flashing odometer is an indication that there is someting wrong with a device on the CAN bus. Could be anything (aircon, lights, locks, windows, etc.etc. Could indeed be related to Blue&Me.
Best is to read the error(s), and/or do proxy alignment.

 

I understood right up until reading the errors and proxy alignment. How does one go about these?

 

You can either do it yourself, if you have the soft- and hardware, see f.i. Multiecuscan - Diagnostics software for Italian cars
or via the dealer.

It's a relatively simple process whereby you plug a tester into the OBD port/connector, read the error and execute a command to scan all the devices on the CAN bus
(CAN bus is the in-car network through which a lot of the devices in the car communicate)

This is of course assuming nothing is actually defective (such as blue&me), otherwise that will of course need to be fixed......

Sometimes it's just a matter of a glitch/lost sync, that can be solved by simple proxy alignment (= Reacquainting and resyncronising all devices on the bus with the controlling computer (bodycomputer) )

 

How old is your car battery? I had the odometer blinking because of low voltage from the battery.

 

I am unsure. I can't find any receipts for a new one. I've seen a few people suggest disconnecting and reconnecting battery?

I have an Alfa specialist near me. I assume they would also be able to do this?

 

I get quite a few Guiliettas coming in with flashing mileage and usually it is either related to faulty B&M controller or wiring issues in the boot loom.

 

flashing odo means there is change in set of units seen by can bus vs one programmed during proxi alignment. may be b&m unit not resonding to be the reason, since you reported this stopped working.

disconnecting and connecting battery may help in case b&m hanged up for good (pre first facelift giulietta ones ares till windows ce based, as far as i know)

I would check also fuses, there are 2 for b&m unit one direct 12v f36 and other through ignition f51.

thats for start. if you wont solve it that way, then maybe cabling get damaged, connector makes no contact or unit died (rather unlikely)
