Thanks Jose for your inputs.
I think that later models may not have an OBD port under the hood or the pin layout might be different than the older one like mine. Anyway, it worked for me. Great!
However, the problem with my 330ci persists. I am pretty sure it does not have a second OBD port inside the engine room (need to do some research), so it may not be easy to troubleshoot it without expert's inputs from you guys.

Great, glad you got it working.
I was going to suggest the exact thing. As I understand it, the round connector is a BMW proprietary connector. So, for later models BMW went with the standard OBD connector.
Obviously, all my DIY are for facelift models but maybe you can help out now. Can you take pics of the location in the engine compartment and of the actual connection then post or send it to me. Then we can add it to the first post. I'm going to add the pics I have of how to connect the cables so that would help.
On the 330ci .. what year is it?
