Hello, I have a 2004 Mini Cooper S and i have just recently changed all four of my brake pads and flushed out my brake fluid. New pads and brake fluid was in and when i started my car to brake in my pads, i found that my fuel gauge just moved a little notch so the needle will be noticeable. I knew that i have at least half a tank of gas in there, but i thought it would go up later since my car was slanted for awhile. A day has gone and it never went up at all. Anyone knows what happened or what can happen and how to fix it?
