CARISTAOBD - Bluetooth OBD2 Scanner - Car Scanner Diagnostic Tool and Code Reader with Access to Diagnostics, Customizations, Service Tools, and Live Data

Small enough to leave in glovebox. Ignore subscription costs. I put one month on when I need it. Reset airbag light for MOT. Fit rear pads with electric parking brake. Fit fuel filter and prime HP fuel pump properly. DPF reset and diagnostics. ABS sensor diagnostic. All of this I have done with this simple to use dongle type OBD reader. Saved thousands on labour and garage costs. VW passat b7 2012. Using once pays for itself. Also can turn on or off things like daytime running lights, indicator 1 flash or 3 on touch and many more. I recommend this Catista unit to everyone

This is an amazing app if yoir car is newer and has the correct systems to be utilised, this has saved me and my family plenty of money, the diagnostic is accurate when used, I have been able to change settings on my car. There are 2 ways to use the app, one is free for basic diagnostic which is OK does the job to give codes. The other is to pay a membership and utilise the full app, the yearly price is less than one diagnostic at a garage, the extra features are good. Works on my bmw, audi and my brothers VW. Car list is growing alot.

Carista is probably one of the better known home diagnostic and 'customising' OBD tools on the market.I had access to one in the past and this helped in my decision to purchase it.The plug-in reader is small and neat - it tucks away in the OBD port in the car, and you could leave it plugged in if you wish.You can only connect through the Carista app on your smartphone/device and you don't need to Bluetooth sync it.The readouts and information are good - it's much more in depth than a basic plug-in OBDII reader, and gives you details on faults in the electrical systems, infotainment, transmission, etc. as well as the general engine systems.Where your vehicle allows you can customise some parts of the general vehicle functionality, such as convenience systems, light operation, locking acknowledgements, etc.I added an alarm 'bip' when I lock the car.Sadly you have to pay a subscription to access all features after the one-month free trial (which was priced at £46.99 a year when I purchased this unit in January 2021). You have to sign up to this subscription before you can access any features, but you can cancel at the end of your one month trial.Overall a good system and I would recommend it, but might not be worth the subscription price if you're not going to use all the features.

Ok for basic use on basic fault finding,

Very useful only set back is the yearly subscription

It's amazing to think that something so small and cheap can be so powerful. After locating my OBD2 port and downloading the app, I was able to diagnose and reset faults in my car and enable all sorts of additional features. There is no programming or technical knowledge required at all - the adapter connects to the app on your phone by Bluetooth and identifies your car automatically. It knows what options it has for your car, so it then presents a list of options with simple ON/OFF (or similar) selections that are appropriate to your car. For example, I was able to enable cornering lights on my car simply by selecting ON from the option for it (the car's software already has the feature but it's disabled by the manufacturer so they can enable it in other countries or on higher spec models). Other features I've enabled are that the hazard lights flash when braking sharply; the car's headlights stay on for a few moments after leaving the car at night; I have additional options in the car's menus to enable/disable the daytime running lights and other features that weren't previously there; when closing the electric windows with the remote control, the car's indicators flash when all windows have closed completely; etc. The specific options will certainly be different for each particular car so your best bet would be to check their website for which cars are supported. My colleagues also enabled various features in their cars and their friends cars using the same adapter and everyone has been impressed with this!
