Manhart does not make it either. They just sell them. I forget the German company name that makes them. I saw a thread on the 1er forum awhile back on this gauge. Its way over priced though.
Yea... there is also that iPhone app. You plug in a small WiFi (or maybe its BlueTooth?)plug into your OBD-II port and your iPhone connects with it and you can display all the OBD-II data and even read codes on the fly. Pretty cool. But it was also a few hundred I think. The one I remember is this KiWi one...
These might be of interest too...
