Diagnostics by car make

Every make below can be diagnosed with Diagnost: OBD-II fault reading with a cheap ELM327 adapter right in your browser, an AI mechanic that knows each model's weak points, and a free program for Windows and macOS that scans every module.

Don't see your car?

The AI diagnoses any make and model — describe the symptoms or paste your fault codes. Every car sold since 2001 (petrol, EU; 1996 US) or 2004 (diesel) has OBD-II.
