Description
This Siemens engine control unit ECU is an original Renault electronic module for Renault Espace II 2.0 models. The primary OEM number is 7700859558, with alternate reference 7700869314. Built as a genuine factory control unit, it is the central computer that manages core engine functions and supports correct running, response and overall drivability.
Working continuously with sensor inputs, the ECU calculates and adjusts fuel delivery, ignition timing and other engine management commands. It helps the engine start properly, idle steadily and perform efficiently across different driving conditions while coordinating key electronic control processes within the petrol engine system.
Common signs of a faulty unit include non-starting, intermittent starting problems, rough idle, misfiring, hesitation, poor throttle response or irregular engine behavior. In some cases, warning lights, injector control issues or loss of communication during diagnostics can also point to an ECU fault.
This is a used original part, removed from a vehicle and tested before sale. Please match 7700859558 and 7700869314 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on the vehicle setup and replacement procedure.
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.
