I believe you have to complete the above sequence with the ignition switch all the way on, but engine not running.
Congrats on the purchase. I bought my latest M with over 100k miles and only one owner. The guy did every single service at the dealer, so there was a list of maintenance over 5 pages long! Was awesome to see, but in the back of my mind I felt bad for the guy... the stealership quoted him $2500 to fix a valve cover gasket leak (probably why he ditched the car). I fixed said leak in 5 minutes for free by torquing the nuts!
