BMW Engine Wiring Harness (module 1) with OEM part number 8605454, also superseding 7619134. This is a used genuine BMW part, removed from a donor vehicle. It serves as the primary electrical harness connecting sensors and actuators to the engine control system. A common failure symptom is intermittent stalling or a no-start condition due to chafed or corroded wires within the harness. This harness is specific to the N20 and B48 2.0L turbocharged four-cylinder engines found in the 320i, 328i, X1, and Z4.
