Break-in is simple and in the Owner's Manual, which you can dowload from BMW web site. Here's the section from my Owner's Manual:

Breaking-in period

General information
Moving parts need to be broken in to adjust to
each other.
The following instructions will help achieve a
long vehicle life and good economy.


Engine and differential
Always obey the official speed limit.

Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:
* For gasoline engine, 4,500 rpm and
100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode for the initial
miles.


From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.

Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full traction
potential until after an initial breaking-in period.
Drive conservatively for the first
200 miles/300 km.


Brake system
Brakes require an initial break-in period of approx.
300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and discs. Drive moderately during this break-in
period.


Following part replacement
The same breaking in procedures should be observed
if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
