Funny. I felt that way after I bought my first and last BMW. Got a 2000 M Coupe, brand new. $40K back in 2000. Beautiful car. But, had the following issues: after filling up the fuel tank, the fuel needle would bounce from empty to full for the first 50 miles (known issue for 3+ model years). The only fix was to cut into the rear firewall behind the seat and replace the sender, which may not have fixed it. You're going to cut a permanent hole in my new 40K car? NOT! Rolled passenger window down one day and when I rolled it back up, black goo was smeared across the window. Rough idle and hesitation at start up until the engine warmed up. Known issue for 3+ model years. A computer FI adjustment mostly solved it. One day I closed the rear hatch, which broke the internal latch. Known issue for 3+ model years. The final straw was when the passenger door wouldn't open from the inside or outside.
I hit the forums and, like you, uncovered a case of cans of worms. The part that was disgusting was that BMW knew of all these issues and didn't bother to fix them for 3 years. Of course the BMW groupies on the BMW forums justified all of it with "it's a specialty car". No thanks.
Anyway, as mentioned before, forums are mostly inundated with problems people have of whom are looking for resolutions. So don't sweat it. But, you are now aware of a potential issue which gives you power if you need to talk to a tech at a dealer.
How many miles you got so far and let us know if you develop the issue (which I really hope you do not).
