I'm guessing that only an expensive Fiat diagnostic machine can do this? The days of pushing/holding a button on the dash whilst turning the ignition key have long gone hey??
I think it's an option in the menu that's accessed with the headlight adjustment buttons just below the radio?
MultiECUScan should do it
you've not stated which engine though, some will require more resetting than others
DPF , oil degradation,
Multiair unit,
etc.

Really?? Please tell me more.
If you have the handbook, all the options available from the menu are explained in there - there's an horrendous thunderstorm going on outside at the moment so I'm not going out to get mine (so there).
