Thanks trader4, Ricky Bobby:

The scanner is a PWOW ELM327 wifi unit with the OBD Fusion app on an iPad.

Spark plugs were changed 20K miles ago. I had run SeaFoam through about 5k miles ago, and my indie shop ran BG K44 through about 3k miles ago. The X5 seemed to run slightly better when the additive was in the tank...

Instructions to reset the throttle body adaptations?

UPDATE: Found this --> With the car off, turn the ignition to the on position(posit. 2) for 10 seconds(do not start) then turn the ignition off for 10 seconds. Then start the car.

Also - can the ELM327 wifi be hooked up to a laptop via wifi and use INPA compatible s/w?
