AutoDiag
OBD-II error codes and engine codes for mechanics
AutoDiag is a practical offline tool for mechanics. It includes the most common OBD-II error codes with causes, symptoms and diagnostic steps, plus engine codes from the vehicle registration document (P.5 field). For each engine code it shows the main car models and recommended timing tools with purchase links. It also has a local AI assistant to help interpret codes quickly. No subscription required.
Hi everyone,
I built AutoDiag because mechanics often need a quick offline reference for OBD-II codes and engine codes from the vehicle registration document.
Instead of jumping between different websites or paid databases, AutoDiag gives you:
- Common error codes with causes and diagnostic steps
- Engine codes (P.5) linked to car models
- Recommended timing tools with purchase links
- A local AI assistant to help interpret codes
It’s a simple, one-time purchase tool that works offline.
Would love your feedback!
