Description
Part number 2249970 is the OEM reference for this genuine used, tested engine ECU control module for the BMW E46. Drawing from a comprehensive E46 production run that included some of the finest inline-six engines produced by BMW, this unit was sourced from a written-off example and cross-referenced against original manufacturer data before being listed for sale.\n\nThis ECU controls the digital motor electronics strategy for its designated engine variant, integrating inputs from the hot-film air mass meter, crankshaft speed sensor, and individual cylinder knock sensors to deliver cylinder-selective ignition timing and accurate fuel injection quantity. It also manages the idle speed actuator for stable warm-up operation.\n\nWhen this ECU develops a fault, drivers may experience difficulty getting the engine to idle smoothly after a cold start, sudden misfires that set individual cylinder codes, a reduction in power accompanied by increased fuel consumption, or a vehicle that intermittently enters emergency running mode with throttle response severely curtailed.\n\nSupplied as a genuine used and tested part, this ECU is identified by OEM number 2249970. Verify this against your specific E46 configuration and engine type before purchasing. A qualified BMW technician should carry out installation, and the module will need to be coded or adapted to the recipient vehicle after fitting. Returns accepted within 14 days.
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.
