P2271- O2 Sensor Signal Stuck Rich Bank 1 Sensor 2
Does the diesel even HAVE O2 sensors?????
P2a01 refers to an error on the same sensor.....
P013a is slow response, from the same sensor.....
P2bac is nox Exceedence - Deactivation of EGR
NOX is high. Why becomes the question. Think I would replace the sensor in question, clear the codes, and see if everyone is now happy.

Likely going to be a wiring problem then. I suspect the other two codes will come back eventually as well....... Of course, it may also be a fueling problem, but, I would expect to see different codes for that...... Diesel really isn't my strong suit though.... so, hopefully someone with more of a clue will be along.
