moDiag is a Windows-based automotive diagnostic software developed by Matthias Tieben. Built for both enthusiasts and professionals, it works with common OBD interfaces (including ELM327, KKL/ISO, and CAN-capable adapters) to communicate with standard OBD-II/EOBD systems and, where supported, manufacturer-specific control units. With moDiag, you can read and clear diagnostic trouble codes, view freeze-frame data, monitor live sensor values, and record and graph data for deeper analysis. It also offers practical service functions—such as resetting service indicators on supported vehicles—and provides advanced capabilities like actuator tests, adaptation routines, and customizable PIDs, depending on the ECU and adapter used.
The software emphasizes reliability and clarity, featuring a clean interface, multilingual support, session logging, and export options for CSV and printable reports. Whether you’re diagnosing a check engine light or tracking performance trends, moDiag delivers stable communication, informative visualizations, and efficient workflows at an accessible price point. Vehicle and feature compatibility depend on the specific interface and control units in use; consult the documentation to confirm coverage for your setup.
