First of all, your post does not belong in this thread. This thread is about logging. So move it to the N54 (edit: N55) engine thread.
Second, scale your pictures for gods sake
Third, if you want someone to help you, help them first by providing information about your vehicle and the history of the appearance of errors you are concerned about. What are your mods, your map, your fuel?
That said, you do realize you are getting a mixture control code? 29E0? That's why your OBDII flags for oxygen sensor won't set. Could be any number of problems but one likely possibility is a dead or dying pre-cat oxygen sensor in bank 1.
Download BMW standard tools to your laptop, and use INPA to read the voltage output from the oxygen sensors.
EDIT - just noticed you have an F30. Why are you posting in an E90 forum?
