Description
This engine control module is identified by two OEM references — S111730108 c and HOM7700864451 — and was fitted as original equipment on the renault/”>Renault Megane. The suffix variant ‘c’ distinguishes this unit within the S111730108 series, and cross-referencing with HOM7700864451 provides a reliable means of confirming correct application against vehicle build records.
The ECU manages injection quantity, ignition timing, idle speed control, turbocharger boost on applicable variants, lambda correction loops and the full suite of OBD diagnostic monitoring. Each parameter is mapped to the specific engine during initial calibration, ensuring the powertrain operates within its designed efficiency and emissions envelope.
On the Megane, common signs of ECU failure include an engine management warning light, fault codes in injection or sensor circuits, rough or unstable idle, poor throttle response, loss of power or a no-start condition. Fitting a tested OEM replacement removes the ECU as a variable and returns the engine to factory operation.
Sourced from a Renault Megane in running condition, this module has been tested and verified. It is supplied as a genuine used part with both OEM numbers — S111730108 c and HOM7700864451 — confirmed.
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.
