Description
Engine ECU Control Module for BMW E46, OEM part number 1430940. Removed from a running vehicle and fully tested before listing. This unit manages core engine functions including fuel injection, ignition timing, air-fuel mixture and throttle response, ensuring stable performance and efficient engine operation.
A faulty or failing ECU can cause a range of drivability issues such as no-start conditions, misfires, loss of power, limp mode activation or persistent engine warning lights. Replacing with a tested OEM unit helps restore correct communication between the engine management system, sensors, injectors, ignition coils and immobilizer for reliable everyday operation.
This module is in good used condition with no corrosion or damaged connectors. OEM part number 1430940 is specified for exact fitment. Always verify this number against your vehicle before purchase to confirm compatibility. Designed as a direct replacement where part numbers match exactly.
Professional installation is recommended. Depending on your vehicle configuration, coding, programming or immobilizer synchronization may be required after fitting. Diagnostic equipment may be needed for proper adaptation and fault code clearing.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
