Interesting, I didn't know that. Your first link pertains to diesel, as far as I can tell the EPA instituted the 10 ppm limit for gasoline in 2017
The limit was 50 ppm and 10 ppm in the EU in 2005 and 2009, respectively according to your [1].
I've got an N53 engine[1] which was introduced in 2006. This[1] page shows it and a few other BMW engines weren't sold in North America for fuel quality reasons.
As far as comparing long-term reliability numbers it amounts to the same thing. US numbers can't be trusted for EU consumers. We've got 10 years of data at 10 ppm, the US just 2 years.
But the main reason I'd distrust it is consumer bias. As shown in [2][3] BMW is as common in Germany as Nissan and Honda in the US. I live in The Netherlands where it's about as common to see a BMW (5% market share, 2% in the US).
