Have tried multiple resets, and even tried a static reset using INPA. But no luck.
Just ordered the Autel TPMS TS401 scanner from Amazon. Hopefully that will help in the diagnoses.

My first thought is they used the wrong sensor maybe. BMW changed the TPMS protocol in late 2010, same frequency, but they're not interchangeable.
You should be able to reinitialize the system yourself through Idrive or the BC if the parts are correct and working, no special tools needed.
