Engine ECU Control Module 7500255 BMW E39 E38 E46 – OEM Used & Tested

Opis

OEM number 7500255 covers this genuine used, tested engine ECU control module across the BMW E39, E38, and E46 platforms — a broad fitment range spanning the 3 Series, 5 Series, and 7 Series production runs of the late 1990s and early 2000s. The unit has been removed from a written-off vehicle and validated against the original manufacturer data.\n\nThis ECU manages engine speed governing, sequential port fuel injection, and ignition map selection across multiple driving modes. By reading throttle pedal position, ambient air pressure, and exhaust gas composition simultaneously, it calculates optimum combustion parameters to balance driver demand with fuel economy and emissions performance.\n\nCommon failure symptoms shared across the E39, E38, and E46 include erratic idle speed that oscillates without driver input, misfires that appear only at operating temperature, a loss of power most pronounced at higher engine speeds, and an engine management light paired with diagnostic codes pointing to the ECU output stage or fuel trim limits.\n\nListed as a used and tested genuine ECU, this module carries OEM number 7500255. Confirm compatibility with your specific model, engine code, and build date across the E39, E38, or E46 range before ordering. Professional installation is required, and coding or adaptation to the receiving vehicle will be necessary post-fitting. A 14-day return policy applies.
