Description
OEM number A0255457232. A genuine used and tested Engine ECU Module for the mercedes-benz“>Mercedes-Benz W202 C-Class (1993–2000). This original equipment unit was removed from a written-off salvage vehicle and tested against factory calibration standards to verify that it remains fully operational. ¶ Managing the ignition and injection strategy of the W202 C-Class petrol engine, this module controls injector opening duration, ignition coil charge time, and exhaust gas recirculation scheduling where applicable. It adapts its fuel maps continuously using feedback from the heated oxygen sensors, maintaining the air-fuel ratio within tight stoichiometric limits for both catalyst efficiency and performance. ¶ When this ECU begins to fail on the W202, symptoms can include a lumpy idle that worsens in cold weather, an engine that stalls when coming to a stop in traffic, reduced acceleration, or a persistent check engine lamp. Diagnostic tools may log codes for fuel trim learning blocked, oxygen sensor heater circuit faults, or ignition timing deviation from the expected range. ¶ Removed from a written-off Mercedes-Benz W202 and confirmed working. Check that OEM number A0255457232 is the correct reference for your engine code before ordering. A trained technician should carry out fitting, and ECU coding including immobiliser synchronisation and mixture adaptation will be required after installation. 14-day return period applies.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
