Description
Used original Marelli engine control unit ECU for Fiat and Lancia Dedra applications, with primary OEM number WH4T.07 and alternate reference IAW 04T. This electronic control module is designed for the engine management system and is suitable for the models named above.
At the heart of the injection and ignition system, the ECU processes signals from the engine sensors and controls key operating functions such as fuel delivery, ignition timing, idle behavior, and overall running balance. A correct working unit is essential for stable starting, smooth performance, and consistent engine response.
Common signs of a faulty unit include no-start conditions, intermittent starting, uneven idle, misfiring, hesitation under load, poor throttle response, or warning faults linked to engine management. In some cases, communication problems during diagnostics or erratic fueling behavior can also point to ECU failure.
This is a used original part, removed from a vehicle and tested before sale. Please match WH4T.07 and IAW 04T exactly before ordering. Professional installation is recommended, and coding, programming, or adaptation may be required depending on the vehicle setup.
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.
