The car I was working on would throw consistent O2 sensor codes after enough driving....

I read about problems with the barometric sensor in the DME causing problems (on E46, E90, E92s), but no solutions or fixes other than a repaired DME.
And Happy, I've looked carefully at the wiring all the way back to the DME, and nothing looks worn or torn. The DME still looks untouched.
So, I don't want to be the guy who opens up a perfectly sealed and working DME, if nothing is amiss inside, so I'll try my Android app "BimmerTool" to see if it will give me data on the baro pressure ( it has a PID on the live data list for it). My other Android apps, Torque Pro and OBDLink, have a similar PID, but don't show data.
I haven't seen anything on my Foxwell about baro pressure, and I'm so far out of practice using Inpa, that I will have to learn all over how to use it, that I might not be able to verify if there's a baro pressure problem causing the MAF to read incorrectly. Also, the O2 readings look good, no matter what MAF sensor I'm using (wouldn't they show a baro problem as well?).
