29FB00 - SCR SYSTEM WARNING 1
0F1650 - 480134 - ICM NOT ABLE TO TELL DIRECTION
0F1D50 - 8051B5 - RETURN PUMP
0F17C0 - 8011B9 - POTENTIOMETER
8011F9 - HEATER REDUCTION IN POWER
These are all my codes, but the car drives perfectly, no rough idle, it has all of the torque and overall it just feels good, but it seems like a lot of codes

I'm not sure how you got those interpretations of the codes. I pasted the actual code descriptions below.
From the Engine Control Module (also known as the DDE):
0x273600 Exhaust gas recirculation position, long-term drift: Position deviation too high (current / new condition) (*clean your EGR valve. If it returns, replace it)
0x29FB00 DeNOx system, warning and shutdown scenario: Warning level 1 (*likely a stored code from when DEF fill was too low, or of low quality)
The ICM code is likely old and insignificant to anything. This comes from the Integrated Chassis Management module; nothing to do with engine.
0x480134 SBS function - direction of travel unsafe with velocity greater than 2 m/s
SCR (selective catalyst reductant) module code. Have you put in lower quality DEF in the past? This + the DeNOx system code earlier point to a bad DEF fill once. It may be an old insignificant code.
0x8051B5 SCR return pump, taught volume outside of valid range (DFC_SCRPODVolLrnBFP)
Climate control codes from the IHKA module, both insignificant old codes and can be cleared:
0x8011B9 Layering potentiometer: Short to plus or open circuit
0x8011F9 PTC-Module: Reduction of heater output due to power management
