Need help clearing code

I have an e46 with a service engine soon light, I have gotten it diagnosed and it appeared to be an 02 sensor code. I have swapped a few parts and was wondering if someone could try and clear the code for me now. I am just a bit north of SD not looking to travel too far.

I'm betting it was a P0171/P0174 as that's what most people relate to being an oxygen sensor. It isn't, it's a vacuum leak. You do a smoke test and fix wherever smoke comes from
The code should clear by itself if you fixed the issue after a few drives
Not so complicated install of BMW Tools (Windows XP, 7, and 10)
