AFAIK there are quite a few things that BMW USA replace which aren't done over here..We're quite a knowledgable forum on BMW's thanks to some great members - they also have same issues. VANOS seals anyone? Swirl flaps? Fox was just mentioning the other day his e39 had some sort of issue that BMW USA is replacing yet BMW UK won't for some reason.
And don't forget the sub frame issues on the Z3 and E46 Coupe..
