Fiat Doblo 1.3 Multijet Odometer Flashing

[ptmiller55]

Hi all, hope someone can guide me in the right direction. I have a 2015 1.3 Doblo which the odometer has suddenly strated flashing and it wont stop! Any ideas as to how I can find the fault and how to fix it please. It first started when I had a bad earth connection on my battery, I replaced the earth terminal cable which sorted the bad earth but the mileage is still flashing!

Cheers
Paul
