When I went to Munich for my ED, I toured the factory where they build the N20 and a few M engines. We were the only English speakers there that day so we had a personal tour guide through the factory. We asked a lot of questions, and one of the things revealed to me during that time was that BMW does hot runs (up to 160mph i think?) on all of its M engines, but with the large volume of N20 engines it produces, it does not follow the same procedures that it does on the M performance engines. I believe it was specifically mentioned that they do not bring the non-M engines up to high speed as they do with the M engines.
