Description
OEM number A6111532379. This genuine used and tested Engine ECU Module was sourced from a <a href="/brand/mercedes-benz“>Mercedes-Benz W203 C-Class CDI (2000–2007). Removed from a written-off donor vehicle and tested against original factory specifications to confirm operational integrity before dispatch. ¶ The engine management unit for the W203 CDI controls high-pressure common-rail fuel delivery, injection timing, and smoke limitation under high load. It receives real-time feedback from the fuel pressure regulator and needle lift sensors to fine-tune injection events, maintaining diesel combustion quality while adhering to emission control targets across the engine’s operating map. ¶ Signs of ECU failure include engine hesitation at low revs, excessive diesel smoke, intermittent cutting out at motorway speeds, or the vehicle entering a restricted-power limp mode. Diagnostic scans frequently reveal fault codes for injector leakage, fuel metering valve deviation, or mass airflow plausibility errors when the ECU is at fault. ¶ This original OEM unit was taken from a salvage Mercedes-Benz W203 CDI and confirmed working through functional testing. Ensure OEM number A6111532379 is the correct reference for your engine variant before buying. Professional installation and full ECU coding with injector adaptations are required after fitting.
