I am working on a 2011 e90 335D that has been giving me a hard time with diagnosis. Car has 80k miles

I am getting codes:
40D4 Exhaust gas recirculation controller, position control
46F2 deNOx System Function
4D16 SCR System Efficiency

I have completed the Ista SCR system test numerous times. First time it said replace Nox sensors, so I did, reset adaptations and went for a drive to set everything, came back with 4D16 codes still. Did EGR test, test came back a bit slow, cleaned the EGR, code went away on the 2nd drive, still got 4d16 code. System test also said to request regen as it detected a loaded DPF. Drove for 2 regen cycles and recompleted the SCR system test, still get a loaded DPF message and to drive again. This has happened twice now. Is this pointing to a bad DPF? or something else?
Here are the screenshots from most recent SCR test.

What motor temperature does the car run at?

per the screenshot, it read 87.86C. On every SCR test ive done, its been around that same.

Any suggestions?

If your motor runs at 88 then the next thing is to clean the urea metering valve. It’s easy with warm distilled water. Also, looks like you have EGR code 40D4. I would address that as well. Could be just dirty.
