Beschreibung
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.
Rücksendungen werden nur bei tatsächlichen Mängeln akzeptiert – defekt bei Erhalt, nicht wie beschrieben oder falsches Teil geliefert – und müssen innerhalb von 14 Tagen beantragt werden, wobei alle 3 Manipulationsschutz-Aufkleber intakt sein müssen. Keine Rücksendungen aufgrund von Meinungsänderungen, fehlerhafter Installation, Codierung/Programmierung oder Kompatibilitätsfehlern seitens des Käufers; die Überprüfung der Kompatibilität (OEM-Nummer, Firmware, Fahrzeug) liegt in der Verantwortung des Käufers.
