Description
Part number S100811102 e identifies this Sagem/Siemens engine control module as original equipment for the renault/”>Renault Laguna. The Laguna served as Renault’s executive model across its production generations, offering refined petrol and diesel powertrains in hatchback, saloon and estate body styles, each dependent on correctly calibrated ECU hardware for optimal performance.
This module controls injection timing and fuel quantity, ignition advance mapping, idle speed regulation, exhaust gas recirculation, lambda sensor feedback and the full onboard diagnostic system. Accurate management of these parameters defines fuel economy, power output and compliance with emissions legislation.
On the Laguna, a deteriorating engine ECU typically surfaces as an engine warning light, stored fault codes across injection or sensor channels, hesitant or rough idle, reduced responsiveness under acceleration, or an intermittent no-start unrelated to other systems. Replacing with a correctly matched OEM unit resolves ECU-sourced faults definitively.
This unit was removed from a Renault Laguna and tested to confirm correct function. It is supplied as a genuine used part with part number S100811102 e 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.
