Front O2 sensors???

What is your question?

My 2003 BMW 325i computer says "Service Engine Soon". Code reader says "left bank lean" and secondary code says "right bank lean" so would this mean I just need to replace my 2 front O2 sensors? Thank you for any input you can give me

Maybe; I would use the code reader to check all the sensors to see if they are ready, if it has this function.

Code reader is only giving me two diagnostic codes. I know I have 2 front and 2 rear sensors...but it is only showing fault in two.
