Description
The Mercedes-Benz W211 E-Class, produced from 2002 to 2009 in saloon and estate forms, uses this genuine Engine ECU Module, OEM number A6471500079. Extracted from a written-off vehicle and confirmed fully operational through functional testing, this unit is ready for professional installation.
This ECU, designed for a 647-series diesel engine, orchestrates the precise injection timing and duration of the common-rail system, manages turbocharger boost pressure, processes glow plug control for cold starts, and oversees exhaust aftertreatment coordination to maintain emissions compliance.
Typical ECU-related faults on the W211 diesel include persistent hard starting in cold weather, heavy black or white smoke at idle, severe loss of engine performance, recurring fault codes for the rail pressure regulator or injector circuits, and the vehicle locking into engine limp mode.
Confirmed working through testing and dispatched in functional condition. Before ordering, carefully verify that OEM number A6471500079 matches your engine variant. Installation must be performed by a qualified specialist, and ECU coding or programming adaptation is required for proper integration. 14-day returns apply.
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.
