My gas gauge and water temperature gauge do not work when the car is cold.
I took the car to FL, 2500 miles in 4 days. Gas mileage was 27.5MPG with the cruise set at 77MPH.
Pick up is very good. Transmisson downshift on the automatic is very sweet. The BMW engineers knew what they were doing with that 'button' under the gas pedal.

I suspect corrosion or slightly loose electrical contacts at the fuse or some such. Disconnect and reconnect to see if it improves.
