Carista Carista EVO Bluetooth OBD2 Scanner — Compact Diagnostic Tool, Live Data & Customizations (Subscription)

Carista EVO is a Bluetooth OBD2 scanner that reads and clears fault codes, offers live sensor data, and unlocks vehicle customizations when paired with the Carista app and an active subscription.

The Carista EVO combines a compact Bluetooth OBD2 adapter with the Carista mobile app to give drivers basic code-reading out of the box and powerful diagnostic, service and customization tools when you activate a paid plan. It connects to most popular makes and models, provides real-time engine and sensor information, and—where supported—lets you change settings normally reserved for dealers or specialist tools. Note: advanced features require a separate Carista subscription purchased through the app.

What exactly will Carista EVO do for my car?

Out of the box the device performs standard OBD2 scans and clears generic engine codes. With a subscription you gain manufacturer-level diagnostics, deeper freeze-frame data, live parameter streams and permitted customizations for supported vehicles.

• Read & clear check-engine and generic fault codes
• View freeze-frame snapshots and live data streams
• Run service routines and basic maintenance procedures
• Unlock approved manufacturer customizations, incl. VAG options where licensed

How do I use Carista EVO with my phone and car?

Plug the Carista EVO into the vehicle’s OBD2 port, pair it with the Carista app over Bluetooth, then run scans or access features that match your subscription level. The adapter supports both Android and iOS for straightforward setup.

• Install Carista app on Android or iOS and create an account
• Plug the EVO into the vehicle’s OBD2 socket—usually under the dash
• Pair via Bluetooth, then choose free or paid features in-app
• Follow on-screen steps to scan, view live data, or apply settings

Which cars are compatible and what are the limitations?

Carista EVO supports a wide range of manufacturers including Audi, BMW, Toyota, Volkswagen group models and many others. Compatibility depends on make, model year and the specific system you want to access; some advanced brand-specific features require a subscription and may only be available on certain vehicles.

• Works with many European, Asian and American brands (see app for exact models)
• Basic OBD2 functions available on virtually all OBD2-compliant cars
• Manufacturer-specific diagnostics and customizations vary by model/year
• Subscription unlocks advanced features; VAG unlocked where licensed

Will Carista EVO replace my mechanic or dealer visits?

Carista EVO helps you diagnose problems, perform routine service tasks and tailor settings so you can reduce some workshop trips. It doesn’t replace professional repair for complex mechanical issues but can help you know what to fix and whether a dealer visit is necessary.

• Identify trouble codes and monitor live sensor values before a repair
• Perform DIY service actions supported by the app to save time
• Use freeze-frame and live data to confirm intermittent faults
• Rely on professionals for mechanical repairs and warranty work

Who is this for: Carista EVO is aimed at car owners who want more insight into their vehicle—DIY enthusiasts, independent technicians and drivers who prefer to monitor performance, run basic maintenance themselves, or unlock approved custom settings. If you want simple code reads only, the device offers immediate functionality; if you want manufacturer-level access, prepare to subscribe to Carista’s Advanced plans for one month or a year.
