I think I have an old version of OBD-II in my X. (2000/05 build). It may actually miss terminal 15, whatever that is. I eyeballed the connector pins and confirmed that there are several unconnceted pins compared to my 330ci. FYI, here's the OBD-II connector diagram.


I will double check what's connected in both of my vehicles. Jose, please check with yours and report which pins you have.

On the other hand, I don't have the same error with my 330ci but have a new error.



Can anybody help?
