Default Smog Not Read - Fuel System Monitor

About 2 months ago I had a misfire in 2 cylinders and had coils and plugs replaced, CEL reset, etc.. on my 2012 550. Had to get a smog check last month and tech informed I had several monitors in a not ready state. I attempted the BMW drive cycle but haven't been able to complete it in it's entirety. I took it back to the smog guy and now just the Fuel System Monitor is the only monitor not ready, so I'm close. He indicated the Fuel System monitor is one of the easier ones to get "ready" so he's kinda baffled but I don't have much confidence in his knowledge of BMW's. If anyone has had any experience with any portion of this and/or specifically the Fuel System monitor I'd appreciate some feedback as this is driving me crazy.
