If you are looking for a versatile and affordable OBD2 scanner to troubleshoot and fix your car problems, you might want to consider the Topscan OBD2 scanner. This is a wireless Bluetooth device that connects to your phone and allows you to access a wide range of features and functions through the app. You can scan the full system of your car, live data information, send commands to the car’s ECU for active testing, measure the performance of your car and get guidance on how to repair the faults. The device supports most vehicles produced from 1997 to 2022 that comply with the OBDII standard. When I plugged in to a 2003 Audi, I was surprised that it did an auto VIN to read the ECU which my previous dongle didn’t do where I had to search manually. The device is very well-built and sturdy, and it feels like a professional tool. It comes with a one-year free software update, which is a nice bonus. The app is easy to use and navigate, and it provides clear and detailed information. The device and the app work together seamlessly, and the Bluetooth connection is fast and stable using my Samsung Android phone. With the tool it found that the status LED light very useful which showed the power, bluetooth connectivity and a status/communications light. One thing to note is that when you plugin in the device to a vehicle, you will need to download the corresponding vehicles database/packages to the app which did take around 15 minutes on my connection. I think this is a fantastic OBD2 scanner for the money and the features. It does more than my previous dongle I used to use and it helps me save money and time on repairs in the longrun. I would recommend it to anyone who wants to do their own car diagnostics and maintenance or even understand faults that arise on vehicles before they take to a garage. I will keep reviewing this on other makes and models and see how I get on with those. I will update this review where required.

First make sure you understand this comes with basic functions, You need to purchase a yearly Subscription for your needs, Secondly this allows you to do a lot of functions that only a shop can do, So if you are mechanically minded this is a awesome tool, also if you want to do key fobs you can, but you have to purchase that Subscription though the online mall, most other scanners of this type are not bi directional, so for a cheap price and your phone as the monitor and a subscription you go from a man with tools to not paying a shop to diagnose, or do resets of multiple items.

He comprado varios modelos de distintos precios y marcas.... este es el único que va a la perfección y tiene un montón de utilidades y comprobaciones, puestas a cero y demás. producto genial, aunque lleva una suscripción anual y es un poco mas caro que otros, pero merece la pena sobradamente,, cómpralo!!!, no lo dudes, da resultados como en los talleres, me encanta.

Es algo complicado de instalar y de usar las primeras veces. Tiene mucho soporte para muchas marcas de coches, pero si recomiendo ver un tutoríal o algun unboxing para entender varias de las funciones, que incluso con practica a veces es algo complicada pero en general es un gran escáner y tiene soporte y garantía. Consejo revisa si tu teléfono que usaras para conectar el scanner es de 64bits en Android, porque la app no es compatible para sistemas operativos de 32 bits.

PRO 🙂: buon software - compatibilità con Smartphone - molte funzioni disponibili - risolve alcuni problemi. CONTRO 🙃: alcune funzioni possono non essere compatibili con l'auto. Ho usato questo obd per esplorare le funzioni aggiuntive della mia auto, valutare alcuni dati e sbloccare alcune funzioni. È un obd compatto, ho apprezzato il software android, che funziona bene e ben leggibile. Tutto in italiano. 🚘 Ha molte funzioni, l'accesso a molti controlli. Nella mia auto non ho l'accesso a alcune funzionalità perché bloccate dalla centralina, o perché non esistono, ma si possono leggere molti dati e impostazioni nascoste. E posso azzerare alcuni errori. Probabilmente in base all'auto e alla centralina si possono o meno sbloccare determinate funzionalità. Può essere utile per appassionati di meccanica o per chi come me si occupa della manutenzione della propria auto. 👍
