Descrizione
OEM number 0261200520 marks this engine ECU control module as a genuine used, tested unit spanning the BMW E30 and E36 platforms — two of the most celebrated compact sports cars in BMW’s history. Recovered from a written-off donor vehicle, it has been cross-checked with original Bosch Motronic specification data before listing.\n\nBuilt around the Bosch Motronic architecture, this ECU processes distributor ignition timing signals alongside injector pulse-width data to govern combustion across all engine speeds. Air mass measurement and coolant temperature inputs allow the unit to apply cold-start enrichment, idle speed compensation, and overrun fuel cut-off as conditions demand.\n\nOn the E30 and E36, a deteriorating ECU typically manifests as unsteady cold-start idling, a tendency to stall when engine revs drop below idle speed, intermittent cylinder misfires under hard acceleration, and a check engine warning. Fault codes from the Bosch diagnostic system will often confirm that the ECU is the source of the issue.\n\nThis used and tested ECU is a genuine Bosch Motronic unit bearing OEM number 0261200520. Verify the number against your specific E30 or E36 engine code before ordering. Qualified installation is required, and the unit may need adaptation or coding to your vehicle’s immobiliser and sensor calibration after fitting. A 14-day return period is in place.
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.
