Description
Part number S115300202 A is a Sagem/Siemens engine control module fitted as original equipment across the renault/”>Renault Megane and Scenic model lines. The shared electronic architecture of these two vehicles means a single ECU part number covers both the compact hatchback and the compact MPV across certain engine variants, providing broad coverage within the Renault range.
This module controls the full engine management cycle, including fuel injection pulse width, ignition timing maps, idle regulation, exhaust emissions compliance, sensor diagnostics and the onboard fault-code memory. Precise coordination of these functions is what separates a well-mapped OEM unit from generic replacements.
Symptoms of a failing unit on either model include an engine warning light, stored fault codes across injection, ignition or sensor circuits, rough cold starts, power loss or stalling during normal driving, or a no-start condition unrelated to the immobiliser. An OEM replacement coded to the correct engine variant resolves ECU-sourced faults reliably.
This module has been removed from a Renault vehicle, tested under load and confirmed functional. It is supplied as a genuine used part with part number S115300202 A 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.
