Faulty Blue & Me Control Unit on a Fiat 500 with Mileage Flashing on the Dashboard

Model: Fiat 500 312 - Years 2007-2024
Part: Control unit

In this video, we see the cause of the flashing mileage on the dashboard of a Fiat 500. Diagnosing with an OBD SCAN revealed error codes P0022 and U1733; along with the flashing mileage, an abnormal battery drain and non-functioning Bluetooth were also noted. The problem is the Convergence Blue&Me control unit located on the passenger side next to the glove compartment: there, you will find a cover, unscrew the 10 mm nut, and remove the carpet from underneath to pull out the control unit. If you want to buy a new one, you can find it on centralinemotore.com with the code 51884624 for £210.00 with free shipping. Alternatively, refurbished units are available online at various prices. After installing it, you need to configure it by going into diagnostics/configuration and then checking on the vehicle. Operation completed successfully.
