Default MAF FAULT WHEN FUEL TANK NEARLY EMPTY

I drive my car every day, it's works perfectly (audi a8 d3 4.2i) but when my fuel tank is almost empty (50km range) i get the MASS AIR FLOW SENSOR FAULT CODE ( P0102 mass air flow circuit - g70 : low input, open circuit). after i refill the fuel tank, the fault is gone untill next time when i'm low on gas. does anyone encountered this problem? it's driving me nuts because my consumption is very high in that moment and the car rattle at idle, more than that, one time the engine shuts down when i started to drive backwards... if someoune could help me i thanks in advance. have a nice day!
