Some discussions on other forums mentioned that 320i in other countries can come with a low compression option S858A and 10:1 and same 7079 part# as above, or without option S8585A and 11:1(and a different engine part #). One possibility is that the bmwusa data sheets are correct, and US spec 320i N20 is with S8585A option.
