Here in Europe we don't have that on our diesel's.
I think it's strange that there are that difference from Europe to US.
What does it do? I know it's something with emissions but exactly ehat does it do?

When EURO 6 comes into effect, higher power diesels will use SCR (selective catalytic reduction). It chemically reacts with the NOx in the exhaust to reduce it to H2O and N2.
BMW used the North American 335d and X5 35d as test platforms for the SCR systems they will be fitting to Euro-spec diesels.
Ironically, American emission standards are currently more stringent than EURO standards. Who'd have thought?
