D-PDU API is a standard automotive diagnostic API library developed by **Softing**, It serves as the low-level driver interface for original equipment manufacturer (OEM) diagnostic software from VAG (Volkswagen, Audi), Mercedes-Benz, BMW, and others, facilitating communication between a PC and the vehicle’s ECU, and supports CAN/LIN/K-line diagnostic hardware (such as CANoe, ODIS, and VAS devices).

D-PDU API = Diagnostic Protocol Data Unit API, which is the underlying communication middleware for automotive diagnostics. Each version represents an iterative update, and “x64only” indicates support for 64-bit Windows only.
