Altitude Changes
 

I live at 3000'

When I fuel up to high in the Fuel neck,my Overhead read-out will say 999 km for about 100-120 km,then start to drop.

When I take a trip to the Mountain's roughly 6500'.Then i go back home and the Overhead read-out will only read 800 km,after about 3-4 Tank's of Fuel it will return back to normal.It seem's to be harder on Fuel for that time period.

Has anyone experienced this Problem and is there a FIX
