Technical Digital dash blinking

[wifimaster]

Hello everyone, I have a 1990 fiat tempra 1.6sx cng, 300000km
I have a problem with the digital dashboard, when it's cold outside starts to flash for 10-20 km and is unable to save the mileage.
Does anyone have any experiences?

Thank you

I'm thinking it is a connection issue at the back of the dashboard.

Disconnect the battery. Remove the dashboard and un-plug and then re-plug all the connectors. As you remove and re-plug them apply a little side to side wobble to help clean the contacts.

Ideally you need to use some "switch cleaner" or alcohol as well.
