The X3 records in miles and its not switch-able like the E90 (which has 33.600km). I purposely wanted to report what's on the odometer instead of doing a conversion and possilbly missing a few decimal points, thereby making my kilometerstand less than precise.

I plan to switch over the consumption over to l/100km. However, changing distance over to km will permanently throw off any service records and state inspections and cause more trouble than intended, even if I don't plan to sell the vehicle anytime soon.
