Description
Carrying the Sagem/Siemens part number S105300104 C, this engine control module was fitted as original equipment on the renault/”>Renault Megane. The Megane is Renault’s enduring compact model, sold in hatchback, saloon, coupé and estate variants with a broad selection of petrol and diesel engines, each requiring precise ECU calibration to the installed powertrain.
This module governs fuel injection, ignition timing, boost pressure management on turbocharged variants, idle speed regulation and the suite of emissions-related functions demanded by European type approval. It processes data from crankshaft position, camshaft, coolant temperature, mass airflow and oxygen sensors to deliver the correct fuelling at all times.
Owners typically encounter a failing ECU through stored fault codes in injection or sensor groups, an engine management warning light, erratic idle, power loss under load or a failure to start. Replacement with a correctly coded OEM unit returns the engine to its mapped operating parameters.
This unit has been removed from a Renault Megane, tested and verified functional. It is supplied as a genuine OEM used part with part number S105300104 C 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.
