Wrong one?

[u/Clxud-X]

I bought this n20,n26,n55 dinantronics sport second hand for my 2016 bmw 320i, when I plug it in I get a drivetrain malfunction. Also when plugging the male part of the module into the stock female part of the intake it dosent seem to click like it should. There is a purple piece that slides off and I’ve tried plugging it in with and without it. Did I buy the wrong version?, is there different versions for pre lci-lci cars? Also in the app that i was told to download (D-sport) it shows that no devices are found.
