LAUNCH OBD2 Scanner X431 PRO3 ACE Diagnostic Tool with Bluetooth DBS car VII, Topology Mapping, Online Coding, CANFD&DoIP, 55+ Services, SGW Function, V.A.G. Guided Function

I’ve been using the LAUNCH X431 PRO3 ACE for a few weeks now, and I can confidently say this is one of the best investments I’ve made in automotive diagnostics. Whether you're a seasoned mechanic or a serious DIY enthusiast, this tool delivers exceptional performance, depth, and ease of use. ✅ Comprehensive Vehicle Coverage – The scanner supports a wide range of vehicles (both domestic and international), including the latest 2023/2024 models. It connects effortlessly and reads almost every module—engine, transmission, ABS, SRS, and more. ✅ Advanced Diagnostics – This tool goes way beyond basic OBD2 functions. With features like bi-directional control, ECU coding, and active tests, I’ve been able to perform functions that were previously only available with OEM-level tools. ✅ Fast and Intuitive – The large touchscreen, Android-based interface, and fast processor make navigation smooth and responsive. It boots quickly, and the user interface is clean and easy to understand. ✅ Wireless Convenience – The included VCI allows for Bluetooth connection, eliminating cables and making it super convenient to walk around the vehicle while testing. ✅ Frequent Software Updates – LAUNCH provides regular updates, which is great for staying current with new vehicle models and features. The 2 years of free updates is a huge plus. ✅ Extra Features – I love the diagnostic report generation and remote diagnostics capability. It’s great for sharing detailed results with customers or colleagues.

The after-sales support provided is truly excellent, offering prompt and helpful assistance whenever needed. I would confidently recommend this product. This diagnostic kit covers all the essential functions you would expect, and more. It also includes an OBD cable set for vehicles that do not have the standard 16-pin connector, allowing compatibility with most cars manufactured from 1996 onwards. The system is very user-friendly — in most cases, just three simple clicks will generate a full vehicle report and diagnosis. There is also a convenient feature to search error codes online directly from the device. Connection is quick and reliable via Bluetooth, eliminating the need for cables and giving you the freedom to move around the vehicle while checking lights and other functions without hassle. It’s an outstanding kit that I’ve already recommended to friends and family. For the best experience, I highly suggest purchasing through this seller, as their customer support is truly second to none.

A very clever scanner that will do everything very fast and many other operations with the correct add on hardware, ie camera calibrations etc. The topology option reminds me a lot of ODIS and in my opinion it’s a great way to view all the modules being scanned in real time. It’s a very easy scanner to navigate and user friendly. This Launch does so much and I would definitely recommend this

Not a cheap device for sure, but considering it does EVERYTHING you would expect a high end diagnostic scanner to do, you really do get what you pay for. It even programs new keys for you And has the software to diagnose most modern cars using newer protocalls I doubt very much there is a better packed scanner on the market for the money, normally this kind of tech would cost well over £1500 And the fact I can now perfrom my own services and reset the annoying service reminders is a massive bonus So at £799 this is a bit of a bargain! Highly recommended for the professional and DIY mechanic too

Good tech too many addons you have to pay for on the set up, should be included in the price, also struggles with older i.e 2006 connections to the ECU.

Bought this for the second time, unlike my first one got stolen.... but luckily they been able to disable the other diagnostic machine. I could have bought another one for less, but honestly this machine does literally a lot of things. Worth the money. Top fault detection. Easy to use.

I bought this in 2024 and has done a great job until today in August 2025, the updates have been regular but today the updates must have caused a problem of freezing everything when doing a diagnostic check on my 2006 Range Rover. The only way to solve it was to do a factory reset, reinstall the software and log into the account to get it all up and working! That was the trouble I had forgotten my login details! Simple I thought just register again using the same email address oh how I was wrong! Launch require the serial numbers from the Tablet and the Vci then an activation number which I still have. The Vci is registered to my old account and would not let me register it to the new account, now for the bad bit. Launch are not answering my messages via thier support chat and requests for help from several other communication channels and thier website is a nightmare to navigate past mainly sales pages!!!! ☆☆☆Update☆☆☆ 24hrs later Launch got back to me and gave me my original sign in details. Live chat was none existent when I tried it all day! To be blunt backup is not great. It worked really well until this!

The launch was a very good professional tool as it allowed me to code in my bmw headlights. However when we tried with AUTEL it didn’t work and kept crashing. Very smooth and accurate system. Highly recommended

Fenomenal

Le Launch X431 Pro3 Ace est un outil de diagnostic qui inspire confiance dès la prise en main. L’écran est clair et réactif, et l’interface paraît intuitive. La couverture de nombreux modèles de véhicules est un vrai plus pour les professionnels comme pour les particuliers exigeants. C’est un appareil moderne et complet, qui semble conçu pour durer. Je suis satisfait de mon choix et je pense qu’il sera très utile dans le temps. Un produit que je conseil fortement pour le mécanisme de la voiture.

Hi, Perfect device to diagnos the cars. comes with Bluetooth connection and 2years of free update....Highly recommended

Very very good !

Ich muss sagen, ich bin absolut begeistert vom LAUNCH X431 PRO3 ACE! Ich hatte vor Kurzem ein hartnäckiges Problem mit meinem Auto, bei dem die Werkstatt schon fast das Motorsteuergerät tauschen wollte – Kostenpunkt jenseits von Gut und Böse. Aber ich wollte es genau wissen und habe mir dieses Diagnosegerät zugelegt. Und was soll ich sagen? Es war die beste Entscheidung! Mit dem PRO3 ACE konnte ich erstmal ganz klar feststellen, dass das Motorsteuergerät selbst einwandfrei funktioniert. Das war schon mal eine riesige Erleichterung. Der eigentliche Clou kam aber dann: Dank der bidirektionalen Steuerung konnte ich einzelne Bauteile direkt vom Gerät aus ansteuern und deren Signale prüfen. So konnte ich Schritt für Schritt die Verkabelung durchgehen und habe tatsächlich einen Kabelbruch nach dem Steuergerät entdeckt! Ohne diese Funktion hätte ich das niemals so schnell und präzise lokalisieren können. Nachdem der Kabelbruch repariert war, lief alles wieder perfekt. Dieses Gerät hat mir nicht nur Hunderte, wenn nicht Tausende von Euro gespart, sondern auch unzählige Stunden an Frustration. Die Bedienung ist intuitiv, das Display groß und klar, und die Geschwindigkeit ist top. Wer wirklich tief in die Fahrzeugdiagnose einsteigen und Probleme selbst lösen will, für den ist der LAUNCH X431 PRO3 ACE ein absolutes Muss. Das ist keine Spielerei, sondern ein echtes Profi-Werkzeug, das sich schnell bezahlt macht. 5 Sterne und eine klare Empfehlung von meiner Seite!
