That is annoying the BMW does not replace them.
I understand the "we dont cover interior clause" cause some people should just be shot when it comes to the interiors of cars (my wife is one of them)... but they acknowledge that it is a wear and tear item, due to what must be a bad design material usage, so they should fix it.
Audi's are the worst for this, a 6 year old Audi interior is a sad place to be in....
