Description
OEM number A0001535379. This is a genuine used and tested Engine ECU Module from a <a href="/brand/mercedes-benz“>Mercedes-Benz W203 C-Class (2000–2007). The unit was extracted from a salvaged vehicle, verified against OEM specifications, and confirmed operational through testing before listing. ¶ The engine management module controls fuel injection pulse width, idle speed stabilisation, and knock detection for the W203’s petrol engine. It reads inputs from the mass airflow sensor, throttle position sensor, and lambda probe to compute the ideal fuel-air ratio, ensuring clean combustion and responsive acceleration. ¶ Signs of failure typically include rough idling, poor cold-start performance, engine hesitation under load, and an illuminated MIL warning. The vehicle may enter limp-home mode to prevent damage, restricting engine output. Fault codes stored in the ECU memory often relate to fuel system richness or leanness out of range. ¶ Tested and confirmed functional, this unit was sourced from a written-off Mercedes-Benz W203. Please match OEM number A0001535379 to your specific vehicle before ordering. Fitting by a trained specialist is advisable, as ECU coding and throttle body adaptation to the host vehicle are typically required.
