Description
OEM reference 7794624 identifies this Engine ECU Control Module, produced for BMW‘s E46 3 Series platform. Recovered from a written-off donor vehicle and put through a full functionality test, this is an authentic replacement sourced and verified to original manufacturer standards.
The ECM in the E46 3 Series coordinates ignition timing, fuel delivery, idle speed control, and knock sensor response to keep combustion efficient across all operating temperatures. It interprets signals from the camshaft sensor, coolant temperature sensor, and lambda probes to ensure clean, responsive engine behaviour at every rev range.
Common signs of ECM failure include erratic idle quality, hard starting particularly from cold, recurring fault codes, and misfires on one or more cylinders. In more advanced cases the engine management light illuminates continuously, power output drops noticeably, or the drivetrain enters a restricted limp-home state.
This unit ships as a used, tested part — verify that OEM number 7794624 corresponds to your exact build before purchase. Fitting by a qualified technician is recommended, and post-installation coding or DME adaptation may be necessary. Returns accepted within 14 days of receipt.
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.
