I have not seen any level between MIN and MAX on my 8/2011 X5 35d. My oil level did go directly from MAX to MIN three times before I checked the oil (the diesel has a dipstick) and added a liter. I had completed 13 hours straight of driving and several short trips with nary a problem. Over the next couple of days and a dozen trips or so I started getting the level warnings, three of them.

I, like others, lament about the lack of a dipstick on modern BMW engines and maybe that's living in the past, being sappy or just nostalgic but they could have at least provided an electronic level indicator with some resolution or granularity. Instead we got a cheaply implemented level switch. Couple that with the absence of an oil pressure gauge and a complete lack of ANY temperature meter and you have the makings of a disaster.
