Mechanic & DIYer Reviews
As a mobile mechanic, carrying a bulky tablet was a pain. This wireless VCI is brilliant. The bidirectional controls are incredibly responsive, and forcing a DPF regen on a Transit van took minutes. Best bidirectional obd2 scanner I've bought.
I was sick of the subscription trap with my old LAUNCH tool. Bought this for the lifetime updates and haven't looked back. The portrait mode app is so much easier to use when you're under the bonnet.
Runs full system scans faster than our £1500 workshop unit. The active tests let me command the fuel pump and cooling fans directly to diagnose a tricky electrical fault on a Golf. Highly recommend this obd2 scanner uk kit.
Incredibly powerful tool for the price. The only minor gripe is that the initial software download for all car makes took about 20 minutes on my WiFi, but once it's done, it's lightning fast.
The AI assistant is a game-changer for a serious DIYer like me. Instead of just giving me a cryptic P-code, it actually explained the likely cause of my Audi's misfire. Saved me a costly trip to the dealer.
Fantastic bit of kit. The bidirectional active tests work flawlessly on my BMW. It's so small it's easy to misplace in a messy garage, so definitely use the included lanyard!
Quick Setup Guide
- Download the free Diagnosti app from the Apple App Store or Google Play Store.
- Plug the Diagnosti Pro VCI into your vehicle's 16-pin OBD2 port (usually located under the dashboard).
- Turn the vehicle's ignition to the 'ON' position (do not start the engine).
- Open the app, create your free account, and pair the VCI via Bluetooth.
- Select 'Auto-Detect' to identify your vehicle's VIN and begin a full-system scan.
For too long, the UK automotive diagnostics market has been dominated by legacy brands forcing mechanics and enthusiasts into a corner. You either bought a cheap code reader that couldn't perform active tests, or you spent thousands on bulky tablets from brands like Autel and LAUNCH, only to be hit with £100+ annual subscription fees just to keep them working. At Diagnosti, we knew there had to be a better way.
Founded with the modern UK garage in mind, we stripped away the expensive hardware and the recurring software fees. We engineered a pocket-sized, wireless VCI that connects directly to the supercomputer you already own: your smartphone. By developing a highly stable, native iOS and Android app designed specifically for portrait mode, we've made professional diagnostics faster, more intuitive, and infinitely more portable.
Today, Diagnosti is the go-to brand for mobile mechanics, independent garage owners, and serious DIYers across Britain. Our flagship tools deliver 26+ workshop-level resets-including crucial DPF regenerations and injector coding-alongside an innovative AI assistant that helps you troubleshoot complex faults in seconds. Best of all? We guarantee lifetime free updates. Dealership power, driveway price, and zero subscription traps. Welcome to the future of diagnostics.
