fail CA smog

I have recently purchased a 2008 m3 and I need to get it smog check. It passes all emissions tests but testing OBD self tests it spits out "not complete" for Catalyst and Oxygen Sensor.

I took the car into BMW and they say they are getting no errors. I hooked up a OSB sensor tester myself, I get link errors and can get no readings what so ever. Bad fuse?? but would BMW find that?

I am not sure what to check next and any recommendation would be grateful.
