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

I’ve been really impressed with the Carista EVO Bluetooth OBD2 Scanner from Carista — it was incredibly easy to set up, paired with my phone in minutes, and the app made everything simple to understand even for a non-expert. I’ve used it to check my car’s overall status, read and clear fault codes, and keep an eye on potential issues before they turn into bigger problems, which gives real peace of mind. I also liked how straightforward it was to change certain vehicle settings and customisations right from the app, something I couldn’t do with basic scanners before. The Bluetooth connection has been stable and reliable, and the whole experience feels polished and user-friendly rather than technical or confusing. It’s a great tool for everyday drivers who want more insight into their car without going to a garage for every little warning light — highly recommended, just make sure you check that your specific car model is supported so you can use all the features.

Having used dealer-level diagnostic and programming software, this device is an absolute must for the enthusiast. It makes complex programming a doddle - what would normally take 30 mins now takes around 3 minutes. Before reading this short review, a couple of must knows - check your vehicle is compatible before buying on the CARISTA website. For example, this device only had basic functions on a 2015 Mercedes E Class. But it had full functionality on a 2008 BMW 3 series, and also a 2018 VW Polo. For those who think this is the 'ONE STOP SHOP' of diagnostic scanners out there - it comes pretty damn close. It's plug and play, no need to connect to wifi (iOS ELM 327), simply launch the app and it connects to the Carista seamlessly every time. Picture shows activation of ‘Real-time MPG’ on an e90 BMW M3 which can improve your driving style helping you to understand how to save fuel when not driving these cars at their full potential. This option was activated in 2 minutes on the CARISTA and not normally activated from the factory on these vehicles. A quick lesson in On Board Diagnostics: Most cars have several 'modules' (ECU's) which control all functions of the vehicle. Do a google search of 'BMW Module Tree' to see what this looks like on paper. Your £5 - £50 scanners can normally interrogate ONLY THE ENGINE (ECU) module, as this is most commonly responsible for the 'Check Engine' light. A £50 scanner might give you live data of engine parameters with graphing etc. for fault finding, and the £5 scanner will simply give you a fault code. These scanners rarely let you code/program anything on the vehicle. The more expensive scanners £50 - £250 work to interrogate additional modules including ABS, Airbag, Transmission etc. which can also cause the Check Engine light to illuminate. Decent scanners have better compatibility with a wider range of vehicles and some explanation of the fault codes built in (google is normally best for interpretation of codes anyway). These are still 'scanners' and permit very limit coding/programming to the vehicle, unless otherwise stated (steering angle sensor, battery programming, TPMS reset etc. are common features built-in). These scanners work for 50% of vehicle problems. The expensive £400+ scanners usually allow interrogation of all vehicle modules, or atleast as many as are compatible with the device. Common faults often occur in auxiliary modules such as Footwell, Light, Car Access System, Radio etc. which normally only dealer-level OEM software can interpret, interrogate and program properly. These scanners offer varying levels of compatibility, but work for 90% of problems on cars, most independent garages use these and they often require some sort of subscription service. The amazing thing about the Carista is that it is actually interrogating several modules in the car which normally only the £400 scanners would do. In order to do complex customisations it needs access to read and write to these auxiliary modules. To enable features like real-time mpg, driver door unlock on one-click, and increasing brightness of rear lights would normally require 30 mins of downloading module data to a laptop, interpreting through dealer-level software, editing string values, and re-uploading to the module, all in a careful and timely manner. The Carista takes care of this whole process and does the coding in seconds. It's quite unbelievable (although not the first on the market to do this, it seems to be the first multi-vehicle, cross-compatible device). So in having access to all vehicle modules, Carista is able to report back detailed error codes within these modules. The caveat is it only works if the Carista scanner is compatible with the vehicle. A 2015 Mercedes E Class W212 with the 'Auxiliary Battery Malfunction' error was not picked up by the Carista, nor was it recognised by a trusty £200 scanner. It's likely that to read this error in more detail, a £400+ scanner would be required, or dealer-level software with a USB cable and laptop. The 2007-2013 BMW 3 Series E9x vehicles are very well covered, as are VAG group vehicles. Compatibility seems to be improving regularly and is already very good for a device at this price. Carista have a Beta Test Team which are constantly working to add functionality and compatibility. You can join this team from their website. All in all, an excellent little scanner, worth every penny. Hints for use: Keep a record of the customisations you carry out. Carry out customisations one-at-a-time with the IGNITION ON but ENGINE OFF. Ensure your car battery is in good order, if in doubt connect a battery charger if doing a long session as a battery failure during programming can be fatal for the module. End all other apps on your phone/tablet and disconnect all other bluetooth devices. Do not operate things in the vehicle whilst coding/diagnosing/using the Carista, modules should be idle during read/write. Opening / closing doors and windows and operating the radio can affect coding. WARNING on BMW E9x vehicles: Activating the 'Engine can be started only when car is in Neutral/Park' is for AUTOMATIC MODELS only. Activating this customisation on a Manual vehicle will prevent it from starting! - There are a number of issues like this, where the customisation needs to be carefully considered before activation. Wish list for future updates: More powerful diagnostics - adaptations, activation of ABS pump for bleeding, O2 sensor testing, live data streaming, sensor readouts, graphing, etc. Save/Restore feature - after making some customisation 'mistakes' you have to go back and undo those customisations by guessing. Increased vehicle compatibility list, especially Mercedes and other popular cars. Also fixing functionality with other diagnostic apps which are classed as compatible, could not get these to recognise and connect to the Carista. Also, some information on each customisation, quite often it's a case of guessing what each thing does. Grouping customisations into a 'custom list' would also be handy. For example, you don't need to look at customisations relevant to the sunroof when the vehicle does not have one. Thanks Carista for a device that everyone has been waiting for. Enjoy your car, your way!

I use the Carista Evo regularly to monitor DPF Regens which occur every 200 - 250 miles. Carista enables me to tailor my journey to ensure completion of the process. The downsides - some issues with connection, resulting in frustration, but after some unplugging and rebooting it comes back online. Also had a couple of occurrences where it won’t clear a fault, but reassuring to be able to diagnose any issues. I have not embarked on the customisation features. Overall, a good product and worthwhile purchase, though subscription is expensive.

The Carista EVO OBD2 scanner is an excellent tool for anyone who wants to understand their car better or save time on diagnostics. Pairing via Bluetooth is effortless, and the app connects quickly without any fuss. Within seconds, it scans the vehicle and provides clear, detailed information about any fault codes or potential issues. What’s great is how user-friendly it is even if you’re not a mechanic, the layout and explanations make it easy to follow. The ability to customise certain vehicle settings is a nice bonus, and the live data readings are accurate and responsive. It’s compact, well built, and works seamlessly with both Android and iOS. Overall, it’s a reliable, professional-grade diagnostic tool that’s simple enough for everyday drivers but powerful enough for enthusiasts.

Having used many diagnostic tools for years, including the USB types such as OBD11, I rate this higher for regular users as it is not pay per option, but subscription based. I also find the GUI easier to use than OBD11 and it seems quicker and more responsive. When I'm not using it with the Carista app, it can also be used as a dongle to connect to my android phone running VAG DPF app (other diagnostic apps will work in same way) so I can keep a real time eye on my DPF and its regeneration. Very easy to setup and I've recommended one to friends due to its easy ability to read and reset codes and quite easily interpret live data

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!

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.

センサーのエラーコードを見たり、消したりするくらいには十分 車種によって出来ることには、差があると思うが、コーティングも一応出来る。 悪くはないかな

I’m very satisfied with Carista Evo. It arrived one day earlier than expected. Connects flawlessly with my car and operates like a charm. I tested it with some of our company’s cars also which are mostly from the VAG group - no issues. - it reads the errors, clears old records - works as a charm. I recommend it to anyone who wants to understand and take a better care for its car.
