Ok. Found this:

 

Did you ever get any of the codes you had sorted out? Wondering if you could have some bad grounds/connections knocked loose. These trucks are horrifically dependant on the electrical system working flawlessly. Ask me how I know.

 

Check Engine was P0441 and P0174. A Mass Airflow Sensor and harness replacement erase the check engine.
For TPMS, I think all the sensors were removed. Thinking about re install or just ignore it for now.
About 8 codes are because the use of cheap leds bulbs inside and the LR4 rear lights. Looking for a better kit.

 

I'd forgotten about the lightnulb thing. I had a first generation north american spec sprinter that was the same way.

 

New clockspring arrived today. Hope to clear that airbag light.
There is a 2016 LR4 HSE Lux for sale ($20k). Thinking about exchange mine. Will see…

 

2017 D5 Td6 HSE with 91k is the new one. And the end of this journey. Very nice maintenance history at JLR Puerto Rico.
