Where is the diagnostic plug on an m40 engine (318i cab)?

Do you have the right hardware and software to read any codes/information?
The port is indeed the round cap with 21pins underneath it.
Something I ended up realising with the E30 is that it is largely pointless using diag software.

In that case, a paperclip is all you need on it, really very useful piece of technology.
