Break in oil change

[330i2X5]

Having read many many posts over the past few years about changing the oil after break in to ensure better peformance, I decided to email my dealership to request the same....Im at 1500km now and almost at break in....
So when I received the following email I was a little surprised and now not sure of my next step:

The "M" vehicles are the ones that we usually do a break in service for due to the type of oil and because it is a high performance engine. I just spoke to ***** about your X5 and he has told me that the engines are pre broken in and because we use a full synthetic the chances of debris are slim to none. But after saying that if you would like to have one performed for piece of mind I would suggest waiting until you have gone over the 2000km mark as that is when we perform the 2k service on the "M" cars.

Engines are pre broken in????
Is there something we dont know ??? I know this master technician at BMW is highly knowledgeable...
