The light on my gear shift is not turning off and my the car is slow to turn over (even after 45 min of the car being off). I had read about the 15 min delay for the electrical system, but the light on the gear shift was still on when I got up this morning (after 16hrs of the car being off and parked). Is this an indicator of a larger electrical problem? This is a 740i that is 10 yrs old with only 70k miles; the inspection is due.
