Question: Does this scan tool allow you to do maintenance reminders based on mileage?
Answer: No, it doesn’t. This is because there is no such functionality in the app at the moment. But what the Bluetooth adapter does is reset your service and inspection indicators on supported Audi or VW car models. Also, you should note that it doesn’t adjust the intervals but it just resets the counters to zero. For instance, it is vital when you’ve just performed the relevant service. To get all these features, you have to buy a professional scanner like Autel TS601.

Question: Does this scan tool feature a specific refresh rate?
Answer: No, it doesn’t. Some users say it has a refresh rate of 30Hz, while others say it has 3-5 Hz refresh rate. But this solely depends on what you’re performing, the type of app you’re using, and the type of vehicle. Since the Carista app doesn’t provide live data, there is no official metrics on the refresh rate.


You can be 100% sure that this device will work with the Carista OBD2 app on Android and iOS (iPhone/iPad/iPod Touch excluding iPad 2). OBD2 is capable to read codes and reset for free (this suits ALL 1996 and newer brands and models (US)) It can also do diagnostics (ABS, airbag, etc.) that costs money. Also, it can establish vehicle settings for models of Audi, BMW, Lexus, Mini, Scion, Toyota, VW (supplementary in-app acquisition required). This adapter is reconcilable with other ELM327-based apps on Android and OBD Fusion on iOS. Utilizes Bluetooth 4.0 LE on iOS, reconcilable with Bluetooth 2.1 on Android. Needs iOS 8 or Android 2.3 or newer. It doesn’t work with iPad 2. But you need to purchase the app separately as it is not free like Launch CRP129 automotive diagnostic scan tool.


You will be able to see every little detail about the electronics in your car by using Carista app with the Carista OBD2 adapter. You will not have to worry about errors and warning lights on your dashboard because you will have the ability to check what’s wrong just by yourself. Another great thing about this device is that you can do an electronic diagnostics with it. By doing that you’ll save your money. Verify and reset OBD2 and brand-specific error codes in all ECUs in the car, this involves ABS, airbag, etc. Common OBD2 scanner apps cannot approach those modules, but Carista definitely can do it!

IMPORTANT: It is not a professional diagnostics tool. Common OBD2 diagnostics (engine, transmission) will not cost a thing in the Carista app, but you will have to pay for brand-specific diagnostics (ABS, airbag, etc.) The specific diagnostics are only available on particular models by Audi, BMW, Lexus, Mini, Scion, Toyota and VW.

More complex diagnostic in the Carista app is only reconcilable with particular vehicle models by Audi, BMW, Lexus, Mini, Scion, Subaru, Toyota and VW.

The Carista OBD adapter is reconcilable with these apps:

  • Carista OBD2 app on iOS and Android

  • Bluetooth obd2 scanner – no wires
  • Simple to adjust car settings

  • After buying the adapter you have to spend some dollars for the Pro app to make corrections
  • It can have difficulty with the connection (very rare occasions)
  • It cannot check data like vehicle speed, engine RPM, ignition timing (you need to pay for an app called “OBD Fusion”)


Taking care of your car has never been easier! You will be surprised how easy it is to use this OBD2 Adapter. It will help to review and clear engine codes, customize some settings, make electronic diagnostics, etc. There will be no need to search for professional help. The tool offers affordable price even less costly than Bluedriver Obd2 tools. This cheap device will help you to save money, time and leave you satisfied.
