Hi,
Found these kicking around, anybody want them (message me), can use B800 to reset airbag warning light and INPA software and USB connector with laptop to get into the BMW diags, however be warned its a bit complicated to setup (follow instructions on the web) it took me a few attempts but you can check all sensors, etc.
