As per the title, if I can find a FIAT Professional agent locally at reasonable cost (but not North East Yruck and Van York where I've had, horrendous personal experience,) I'd use them to be sure not to have warranty issues in the remaining 2.25 years FIAT Camper Assist cover.
Otherwise, I'll be down the less secure route of FIAT parts fitted by independent garage with a detailed invoice, naming parts brand as FIAT.
