The "CarDiag" application supports motorists from "A" to "Z" in the diagnostic, maintenance and repair of their vehicle independently and cheaply : since the doubt of a problem, the identification of the fault, a diagnostic in simple and easy-to-understand terms and a pollution score, Do-it-yourself auto repairs, tips to buy parts as well as a cost estimation at the nearest mechanic. It also provide a digital maintenance book.


Features :

We have all done the same observation when we take our vehicle to a garage : the mechanic diagnoses possible breakdowns using a dedicated diagnostic tool.

* Have an OBD-II compatible car : OBD-II is compatible with all US vehicle models since 1996, European since 2001 (diesel since 2003), Japanize since 2006.

Ok nice idea, but this sucks. Don't expect anything but the basics for people who don't know jack about mechanics, if you want an advanced auto troubleshooting app this ain't it...for the average joe without any out of the ordinary issues it works good I'm sure.

Hello Becky Leal, Thank you for your feedback. Indeed the CarDiag app is not for professionals. It's dedicated to ordinary people in order to help them understand their breakdowns and assist them either with DIY tutorials for simple repairs or even support at the garage for more complicated breakdowns (price estimate, auto parts, ...)
