airmass flow meter

im trying to replace my airmass meter. reg w174xcw, the one fitted is bosch 0281002180. but these seem for vauxhalls so im assuming its wrong one. which do i need? i need sell car as its just gone thru mot and i want it to run right. i did try 0281002182 but while it fitted car, it didn't fit air filter box. unless airfilterbox is also wrong. any help? anyone near st helens merseyside with same model, 2.0 di that can compare?
just to be sure, even the di has a turbo? as my engine does.

I need the switch that connects to airmass meter. Anyone got one for sale? Previous owner butchered wiring to use a vauxhall unit. Text number above and i will ring you. Thanks. For a freelander. W reg. 2.0 td. Di.
Thanks
