The BMW ECU / ECM / DME Engine Control Module (OEM 8661706) is a used genuine unit removed from a donor vehicle. This module, also known as the engine control unit or DME, manages ignition, fuel delivery, and emissions on the 0.6L range-extender engine, or serves as the primary vehicle controller on battery-electric models. It replaces several earlier numbers including 8642338, 8642242, 8635447, 8631718, and 7504988. Programming/coding to your specific vehicle is required upon installation—have this done by a qualified shop or dealer to ensure proper integration with the i3 or i3s.
