:bang:how do i stop flashing odemetre

Your car needs 'proxi alignment' which is a fancy way of saying it has a software glitch needs to go to fiat or garage with suitable equipment.

Either that or something isnt plugged in/ Working. I forgot to plug my heater controller in at the weekend and now the milage flashes.

Is it a new car or an old car out of warrenty?

Eitherway - ask the local fiat stealer
But also ask the local auto-electricians as well - they can do it

I got my local Sparky todo it for £60 instead of fiat wanting over £200!
