Carista Bluetooth OBD2 Scanner EVO — Car diagnostic adapter with live data & customization

Carista EVO is a Bluetooth OBD2 adapter that turns your phone into a car diagnostics, customization and live-data tool when paired with the Carista App (subscription required for advanced features).

The Carista EVO adapter plugs into your vehicle’s OBD2 port and connects wirelessly to the Carista mobile app on Android or iOS. Out of the box it provides basic fault-code reading and clearing; subscribing to Carista unlocks deeper manufacturer-specific diagnostics, service functions, coding/customization and live sensor readouts. The device is compact, works with a wide range of makes and models, and aims to reduce time and cost for routine troubleshooting and DIY maintenance.

What diagnostics and service tasks can Carista EVO perform?

With the Carista App subscription, EVO exposes both generic OBD2 codes and many brand-specific systems for supported vehicles. That includes reading diagnostic trouble codes, accessing freeze-frame data, and running common service resets for maintenance items.

• Read and clear engine and system fault codes, with freeze-frame snapshots
• Perform service functions like oil or inspection resets where supported
• View manufacturer-specific modules when available through the app

How does Carista EVO help me customize my vehicle?

For compatible cars, Carista EVO plus a paid Carista App plan lets you change user-facing settings locked by the manufacturer. This can enable or alter convenience features without hardware changes, using officially licensed access for many Volkswagen Group models.

• Toggle convenience options such as lighting, locking behavior, and chimes
• Apply VAG-licensed customizations for supported Volkswagen Group vehicles
• Save and revert settings through the app to experiment safely

Which cars are supported and how broad is compatibility?

Carista publishes compatibility by make and model; EVO covers numerous brands across European, Asian and American manufacturers. Compatibility varies by year and model, and some advanced features are available only for specific vehicles, so always check the Carista App or website for an exact fit list before purchase.

• Works with many Audi, BMW, Ford, Honda, Hyundai, Kia, Mazda, Nissan, Toyota, Volkswagen, Volvo and more
• Advanced, brand-specific tools may be limited by model year or module type
• Basic OBD2 reading works across virtually all OBD2-compliant vehicles

How does the subscription model work and what do I get?

The adapter activates basic features immediately, while advanced diagnostics and customization require a paid Carista App plan. You can choose short-term access for a single project or an annual plan for ongoing monitoring and maintenance work.

• Basic fault-code reading enabled at purchase, no subscription needed for that function
• Monthly and yearly subscription options unlock live data, service tools and coding
• Use one Carista EVO on multiple compatible vehicles tied to your app account

Who is this for: Carista EVO suits car owners, DIY mechanics and small garages wanting a compact, phone-driven OBD2 solution. If you need quick fault diagnosis, want to perform routine service resets yourself, or enjoy safely adjusting convenience settings on supported makes, EVO plus the Carista App is a practical, low-cost alternative to dealer visits. If you require deep manufacturer coverage for an uncommon model or commercial vehicle, verify compatibility first and consider subscription access to unlock the full feature set.
