Fantastic Kit, very strong unit and able to everything you need for diagnostic work
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.

Top Seller and a really good Diagnostic tool
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.

Brilliant Tool and has all Functions you can ask for
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

Good investment
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.

Really impressive piece of kit. Only used on 3 vehicles so far and it fulfilled all requirements.
Really clean and clear display. The Topology screen is particularly useful when carrying out the initial investigations. Reasonable array of functions presented well with good descriptive assistance attached. could have done with a slightly longer cable on the VCI Receiver so it could be placed on top of the dash instead of, mostly, on the floor. Unable to comment on battery life, etc, as it is all still new to me, but functionally, it beats most of my previous Analysers already. I don't think I'll regret purchasing it.

Probably The Last Diagnostic Scanner You'll Ever Buy
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

Arrived in a big box
Takes a while to set up but all went well. Tried it on my Ford fiesta and worked really well. Still getting used to it but must say it seems to do a lot. Good price for this scanner.

Don't expect immediate support from Launch.
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!

Hi, I am a Diagnostic proffesional and have a lot of aftermarket and OEM tools. (De Rooij Diagnose) I have used the Launch for over a week now. It is a pleasure to work with. Pretty fast to scan vehicles. To my suprise I was able and get acces to 2024 VW ID5. But also one of the few tools that I have that was able and do a transmission calibration on a 2009 Iveco Daily. Also a Front camera calibration on a 2022 BMW 5-series was not a problem. Have not used online coding functionality. But I did see I could online program and code the front camera on the BMW. Connection with the bluetooth interface is fast. Automatic ID vehicles (if supported) works fast. And the tree structure system scan is great (see the video) Tablet battery lasts pretty long (have not charged it yet) After a few hours of use. A wide variety of brands are supported. Additional modules for extra functionality can be purchased from in the application Looking up dtc's is sometimes slow. But that is not a big issue.

para nada es intuitiva, y no te permite hacer todo lo que dice

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.

This was purchased to replace my 2019 version of the same scanner. After years of use I decided it was time to upgrade. The old unit still did the job but was getting slow simply from being so "old", this new one was like night and day. The GUI had mostly the same feel as the old one so I was happy to be able to use it right away with no learning curve. The scanner arrived with two cases. one for the scanner itself which was nice and another for a huge amount of adapters for older vehicles and some that I honestly don't know what they are used for but it's nice to know they are there if I ever find myself needing them but also nice to not have them in the same case as the tablet so I'm not carrying them around all of the time. Operational it works exactly how one would expect, no lagging other than on some manufactures in which case that's the OEMs issue and they lag no matter what scanner is used. The tablet itself feels nice and sturdy and the kickstand on the back is a welcomed addition to the old unit I had. One really nice thing it the ability to add interfaces in the future. I plan to add on the Scopebox when my oscilloscope from another vendor is ready to be replaced.
