So it is completely consistent that we hear about more North American pumps failing.
IF this somehow turns out to be fuel related, whether it's just another smokescreen or an actual contributor, does not somehow get BMW off the hook for anything. They know exactly where they sell cars and have been doing so for decades - it is up to the manufacturer to produce a product that lives up the customer's satisfaction within the market they bought the product in. It's not like we're all importing these grey market from Europe - these are cars certified North America, and should work as well here as anywhere else.
The only thing related to fuel one might reasonable hold is that we have gasoline DI, not diesel DI. Diesel DI has been used for years and quite reliably. Many, but not all, manufacturers of gasoline DI engines have experienced problems with the fuel system, but none to the extent with these fuel pumps.
+ largest market for bmw is USA
+ largest market for large engined, high powered engines is USA (ie. 335, 8 cylinders etc)
