  Live Values on GAP IID - Bank 1 vs Bank 2 and N/A values

  I've bought a 2nd hand LR5 after owning an LR4. The car has been used and isn't in perfect mechanical condition but the oil change was done timely. I'm now trying to fix up the minor/major issues.
  
  A DPF Full error came on suddenly. I've watched some great videos, read through forums and now trying to put the dots together for myself using the GAP IID tool.
  
  My engine is a 2017 3l TDV6 190 kW and codes on GAP tool are the common overboost (P0234-77) and P2463-00 Diesel particulate filter pressure sensor B circuit range.
  
  The value is not stuck in a closed position and moves freely.
  
  Looking at the live values through the IID, the soot mass is ~3g and the Particulate filter differential pressure approx 7kPa at 3000 rpm so I don't think the "Red Full DPF , see dealer light" is actually a full DPF. Especially since it came on suddenly with no amber warning prior to suggest a regen.
  
  Following some videos & posts, the oil separator seems to be a reoccurring theme so I have ordered one of those with the seals since it wasn't too expensive (relatively speaking).
  
  I found the MAP sensor and it was predictably filthy and blocked. I've cleaned that and would now like to 'check it'.
  
  Unfortunately, I'm new to the GAP IID tool and I am not sure what all the N/A readings mean. To name a few:
  
  
  Mass air flow N/A
  Mass air flow sensor B
  Mass air flow sensor B - Supported
  
  Intake manifold absolute pressure A
  Intake manifold absolute pressure A - Supported
  
  Intake manifold absolute pressure B
  Intake manifold absolute pressure B - Supported
  
  Diesel particulate filter - Bank 2 - Inlet pressure
  Diesel particulate filter - Bank 2 - Inlet pressure - Supported
  
  Diesel particulate filter - Bank 2 - Outlet pressure
  Diesel particulate filter - Bank 2 - Outlet pressure - Supported
  
  Intake air temperature sensor - Bank 1 - Sensor 1
  Intake air temperature sensor - Bank 1 - Sensor 1 - Supported
  
  Intake air temperature sensor - Bank 1 - Sensor 2
  Intake air temperature sensor - Bank 1 - Sensor 2 - Supported
  
  Intake air temperature sensor - Bank 1 - Sensor 3
  Intake air temperature sensor - Bank 1 - Sensor 3 - Supported
  
  Intake manifold absolute pressure A
  Intake manifold absolute pressure A - Supported
  
  Intake manifold absolute pressure B
  Intake manifold absolute pressure B - Supported
  
  
  Any help interpreting Bank 1 vs Bank 2 and what a N/A value means (does it mean there is no signal or is it just a placeholder for a sensor present on other models etc..). Are N/A values for these sensors on the TDV6 normal.
