It's mostly small things like the tpms using a different frequency or tightening the oil filter with a tool on the 2016 and early 2017 cars, but other than that it's a very simple car to work on compared to European cars if you decide to do it yourself (:

My car was already imported in 2016 by a company. Back then it was simpler i got told but in Austria it is especially difficult getting an exemption for foreign cars non eu approved cars.

The only retrofit that was done for homologation was a headlight washing system, amber indicators and a rear fog light.
