While working with the Peugeot dealer I got a Bipper and could not reset oil service the usual way. They had an extra tool (box) to connect between the Diagbox software from Peugeot and the car (extra interface) after which it could be done. Something to do with it being Fiat , so maybe you can do something with Blipper while using Fiat software, not sure about this however.
Maybe Support could update on this?
