Does anyone know what causes this? I have the low fuel light blinking on my 2005 Coupe in the same manner you have but no check engine light. I'm driving along and all the sudden it comes on and flashes for a few minutes then goes out. The tank is full of gas at this time. It's happened 5 times in the last month and I've had it in and out of the dealer each time. They are telling me there is nothing wrong and obviously there is. Help??
