MECH AI: OBD2 Car Diagnostics

About

One app. Every job. MECH AI is the automotive multitool: AI Mechanic chat, OBD2 code reading, step-by-step repair guides, wiring diagrams, and parts search in one app. Whether you're a DIYer in your driveway or a pro running a shop, get clear answers and step-by-step guidance for your exact vehicle. AI MECHANIC Ask in plain English — or Spanish, Portuguese, Russian, German, French, or Italian. Describe the symptom ("check engine light is on", "grinding noise when I brake") and get the most-likely cause, an estimated repair cost, and a DIY difficulty rating. And when a job needs a lift or special tools, it says so. OBD2 SCANNING Pair a Bluetooth LE or WiFi ELM327 adapter and read stored, pending, and permanent trouble codes — free, with plain-English descriptions from a 9,415-code offline catalog. Live sensor data, emissions readiness, and VIN reading included from DIY up. Read-only: it never clears codes or flashes your ECU. GUIDED DIAGNOSTICS Resumable sessions that walk you through the tests in the order that rules out the cheap causes first, so you don't replace a converter when the problem was an exhaust leak. DIGITAL GARAGE A Vehicle Health score and service timeline per car, built around your year, make, model and mileage. PARTS FINDER Fitment-checked parts from Amazon and eBay, searchable by symptom or part name. TSBs & RECALLS Manufacturer service bulletins and NHTSA recall campaigns by model and year. Confirm VIN applicability and unrepaired status through the official lookup or your dealer. WIRING DIAGRAMS AI-rendered electrical, vacuum, cooling and fuel-system schematics (MECHANIC and up).
