Description
Catalogued under OEM number 0261203276, this Engine ECU Control Module is a genuine Bosch-manufactured unit fitted by BMW to the E36 3 Series — a classic platform with a loyal following worldwide. Pulled from a written-off donor and functionally verified, this used ECM is a proven choice for restoring your E36 engine management system.
The E36 3 Series ECM handles Bosch Motronic fuel injection and ignition management: it interprets signals from the airflow meter, coolant and intake temperature sensors, and the oxygen sensor to calculate injector pulse width and ignition timing advance. Smooth engine warm-up, idle stability, and long-term fuel trim adaptation all depend on this Motronic unit functioning within specification.
A failing ECM in the E36 often results in rough idle, black smoke from over-fuelling, misfires at idle or under load, and difficulty restarting after a hot soak. Fault codes relating to fuel mixture, sensor signal range, or ignition circuit faults are typical, and in some cases the engine may refuse to start at all.
Sold used and tested — match OEM number 0261203276 to your E36 engine code before ordering. Professional installation is recommended, and coding or ECU adaptation procedures may be required following fitment. A 14-day return period is offered on this item.
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.
