GuiDia

About this app

GuiDia allows you to not only read out diagnostic trouble codes free of charge, the app also provides you with fast and reliable support for all diagnostic steps to get you right to the source of the fault. It functions independently of the vehicle manufacturer and primarily uses the manufacturer-independent P0 diagnostic trouble codes for diagnostics. The focus is on vehicles produced between 2008 and 2016 – both gas and diesel powered. You can decide whether to read out the diagnostic trouble codes conveniently with an OBD adapter or enter them yourself.

The objective of GuiDia is to guide you to the actual cause of the fault faster and more reliably – step by step with visualized instructions in your language. This means you can make significant savings instead of spending on avoidable repair attempts and unnecessary parts replacements. Thanks to artificial intelligence, GuiDia gets smarter each time it is used, taking you to the source of the fault more quickly all the time.
