But might be worth reading some of the negative reviews and the ELM 327 wiki page as this is a newer car.
This item, like most cheap OBD scanners using "elm 327" in their name are counterfits running on very old, outdated firmware that won't work with more modern cars, and can not make use of any the modern OBD protocols, despite false claims that they do.
These devices are named "elm 327" as they are based on 'elm electronics' original OBD protocol interpreter ICs', and are counterfiet clones of this firmware.
Elm accidentally released a version of their ICs without the firmware protected, and effectively had their firmware stolen and then put in cloned devices such as these. This was version 1.0 (they are now on v 2.2) and as per Wikipedia article on elm327, most fakes claim they are using "V1.5" (like this listing) despite there never being a version 1.5 ever being released by elm.
Don't waste your money on this. Use the "elm327 identifier" app, which will test various AT codes if you don't believe me, it will fail to do any of the modern ones and I doubt all the pins are even connected on this device.
Most people are plugging this in their car, reading the car temperature, revs and so on which are basic reporting from original OBD protocol and thinking this device "Works", and yet are lacking out on substantial features, scans that won't return genuine issues because feature isn't implimented!
You won't get a genuine, modern OBD scanner for this cheap. Genuine ones are towards the £100 mark.
If your car was built in the last 10 years you're missing features! Regardless, the v1 that got stolen had bugs in it toohttps://en.wikipedia.org/wiki/ELM327#Pirate_clones
Edit: I'm still tempted, as my car is 20 years old...

Further to this, I got an bluetooth ODB2 connector from amazon (Torque Pro), with the Torque app. Mostly got it so I could have charts flying around as I drove, but it's a really cheap way to show all the engine codes and what they mean (including clearing them if you want).
You can then do a bit of pre-garage googling. It was about a tenner all in.
