OBD Diag & Scan is a fully French OBD automotive diagnostic software that offers real-time monitoring of engine parameters and frozen data. It is compatible with any vehicle that supports the OBD or E-OBD standard and requires the use of a BLUETOOTH diagnostic interface, either the ELMbit (old generation) or 16-bit (new generation), or the MPM-COM Bluetooth interface.

The software includes a database of over 3,500 fault codes, regularly updated, with their descriptions in French and, in most cases, repair advice. The "Sensor data" mode enables real-time monitoring of engine parameters in the form of a curve or a dashboard (gauge type). Data logging is possible for later analysis (to help detect failed sensors). The "frozen data" mode allows recording of the engine parameters' state when the fault appeared (a sort of "photo" of the conditions in which the fault was detected).

Updates are free, and the software is an excellent tool for automotive diagnostics.
