fuel mixture fault codes help.

My09 335i have been throwing these codes lately. The can runs fine even during WOT but the SES just keeps comming back even after clearing it with BT cable. The car is stock. I've tried searching but there is no definite answer on how to get rid of these codes so if someone can chime in and point me in the right direction it would be greatly appreciated.

here are the codes that keep popping up.
