Description
OEM number 1429861. A genuine BMW engine ECU control module for the E39 5 Series, removed from a written-off donor vehicle. Carrying the original part number, this unit has been tested prior to listing and is supplied used in verified working order.
The engine control module in the E39 manages all primary engine parameters, including multi-point fuel injection, variable ignition timing, and exhaust gas recirculation. It receives continuous data from engine sensors and adjusts outputs to balance performance with fuel efficiency and emissions compliance, ensuring consistent drivability across all operating temperatures and loads.
E39 owners experiencing ECU issues may notice a no-start condition despite a functional ignition system, or the engine may start but stall shortly afterwards. Dashboard warning lights including the check engine lamp may illuminate persistently. Loss of power, erratic idling, and abnormal fuel consumption are further indicators of electronic control module degradation.
This is a used and tested unit sold as described. Verify OEM number 1429861 against your E39 existing ECU before ordering. Installation should be carried out by a qualified BMW technician, and coding or adaptation of the module to your vehicle is likely to be required. A 14-day return policy 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.
