Description
This Engine ECU Control Module, listed under OEM number 1432521, is a genuine BMW part produced for the E36 3 Series. Extracted from a written-off vehicle and individually tested before listing, it offers an authentic replacement for a worn or failed E36 ECM without the expense of a new or remanufactured unit.
Managing the E36’s Motronic system, this ECM controls fuel injection timing, ignition advance, idle speed stabilisation via the auxiliary air valve, and closed-loop lambda control. The module adapts long-term fuel corrections based on accumulated oxygen sensor feedback, keeping the air-fuel ratio within tight bounds for consistent performance and emissions compliance.
When this module begins to fail, E36 owners typically report an erratic or hunting idle, hard cold starts, a rich or lean smell from the exhaust, and misfires that worsen in damp or cold weather. Fault memory entries for oxygen sensor adaptation limits, temperature sensor plausibility, or injector circuit faults commonly accompany these symptoms.
This is a used, tested part — confirm OEM number 1432521 against your E36 engine and build specification before purchasing. We recommend installation by a technician familiar with E36 engine management, and coding or ECU adaptation may be required after fitting. Returns are 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.
