It may be "said" that BMW breaks-in the engine at the factory, but it wouldn't be true.

In 2005, I visited the plant in Munich where the N52s and the V-10 for the E60 M5 was built. The high-volume N52 was tested on a machine then installed in cars. The V-10 was hand-built and tested by hand.
When I picked up my F30 last July, I toured the factory again. The N20s and N55s were also being tested for a few minutes in an automated machine then assembled into cars.
Oil change discussions on BMW forums are like religions: everone's is different.
For my part, I can't see how it's good for an engine to go a year or 15K on the original lubricant. I had mine changed at 4K miles.
