Oil pressure regulation valve and Heater support pump DTCs

Hello, recently, my MIL indicator lit up and once I got my simple OBD reader out, I was presented with this:

To my surprise, I have not found anybody dealing with this, especially the combination. Since both came on together, I doubt that either the valve or pump failed at the same time. So maybe I'm dealing with some cable damage? Or does anybody have an idea what this could be? What troubleshooting steps would you recommend? I've drove multiple times with it without noticing anything unusual.

T6.1, MY2019, 2.0 110kW, 4MOT, DSG, CXFA.

Thank you for any ideas!

They could just be erroneous errors of no significance, especially as you have no drivability changes.
I would delete the Diagnostic Codes.and see if they come back in the first instance.
