Get a professional AI diagnostic report for your vehicle in under 5 minutes. Here's exactly how it works.
You need an OBD-II scanner to read the fault code from your car. Basic scanners cost from £8 on Amazon and plug into the 16-pin OBD port under your dashboard. Bluetooth scanners work with a free smartphone app. You only need to read the code — you do not need to clear it.
With the ignition on (engine off for most scanners), plug the scanner into your OBD-II port. The scanner will display any stored fault codes — for example P0420, P0171, or P0300. Note down the exact code.
On AI-Diagnostics-Pro, enter your vehicle's year, make, model and engine size, plus the fault code you read. The more accurate your vehicle details, the more specific your report will be.
Pay £1.59 securely via Stripe — a one-time payment, no subscription. Your AI-generated report is delivered instantly. It includes a plain-English explanation of the fault, the most likely causes specific to your vehicle, UK repair cost estimates (parts and labour), MOT implications, and a step-by-step fix guide with DIY difficulty rating.
Take the report to your mechanic to save time and avoid being overcharged. Or use the DIY guide to fix it yourself if it's within your ability. The report also tells you whether it is safe to drive and whether the fault is likely to cause an MOT failure.
Every report is vehicle-specific — generated using your exact year, make, model, engine size, and fault code. It is not a generic description that applies to every car equally.
You do not need an expensive scanner. Any OBD-II scanner that reads fault codes will work. The key difference is how many systems they cover.
Budget wired (from ~£25)
Engine codes only. No phone needed.
Bluetooth dongle (from ~£35)

The report is generated for the code you enter. If you enter the wrong code, the report will still be accurate for that code — but it may not match your actual problem. Double-check the code on your scanner before submitting.
Your report is available for 12 hours after purchase. You can reopen it as many times as you like during that window using the link provided after payment.
Yes, as long as your car supports OBD-II diagnostics. In the UK, that covers petrol cars from 2001, diesel cars from 2004, and many later-1990s vehicles.
