3/4 is as full as it gets!

I found the post I was thinking about. Here it is:

"Should the car still be under warranty I would suggest that you bring it to your closest Dealer. The malfunction that you describe may be as simple as just recalibrating the fuel level sensor. While this is simple for the Dealer or any Independent shop with a PIWIS or System2 tester it is not for the owner. There is a specific amount of fuel that is to be in the fuel tank for the calibration and the requirement of the tester. To have the proper amount of fuel in the tank requires the draining of it and then the adding of this specific amount. Even should the car require a new fuel level sender it would still require this calibration.
