## Description

From the brand

Review: Fantastic! Works best on 2007-2013 vehicles. Check compatibility before buying! - 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!
Review: Amazing car diagnostic tool for everyday use. - 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.

### ⭐⭐⭐⭐ Perfect for the job. Well designed and a good quality feel to the construction.
*by C***1 on 24 April 2016*

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.
