There’s a whole forum -
https://f30.bimmerpost.com/forums/fo...play.php?f=383. I believe there’s a forum like this for every model of every generation, but I can’t swear to that.
I agree it would be nice to be able to look back into the past more easily. If you google for a particular model and year one of the suggestions that almost always comes up will be a link to the correct page on Bimmerpost.
