So what is the problem then? It is just 'a glitch'
well the flashing mileage is simply the cars way of telling tech or anyone who cares that the can net work is not aligned
after alighnment it should stop doing this
now sometimes it's doesn't that means something is knocking it out
as t4 says power and earthing isues starter motors or alternators are the most common cause on older vehicles but no entirely impossible on newer ones
or anything connected to the network most commonly the convergence systems as fitted to puntos 500 pandas hence why the problem althou it can happen on any fiat vehicla with a can network dating back to 2000 it seems to be isolated to newer fiats as listed above
then the less likelly things bad connections or wiring on the can lines it takes 20 seconds to test can wires coincidently not a majour warranty time claiming issue ay
pin 6 and 14 on the diag plug iirc t4
then there are the 2 items that contain the the acurate timing clocks for the can network body computer and dash pod
i believe there are some other procedures to carry out aswell as proxy alighnment on cars that have rear parking sensors and convergence to make sure they are properly configured with the body computer and dash pod not sure i'll try find out unless t4 knows
a wile ago i wrote this don't know how you all missed it
https://www.fiatforum.com/500-technical/149254-flashing-mileage.html
and again it's absolutely not axceptable for a dealer to justify not doing anything
all they need do is check on fiats system for updates and install as appropriate there may be some buy now much like you computer at home is constantly updating it's self from windows again updates for convergence
proxy alighn the car after installing anything
configure what needs to be as said i'm not sure on that i'll check thou
then check can lines and send car out again
i can gaurantee in most cases this lot wil have been overlooked and at the most a proxy alighnment done witch tbh in most cases does the trick
if it still plays up then the garage need to open a case with fiat technical and they will then advise on what they are allowed to change in order to fix the car and more importantly for the garage point of view what they are going to be allowed to claim time and money for
if this is not being followed and there telling you there's nothing wrong with your car then simply contact fiat customer services who will then give the dealer a good telling off ok
hope you get your car fixed soon and good luck to all who are affected buy this new problem fiat are working to solve
i'm thinking it might be a good idea to put up a sticky threat to ascertain exactly what customers are doing at the time it starts to flash be it turning on the main beam or connecting an ipod anything
for a usefull database in order for tech using the forum to get to the bottom of the problem quikly and try to work out what is actually causing it tbh it's the biggest customer feedback we have so might work out well as allot of people on the forum have had this happen

sorry to hijack your threat and for everyone else it's a little blown out on one of your problems but i agree also your other niggles should be fixed and that is unacceptable and another matter to bring up with fiat customer services
