Description
OEM number 0261200387 identifies the engine ECU (engine control module) for the BMW E30 and E34. This is a genuine used Bosch Motronic unit removed from a running vehicle and professionally tested before listing.
The engine ECU governs all engine management parameters: fuel injection timing, air–fuel mixture, ignition timing, throttle response and communication with sensors throughout the engine bay. A correctly matched control unit preserves factory engine behaviour, efficiency and performance without the compromises of aftermarket alternatives.
Symptoms of a failing ECU include engine entering limp mode, persistent misfires, unexplained loss of power, rough idle, a persistent engine warning light, or a no-start condition where all other components test correctly. Diagnostic scans pinpointing the ECU directly rather than sensors or wiring make this a cost-effective repair path.
Connectors are intact and the housing shows no visible damage. Verify OEM number 0261200387 against the label on your existing ECU before ordering — an exact match is mandatory. Professional installation is required; immobilizer synchronisation and ECU coding will be needed depending on your vehicle’s configuration. Covered by our 14-day returns policy for genuine faults.
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.
