The gas gauge in my audi just kinda stopped working.
By kinda, I mean that, before when I would fill up gas all the way, the gauge would sit really close to the F mark.
Now, whenever I fill up and the gas pump automatically clicks and shuts off, whenever I start the car, the gauge only goes up the 3/4, sometimes less.
I tried filling up again, but it just starts overflowing.
Whenever the gas light comes on, I pump gas and it only costs me about $20, when I know it should cost more.
Let's assume it's the gas gauge sensor, since I'm not sure what else it could be.
QUESTION
If the gauge is malfunctioning or not working properly, does that affect the gas pump from "knowing" when to stop pumping gas or how does that work??
And if my gas light is coming on, could it be possible that if the sensor is malfunctioning, that I actually do have more gas than indicated, just that the sensor is broken??
