After weeks of searchs and for studying, finally i've found the right chinese solution for DSS.

They are like OEM (i think they are OEM because chinese production for all car brands) and are almost plug and pluy (i never have find a retrofit that doesn't need some little adaptations.... I made a lot of them on my previous BMW F11).

There is only a big trouble in my car. I don't find the rear trunk OEM obd plug.
It should has been there (right side near the battery) but nothing. My car hasn't it.


To better explain i upload in my gallery two pictures (one with orange circle where the OBD plug should be -it comes by seller fitting instructions - and one coming by my car with red circle and that damn obd plug disappeared).

Has someone of you any clue?
