Mein Auto: 335d
My GF has an 01 X5 3.0 and in the summertime her mpg's were routinely in the 13's. Your X5d will get better than what you are showing right now. Give it time. Winter time will be your lowest(cold weather/winterized fuel) and summertime will be much better. My 335d has seen a low of 22 and a high of 36+. Just remember the X5 is much heavier and has more drag than a 335d. I did talk to an X5d driver one time and he said he was averaging 19 mpg.
