The FL2 S8 is Euro 4 compliant, three years ahead of time. I think FL1 is Euro 3 though so they might not be exempt.
Rather comically, the only changes I can discover between Euro 3 and Euro 4, from a D2 perspective, is individual control of the variable cam timing (FL1 controls them both simultaneously), and a warning light when the secondary air system is faulty (FL1 logs a fault but no light). The engines are mechanically and electrically identical - its purely software.
