My 04 X5 3.0 has started to give me chimes and the distance til empty on the display at every start regardless of the amount of gas in the tank. I believe this should only happen when the tank is under 31 miles. I have 91K on the clock and there have been some odd electrical issues including dead battery. Any thoughts?
