Using AlfaOBD on a 2022 Fiat Ducato Series 8 no matter what values I enter for the tyre pressures I still get told that they are outside of the allowable range. Is there any way of determining what the allowable range is or bypassing this message?

I'm afraid you have a SGW that blocks 2 way communication. You will need to go the official route.
I've found and bypassed the SGW and have been able adjust other settings including a proxy alignment. It's just this one which won't play ball.

Well thats almost good news.
Yes, but considering that changing the TPMS pressures was the main thing that I wanted to do then perhaps not so good news.
