Descripción
This Engine ECU Control Module, referenced under OEM number 7791190, was engineered by BMW for the E46 3 Series. Extracted from a written-off vehicle and passed through diagnostic testing, it offers a genuine, used alternative to costly new or remanufactured units.
Managing the engine in the E46 3 Series demands precise multi-point coordination: the ECM balances fuel injector timing, ignition dwell, variable valve timing signals, and idle actuator output simultaneously. It continuously cross-references coolant temperature, intake air temperature, and throttle position to maintain optimal power delivery and emissions compliance.
When this module begins to fail, symptoms often include rough or hunting idle, intermittent misfires, loss of power during acceleration, and difficulty holding a steady cruising speed. Fault codes related to fuel trim, sensor signals, or ignition circuits frequently accompany these driveability issues.
Offered as a used, tested component — always verify OEM number 7791190 against your vehicle’s build data before ordering. We recommend installation by an experienced technician, as coding or adaptation procedures may be required after the module is fitted. A 14-day return policy covers this item.
Solo se aceptan devoluciones por defectos reales —producto defectuoso a la recepción, que no se ajuste a la descripción o que se haya suministrado una pieza incorrecta— solicitadas en un plazo de 14 días, siempre que las tres pegatinas de seguridad estén intactas. No se admiten devoluciones por cambio de opinión, instalación incorrecta, codificación o programación, ni por errores de compatibilidad por parte del comprador; es responsabilidad del comprador comprobar la compatibilidad (número OEM, firmware, vehículo).
