Description
Carrying OEM number 1743247, this Engine ECU Control Module represents a genuine BMW part for the E36 3 Series, closely related to but distinct from adjacent E36 ECM variants. Drawn from a written-off donor vehicle and subjected to individual diagnostic testing, this used unit is prepared as a genuine, tested replacement.
The E36 ECM governs the Motronic injection and ignition strategy, managing fuel delivery across idle, part-load, and wide-open throttle conditions by referencing the load signal from the airflow meter and the rpm signal from the crankshaft encoder. Secondary functions include evaporative emissions purge control, idle air bypass management, and adaptation of fuel trim against long-term lambda feedback.
When this module begins to degrade in the E36, symptoms can include hard starting after hot soak, a rough idle that improves once the engine reaches operating temperature, hesitation during acceleration from low revs, and a persistent engine management light with codes relating to fuel mixture adaptation or ignition timing deviation.
This unit is offered used and tested — cross-reference OEM number 1743247 with your E36 engine code and variant before ordering to confirm fitment. Installation by a technician experienced in classic BMW engine management is recommended, and coding or adaptation procedures may be required after fitting. A 14-day return policy is available.
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.
