missing).

If the fuel tank is filled to less than approx. 1/4 or to more than 3/4, the leak test of the fuel system is suppressed. A test for major leakage is still performed.
