Diag Drive: AI Car Mechanic

Check-engine light on? Find out why in seconds. Describe the problem, snap a photo or record the noise and get a step-by-step fix for your exact car.

Stop guessing. Stop overpaying. Diag Drive is the AI master mechanic in your pocket: tell it what your car is doing and get a clear, step-by-step fix written for your exact make, model and engine.

DESCRIBE IT, SNAP IT OR RECORD IT • Type the symptom in plain English: "rough idle when cold", "clunk over bumps", "squeal when braking". • Photo inspection: point your camera at a leak, a worn part or a dashboard warning light. • Noise diagnosis: record up to 15 seconds of a knock, tick, whine or rattle and let the AI listen.

ANSWERS THAT FIT YOUR CAR • Knows your vehicle, the tools in your toolbox and what's already been replaced. • Gives the most likely cause first, then the next suspects, then the checks to confirm it. • Flags anything safety-critical: brakes, steering, airbags, fuel leaks and EV high voltage.

OBD-II SCANNER (BETA) Plug in a Bluetooth LE or Wi-Fi ELM327 adapter (OBDLink, Vgate vLinker, Veepeak and more) and: • Read and clear engine fault codes: stored, pending and permanent. • See the freeze-frame data saved the moment the fault happened. • Watch live data: RPM, speed, coolant temperature, load, boost, fuel trims and battery voltage. • Check readiness monitors before your MOT or inspection. • Record a drive and let the AI analyse the log. • Ask the AI to explain all your codes together. Works on most petrol cars from 2001 and diesels from 2004. No adapter yet? Try the built-in demo.
