I see that new sensors have to be 'adapted' to the ecu but I read it's a one shot deal, anyone know why?

 

Would it be possible to remove a sensor, adapt another one, and then re-adapt the original one?  

 

It's not something you commonly come across. Which sensor are you looking to change in which car?

I've changed the DPF differential pressure sensor, all coded, no issues, I'm just curious why its a one shot deal and whether that could be got around using another sensor as I described.
