CarDiag : Car Diagnostic OBD2

CarDiag : Car Diagnostic OBD2 is your personal automotive diagnostic tool, putting professional-grade car diagnostics in your pocket without the mechanic's bill. Pair it with any affordable Bluetooth OBD2 device and take control of your vehicle's health.

Stop guessing about engine problems. With automatic OBD2 diagnostics, CarDiag reads your car's fault codes and translates them into plain language anyone can understand. Whether it's a worn component, battery issue, or emission system malfunction, you'll know exactly what's wrong before stepping foot in a garage. No more paying €50 just for a diagnostic scan — identify problems yourself, instantly.

Beyond diagnosis, CarDiag guides you through the entire repair journey. Get step-by-step DIY repair tutorials for common fixes, discover cost-effective ways to source parts, and receive honest repair estimates from mechanics near you. The manual diagnostic mode lets you describe symptoms (strange noises, warning lights, unusual smells) and receive expert guidance on what to check. You're never alone in troubleshooting your vehicle.

Reset that frustrating check engine light in seconds. The malfunction indicator lamp (MIL) often triggers for minor issues that don't require immediate repair — CarDiag lets you clear it after diagnosis, eliminating unnecessary anxiety. The digital maintenance book keeps your entire service history organized: store invoices, track repairs performed by you or professionals, and maintain a complete record for resale value and warranty purposes.

Routine maintenance checks become effortless. Perform pre-purchase vehicle inspections, schedule regular check-ups, or verify your car's condition before long trips. CarDiag supports all OBD2-compatible vehicles: US models from 1996 onward, European cars from 2001 (diesel from 2003), and Japanese vehicles from 2006 — covering the vast majority of cars on the road.

All you need is a budget Bluetooth OBD2 scanner (available for under $10 online) and your smartphone. Installation takes seconds; diagnostics take minutes. CarDiag : Car Diagnostic OBD2 transforms expensive garage visits into informed decisions you make yourself, saving thousands over your vehicle's lifetime.
