crystalworks is on a distinguished road
I don't believe the ehc2 is tied into the tpms (forget BMW's acronym for it). If you had a flat it is likely a puncture or a valve stem or valve stem core that is leaking. I had to replace a core (the actual valve in a valve stem) because it had a slow leak on one of my other cars.

Good luck with the coding. It's not overly complicated but not overly simple either. Hopefully the threads on the subject is enough to guide you.
