Description
This is a used original Bendix engine control unit ECU for Renault 19 and Renault 21 1.7 models, with primary OEM number S101263101B. Built as the vehicle’s engine management computer, it is designed for the Renault applications named above and suits owners seeking the correct original electronic control unit.
The ECU manages core engine functions by processing input from key sensors and controlling ignition and fuel-related operation to keep the engine starting, idling and running correctly. It plays a central role in overall drivability, helping the engine respond properly under load, during warm-up and across normal road use.
Common signs of a faulty unit include non-starting, intermittent starting problems, uneven idle, hesitation, misfiring, poor throttle response or engine cut-out. In some cases, an internal ECU fault can also lead to inconsistent running, loss of performance or communication issues during diagnosis.
This is a used original part removed from a vehicle and tested before sale. Please match the exact OEM number S101263101B before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle configuration and workshop 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.
