Description
Genuine used Mercedes-Benz engine control unit with OEM number A6281531879, suitable for selected Mercedes-Benz W220 S400 CDI vehicles equipped with the 4.0 CDI V8 diesel engine. This original factory ECU manages critical engine functions including fuel injection, turbocharger control, sensor processing, engine protection and communication with other vehicle control systems.
The module receives and processes data from multiple engine sensors to regulate injection timing, fuel quantity, boost pressure and other operating parameters required for correct V8 CDI performance. Mercedes-Benz used several ECU versions across different production years and specifications, so visually similar modules may contain different hardware, software or coding configurations.
This is a genuine used Mercedes-Benz electronic component and may show normal cosmetic signs from previous installation, removal, handling or storage. Light scratches, marks or surface wear are typical for original second-hand automotive electronics.
Before ordering, compare OEM number A6281531879 directly with the number on your existing ECU. Also verify the connector layout, hardware/software references, engine specification and vehicle configuration. Programming, coding, adaptation or immobilizer synchronization may be required after installation. Professional diagnosis and installation are strongly recommended.
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.
