Descripción
Catalogued under OEM number 7803372, this Engine ECU Control Module was designed by BMW to serve both the E87 1 Series and the E90 3 Series. Drawn from a written-off vehicle and subjected to thorough testing, this is a genuine used part that meets original factory performance criteria.
Shared across the E87 and E90 platforms, this ECM regulates fuel injection sequencing, ignition coil dwell time, throttle actuator position, and emissions control systems including EGR and catalytic converter monitoring. Its adaptive learning capability allows it to fine-tune fuel trim and idle correction based on accumulated driving data from oxygen and mass airflow sensors.
A failing ECM on either the E87 1 Series or E90 3 Series typically produces symptoms such as misfires, rough idle, power loss, and difficulty starting. Owners may notice the engine management warning light illuminating, accompanied by fault codes pointing to sensor circuit faults or fuel system irregularities.
Supplied as a used, tested component — cross-check OEM number 7803372 with your vehicle identification data before buying. Specialist installation is recommended, and coding or programming adaptation to your car’s DME network may be required. A 14-day return period applies to 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).
