Not sure if I undertand the question correctly.

But if I did, I think it has nothing to do with the X5 but rather with the types of pumps at different gas stations. Some pumps tend to stop when there's still a gallon left and some pumps stop when it's completely full.

It has not mattered lately since the pumps here in L.A automatically stops at $100.00 and you have to re-swipe your credit card if you want to continue filling up.
