Description
Identified by OEM number 1430940, this engine ECU control module is a genuine used, tested unit for the BMW E46 compact saloon and coupe range. With the E46 continuing to attract enthusiast ownership decades after production ended, quality used components such as this are in growing demand. The module was extracted from a written-off donor and checked against factory data.\n\nThe ECU at OEM number 1430940 performs continuous real-time analysis of engine operating conditions, adjusting injector open time, ignition dwell, and idle speed control valve position to maintain stable combustion. It also handles fuel evaporative emissions purge control and communicates fault status via the OBD-II diagnostic port.\n\nA degraded ECU on the E46 can produce a pattern of intermittent faults that are difficult to pin down: random misfires that clear themselves, rough idle that appears only in certain ambient temperatures, a tendency to surge at light throttle on the motorway, and recurring fault codes that return shortly after being erased with a diagnostic reader.\n\nThis is a used and tested genuine ECU sold under OEM number 1430940. It is the buyer’s responsibility to confirm this reference against their specific E46 engine code and production date before ordering. Professional installation is required, and the module will need coding and adaptation to operate correctly in the receiving vehicle. A 14-day return window is in place.
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.
