Description
This engine control module carries two OEM references — S111730108 b and HOM7700864451 — and was supplied as original equipment on the renault/”>Renault Megane. Cross-referencing both numbers ensures accurate fitment identification when searching through dealer catalogues, parts databases or existing vehicle documentation.
The ECU is responsible for the complete engine management cycle: calculating the correct fuel injection quantity and timing, setting ignition advance, managing idle speed, monitoring lambda sensor output and storing fault codes whenever a sensor or actuator operates outside its designed tolerance. Any compromise in these functions directly affects driveability and emissions.
A failing Megane engine ECU typically manifests as stored diagnostic fault codes, an illuminated engine management light, hesitation or stumbling under load, poor cold-start behaviour, or an intermittent no-start. Replacement with a correctly matched OEM unit restores full engine control without recalibration of core injection maps.
This module was sourced from a Renault Megane in operational condition and has been tested and confirmed serviceable. It is supplied as a genuine used part with both part numbers — S111730108 b and HOM7700864451 — verified.
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.
