All of the modules don't turn on when you wake the car up by opening a door. I believe it is only a few that are associated with a particular bus. The e70 is a new gen BMW with a more complicated communication bus...but the old gen BMWs (like the e38/e39/e46/e53/.etc)...only a few modules on the K-bus & P-bus come online when the door handle is lifted. These are modules that start up in preparation for an all system go scenario (IHKA temp fan sensor, door microswitches etc). If the vehicle was optioned out with all those options like auto climate, anti-theft alarm systems, electric windows, electronic central locking...then it wouldn't be necessary to have these modules come online in expectation:
{this is the old gen BMW Wake-up & Sleep criteria...again the e70 has even more features and more online technology and different bus system and modules...but the criteria is similar}
