Description
Genuine used Mercedes-Benz engine control unit with OEM number A6481531779, intended for selected Mercedes-Benz W220 S-Class vehicles equipped with the 3.2 CDI diesel engine. This original factory ECU manages key engine operating parameters and coordinates functions such as fuel injection, turbocharger control, sensor processing, engine protection strategies and communication with other electronic modules in the vehicle.
The control unit receives data from multiple engine sensors and uses this information to regulate combustion, injection timing and overall engine performance. Different W220 3.2 CDI versions can use control units that appear very similar externally but contain different software, coding or hardware configurations, so the complete OEM reference must be checked carefully before replacement.
This is a genuine used Mercedes-Benz electronic module and may show normal cosmetic signs from previous installation, removal, transport or storage. Minor scratches, marks or surface wear are typical for original second-hand ECU units.
Before ordering, compare OEM number A6481531779 with the number on your existing control unit. Also verify the electrical connectors, hardware and software references and vehicle configuration. Depending on the installation, coding, programming, adaptation or immobilizer synchronization may be required. Professional diagnosis and installation are recommended before replacing the original ECU.
