BMW DDE5 Pinout. Schematic Diagram
BMW DDE5 is a pinout and wiring diagram for the BMW DDE5 series diesel engine control unit. This page provides information on the diagrams for various models:
DDE506 E65/M57TU
DDE506 E46/M57TU
DDE508 E60/M57TU
These diagrams help determine the pin assignments of the control unit connector (CAN bus, power supply, ignition, sensors, injection control, and other signals). This information will be useful for diagnostics, repairs, chip tuning, and equipment connection when working on BMWs.
