Is this the Vanos Solenoids or my accidental E85 mix? 2d60, 2c58, 387F

I was running my car at the drag strip on Saturday. Short story, my daughter borrowed my car and I ended up with an unknown mix of E85. She knew I ran it but didn't realize it had to be an exact mix. I ran the car hard on this mix not knowing it was like that. Had lots of misfires and eventually the codes and reduced power warning. So I started trying to see what was up. As far as I can tell she ran my car to a 1/4 tank or so of gas and then added almost 5 gallons of E85 not understanding the car needed a mix. After I figured out what she did I filled it the rest of the way up with 93 and re flashed the car for a 93 tune. It ran fine on the way home and the next day but then I got the codes listed above and the reduced power warning again.
It may not even be related because the codes seem to lean towards a Vanos issue. Does anyone happen to have any suggestions or insight? Mods are in signature.

Rule 1: Don't let daughter drive modified BMW.
