Description
OEM number A6111537779. A genuine used and tested Engine ECU Module from a mercedes-benz“>Mercedes-Benz W203 C-Class CDI (2000–2007). Removed from a salvaged vehicle and subjected to functional testing to confirm it meets the original equipment manufacturer’s operational standards. ¶ This CDI diesel engine management unit regulates fuel injection quantity, injection timing advance, and pilot injection strategy for the W203 C-Class diesel engine. It monitors rail pressure feedback and coolant temperature to adapt fuelling across all load points, and manages the exhaust gas recirculation system to balance power output against emissions compliance. ¶ A degrading ECU on a CDI-engined C-Class may cause excessive smoke, rough running at idle, difficulty starting when hot or cold, or a sudden loss of engine power accompanied by a flashing glow-plug warning. Fault codes relating to injector balance rates, rail pressure deviation, or EGR valve control are commonly associated with ECU malfunction. ¶ Sourced from a salvage Mercedes-Benz W203 CDI and tested to confirm full functionality before sale. Please confirm OEM part number A6111537779 is appropriate for your vehicle before ordering. Professional installation is necessary, and injector coding plus ECU adaptation are required after fitting. A 14-day return period is in place.
