A genuine BMW Engine Valvetronic Wiring Harness, OEM part number 8654418, sourced from a donor vehicle. This right-side harness connects the valvetronic motor to the engine control module, managing variable valve lift on 4.4L N63/S63 V8 engines. When this wiring fails, symptoms include reduced power, rough idle, or a check-engine light related to valvetronic faults.
