Deep OBD is an open source Android application for OBD communication developed by Ulrich Holeschak. The app uses ECU files for OBD communication and theoretically supports all operations that are possible with ISTA-D, INPA or Tool32. However, currently only vehicles from BMW and VAG are supported.

The app offers a configuration generator that allows users to select the diagnostics jobs to execute and create their own configuration files. For complex tasks, the configurations files can be created manually. The application requires 2.5 GB of free external storage and supports various OBD II adapters including Standard FTDI based USB "INPA compatible" D-CAN/K-Line adapters (all protocols), ELM327 based Bluetooth and WiFi adapters, Custom Bluetooth D-CAN/K-Line adapter (BMW-FAST protocol over D-CAN and K-Line), a replacement firmware for the ELM327 Bluetooth adapter that is faster, more stable and also supports K-Line (required for VAG vehicles, supports protocols KWP2000, KWP1281, TP2.0), and Deep OBD ENET WIFI adapter (for BMW F-models).

Overall, Deep OBD is a useful app for BMW and VAG vehicle owners who want to perform OBD communication with their cars.
