A0245453332 Mercedes-Benz W220 Modulo ECU Motore – Originale Usato e Testato

Descrizione

Lo A0245453332 è un'unità di gestione motore originale di fabbrica progettata per il Mercedes-Benz W220 S-Class — la berlina di lusso ammiraglia prodotta dal 1998 al 2005. La W220 rappresentava l'apice del Mercedes-Benz engineering at the time of its production, and this ECU reflects that standard, managing a complex array of engine functions across the S-Class powertrain with the precision demanded of the flagship model.

This module communicates with the W220’s extensive sensor network and integrates with the vehicle’s CAN bus to share data with the transmission controller, suspension management system and climate control unit. It governs fuel injection timing, lambda regulation, idle speed control and emissions functions, enabling the S-Class engine to meet its design targets for refinement, power output and long-term durability.

Signs that the ECU on a W220 S-Class may need attention include the engine starting normally but stalling after a few seconds, intermittent power loss at motorway speeds, multiple fault codes appearing simultaneously without an obvious common cause, or the vehicle entering protection mode despite normal sensor readings throughout the diagnostic scan.

This part is a genuine used OEM unit removed from a W220 S-Class and bench-tested before despatch. All second-hand engine control modules — particularly those from higher-specification vehicles such as the W220 — may require professional coding and adaptation to the target car. Match the OEM number to your existing unit before ordering.
