Sounds like it could be a sending unit issue. Were you at 1/4 tank when you filled up?

i was on empty. it gradually went up to full tank over 30 minutes of driving but the range still says zero

did you fill it with water?

I'm guessing that the fuel level sensor is going a bit haywire. Have you ever run fuel cleaner through the gas tank? Do you use premium fuel?

BMW has been having a very similar problem and the issue is that something in the fuel coats the sensor over time, and using a fuel cleaner such as Redline SC-1, BMW Fuel Cleaner or Techron will clean most of it off and fix it. -> This was issued to dealers after quite a few decided to replace the whole darn fuel sending unit that cost BMW upwards of 2K in warranty work per car!

inside your fuel thank have a floater, it is damage or is worn. replace with new unit as directed.
