Carista EVO - Bluetooth OBD2 Scanner - Car Diagnostic Tool & Code Reader with Access to Diagnostics, Customizations, Service Tools & Live Data (Subscription Required)

Brilliant. Detected all faults and cleared them (Although that cost me an extra £15) but worth it! Very happy deffo keeping.

Fast, stable Bluetooth connection — noticeably quicker than many generic ELM327 adapters. Advanced features — diagnostics, live data, service tools, and hidden settings (coding). Works very well when paired with the Carista app. Subscription requiredM basic code reading is free, but all the “good stuff” (customizations, deeper diagnostics) needs a paid plan.

Firstly this arrives in a nicely constructed case. Removing the device from the packaging and it is immediately obvious that the device is well constructed. It feels like a premium device. This does the job nicely and I have tested on a number of vehicles including Ford, Renault and BMW. Its worked on every occasion showing up the faults. On the vehicles I have tested on you can easily plug the device in, replace the interior trim and leave it there. It's small footprints makes it ideal to just leave in place. One minor draw back to this is sometimes its a little difficult to get it back out again. I have only tested the device on iOS. The device is bluetooth and works with the Carista App and OBD Fusion as advertised. Apples restrictions on bluetooth means that these are the only two apps I am aware of that it works on. The adapter is really simple to use, simply plug it into the OBD2 socket of your vehicle, launch your preferred app and press connect. Hey presto you are connected to the car. There is no requirement to pair the device to your iPhone. (as I spent about 30mins trying to do) it just simply connects. I have successfully been able to read the fault code on my partners car and quickly identified the faulty part. I'm now just waiting for a new part before I fully reset the code. I would rate this five stars if only it was compatible with more iOS apps. That is slightly unfair as that's not entirely the manufactures fault. My advice before buying this device would be to research the App that would be most suitable for your car. Many cars have advanced diagnostics and you ideally need to find the best App first then decide on your OBD2 device. If your car is compatible with Carista or OBD fusion then I would throughly recommend this product. Having used both apps I would recommend the OBD fusion App. It is well designed and easy to use. Not only allowing the user to read and reset fault codes you can get live time information from a range of the sensors as the engine is running. The OBD app also allows you to buy advanced diagnostics for certain makes and models of vehicles. I have not been able to test that yet as sadly my vehicle is too new to be supported.

I’ve used this Carista OBD2 scanner many times, especially before taking the car for its MOT, and it’s been really helpful for checking fault codes and monitoring the car beforehand. Setup is simple through Bluetooth and the app connects quickly without complicated installation. The scanner itself is compact and easy to keep in the glovebox when needed. One of the best features is being able to view live data and run basic diagnosis checks directly from a phone. It helped us identify smaller issues early and reset certain warning lights before booking repairs. The app is easy to navigate even without advanced mechanical knowledge, and compatibility with our vehicle has been very good so far. For the price, I think it offers strong value for money considering how much information and functionality it provides. The only small downside is that some advanced features require a subscription within the app, so that’s worth knowing in advance. Overall, a practical, easy to use and reliable diagnostic tool for everyday drivers and MOT preparation.

This is a great little device, although you have to sign up and pay a fee for the full data its worth it rather than paying a garage for the same amount. This is far better than a basic obd reader and worth the extra money This reader gave me live diagnostics and which gave me exactly what I needed, to find and rectify the fault in my car.

I bought this to diagnose an error showing on my car (VW Polo 2016). I previously tried using a cheap (£10) diagnostic reader which only showed me 1 error code. When I plugged in the Carista, it instantly showed me 3 errors and I was able to replace the faulty sensor and then clear the errors using the Carista. I have also used it to change quite a few other settings on my car. I have used it to enable an engineering menu which then allowed me to activate CarPlay (was previously locked behind dealer code). I have also used it to enable the reversing camera function on my head unit and I have installed a reversing camera which now shows on my screen. I have also changed quite a few other settings like auto locking / unlocking doors and disabling some warning dings etc. Great bit of kit! I was a bit hesitant about the subscription price, but given how much it's allowed me to do I'm very happy with it!

Personally I think this overpriced paperweight deserves 0 stars, but we must have some moral respect for products on here. I purchased the original adapter back in June 2024. Only for them to lock all the features behind a paywall OR if you purchase the EVO variant. Was prepared to spend the few extra pennies on the Evo model in October 2024. Worked great when I got it, all diagnostics were free and easy to understand, and clear. I used it throughout 2025, even paying for a month so I could customise my car a little bit (albeit the features are no where near as detailed as OBDEleven) I’ve just gone to use the product today and… low and behold, NOTHING is free anymore for my vehicle. Everything is now behind a paywall for a mere £60 per year, on top of the £50 product. This is absurd and makes this product completely useless without a subscription. You aren’t using anything of theirs for them to charge, so I’m unsure why it’s all subscription based. Contacted Carista customer service and they defend their company by saying “advanced features require subscription” despite their website saying otherwise. Amazon have allowed me to return the product for a full refund. STAY WAY CLEAR OF THIS PRODUCT

The app is easy to use and the quality of the product is good. Fault clearing and error code reading is also good. The unlocking of additional functions on your vehicles not so great. Seems as though the system is not up to date with later vehicles. I only purchased to turn off annoying alerts on a 2024 Range Rover and a 2026 VW Amarok. It doesn’t work on either. Only upgrades are for day running lights. Disappointed when compared to the marketing.

Tried OBD Eleven before and it failed completely, despite promises for Toyota and Lexus group couldn't do anything but to see correct model and basic car info. Bravo Carista, well done! Works well for 2023 Lexus RZ450e. Lots of options can be customized and upgraded. 2024 Renault Austral not recognized yet, but hopefully it will be upgraded in near future. Good job lads, GOOD JOB!

There are lots of great reviews on this item, so I encourage you to research what IS and what IS NOT included "for free" with this device. I wanted to focus on what this is an absolutely ESSENTIAL tool to buy if you are looking to buy a used Audi S4 (or any other vehicle that this unit applies to that has a launch control counter). Audi S4s with the automatic transmission have a launch control feature; basically the engine revs and the automatic clutch gets dumped, and you shoot off like a rocket. Well, this is quite hard on the vehicle, and as a result Audi limits the number of launches to 200 maximum for the life of the vehicle (at least this is the case for the 2010-2016 Audi S4 range). So when buying a used S4, one of THE best ways to verify if the car has lived a hard life working the local drag strips is to see just how many times the vehicle has been launched in this manner. Enter the Carista device! All you need to do is download the app, plug in the box into the OBD port, and you immediately will have a very quick and easy way to check the number of launches. Best of all - you do NOT need to set up an account, fill out any forms, or buy anything whatsoever; this is default functionality that is completely free and requires NO additional setup or hassle. I wound up buying a used S4 with only 7 launches. Note that I originally went with the XTool VAG401 handheld scanning device, and I hate it. It is incredibly slow, menus are completely wrong in many cases, and after struggling for about 3 hours, I gave up on finding the launch control counter (yes, I fully researched VCDS menus and code blocks, downloaded the latest update for the tool, and had no luck). The Carista device immediately could tell me that there were NO trouble codes, and gave me an immediate answer on the number of launches. So yes, there are tons of detailed settings that Carista can help you easily adjust, and many of these functions do require you to pay money (at least beyond the initial free 30 days), BUT if you want a really easy to use device that can tell you if there are any trouble codes, AND give you launch control counter information, all INCLUDED FOR FREE permanently as part of the device, then do yourself a favor and snag a Carista device!

Wszystko super, szkoda że aby mieć dostęp do wszystkich funkcji trzeba subskrybować aplikację, ale i tak fajne rozwiązanie. 1 miesiąc jest okresu próbnego, wiec można sobie włączyć w aucie wszystkie potrzebne funkcje a później w razie potrzeby wykupić dostęp do appki zależnie od potrzeby. Jedną z rzeczy które ja odblokowałem w swoim aucie to np. doświetlanie zakrętów. Ogólnie polecam !

La verdad es un buen equipo yo considero en una gama media eso si tienes que pagar una anualidad para tener acceso a todos los sistemas.

Fácil de usar. Realmente lo compré para personalizar el tablero de instrumentos para un Jetta MK6 2018 y una Tiguan Sport&Style 2013, en ambos funcionó. Aparte probé el scanner en una Frontier SV 2012 y me arrojó varios testigos y códigos por reparar, muy bien. Puedes usar la prueba gratis del mes y cancelar la renovación dos días antes, así le hice yo en un iPhone; lo que realmenre está caro es la suscripción.
