Description
OEM part number A6471530779 identifies this genuine used Engine ECU Module for the Mercedes-Benz W211 E-Class — the refined executive saloon and estate built between 2002 and 2009. Sourced from a written-off W211, this ECU has been tested and verified functional prior to sale.
Designed for a 647-series engine variant of the W211, this ECU controls common-rail diesel injection sequencing, coordinates EGR and swirl flap positions, manages intake air temperature compensation, and communicates with the W211’s COMAND and instrument cluster over the CAN-Bus network.
W211 owners dealing with a failing ECU may face symptoms including sustained limp mode, repeated injection fault codes, rough diesel idle particularly when cold, excessive smoke at start-up, poor throttle response, or unexplained drops in fuel economy on longer runs.
Dispatched in tested working condition. Match OEM number A6471530779 carefully to your vehicle’s engine variant and specification. Professional installation by a Mercedes diesel specialist is advised, and ECU coding or adaptation will be required as standard after fitting. 14-day return policy.
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.
