I just got mine to work!

Turn the key to on/run but do not start... Wait until the beeps end... within a second or two of the beeps ending there will be an oil icon and a clock icon in the displays... while these are showing press the button twice within one second... your oil level will be displayed... my car was not exactly level, but close... i got an "OK" display, which confirms yesterdays "hood up" check... i guess it really works...

The service reset was a little more tricky but i got it done...

Follow the directions in the manual exactly a lot is based on timing of your procedures...

Very cool...
