Some sort of BMW specific codes....I guess that scanner couldn't read them. Only thing I noticed that was out of the ordinary at this time was the car was idling high, a little over 1K (I'm normally at 750). I turned the car off, waited about 5 seconds and fired it back up. All was well....no malfunctions and normal idle. I'll be taking it in this weekend. What do you guys think? Idle control valve?

Definitely throttle actuator, take it to the dealer right away.
