E30 Zone

anyone know if the m30 afm 027 and 018 are interchangeable?

Basically im after another afm and currently have a 027 afm on my m30, there is a 018 one localish to me but not sure weather it'll work on mine.

I'm 85% sure no, different electric scales as the flap moves. Ps) I run an M30 AFm on my M20
