Alfaobd is pretty common here on the forum and an obd mx+ wireless adapter

For a 25 you will need a bypass cable

AFAIK, the 2025s are still a no-go for AlfaOBD.

I read nothing but problems with the 2025 and 2026 models. I understand those with issues go to forums for help but damn..... . All over Facebook groups and Reddit groups. Many with not maybe miles at all and some still in warranty window.
Hope yours is a good one. Don't know what the big change is asside from the engine.

Mine is a 2023
