I'm having the same problem with my 320i. I've contacted my local BMW dealership to get their statement in this matter.
Strangely I get no results when searching for this issue in danish. I cannot be the only dane with this problem. E90's have sold plenty in DK...
320i E90, Black II, 17"/158
Skoda Octavia Scout TDI
