Description
Part number S122326107 A is the original-equipment engine control module for the renault/”>Renault Mégane II — the second generation of Renault’s popular compact hatchback and saloon range. Taken from a fully operational vehicle and put through functional testing before listing, it represents a solid used alternative to a new dealer-supplied unit at a considerable saving.
This ECU manages the full scope of the Mégane II engine management cycle, encompassing fuel delivery mapping, ignition timing or injection event sequencing depending on engine variant, idle speed regulation, closed-loop lambda correction, and the emission control strategies required for the vehicle’s certified limits. Sensor inputs from the air mass meter, throttle position sensor, coolant temperature sensor, and crankshaft position sensor feed the module continuously to maintain accurate combustion control.
Symptoms commonly associated with a failing ECU in the Mégane II include a persistent engine warning light, erratic or surging idle, hesitation during acceleration, and difficulty starting — particularly after the engine has reached operating temperature. Diagnostic equipment typically produces control module fault codes after sensors and wiring connectors have been ruled out as the primary cause.
Verify part number S122326107 A against the label on your current ECU before ordering. As with all VIN-coded engine management modules, this unit will require coding or cloning by a suitably equipped specialist to the receiving vehicle’s immobiliser and engine calibration data before it can be placed into service.
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.
