What to know before buying

Listing details to confirm

The listing says basic OBD2 features are available without payment, while describing advanced diagnostics, service tools, live data and customisations as subscription features. A separate FAQ lists free live data and emissions checks, so which functions are free is inconsistent. Compatibility and available functions depend on the vehicle. The listing also gives generic OBD2 compatibility for any 1996+ US vehicle, which may not apply to UK cars.

Frequently asked questions

Do advanced Carista EVO features require a subscription?

Yes. The listing says advanced diagnostics, service tools and customisations require a paid Carista app plan. It describes basic OBD2 features as available upon purchase, but its statements about whether live data is free conflict, so check the current app feature list.

Which phones does Carista EVO support?

The listing names Android and iOS and describes a Bluetooth connection.

Will it work with my car?

The listing names certain makes and models, but does not establish compatibility for every vehicle in those ranges. Check compatibility for your specific vehicle in the app before buying.

Does the adapter need batteries?

The listing says it draws power from the OBD2 port and does not need batteries. It also advises unplugging it when not in use to avoid parasitic drain.
