Hi i am a newbie , i live in huddersfield and just had a new radio fitted in my fiat 500l and now the milometer is flashing. I have told i need to go to a fiat garage is they anybody out there who could help . Thank you in advance
Yep, that is all true, the mileage flashes as you have done a configuration change (fitting the radio), so a proxi alignment is required (CAN SETUP).
This can be done either by a Fiat service garage or you can do yourself if you have the Multiecuscan software and a modified ELM327 with a Yellow ELM327 adapter.
I have used an ELM327 1.4 and adapter from Aliexpress and used a knife to cut out a resistor (if you are desperate you can buy one already modified off eBay but I have had bad experiences with those) and the rest of the magic is done by the software
