It seems from a bit of interweb surfing that the iDrive started tracking servicing from the 2014 year model year, so those above are correct.
However, an interesting development, the dealer said he double checked with BMW and they have no record of any early services in their system. So it would seem the car was a bit over 2 years old and had 28,000 on the clock before it saw its first service.
Since then it has had 4/5 non BMW services at regular intervals covering the additional 17,000 miles it has traveled since.
Question is, does that lack of early servicing constitute a major issue, or with today’s longer servicing intervals is not a big thing? For info the car is a 28i, so there are turbos and the like in the equation if that makes a difference.
