Engine ECU Control Module 2249970 BMW E46 – OEM Used & Tested

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.
