Description
OEM number A0255453932. This genuine used and tested Engine ECU Module originates from a mercedes-benz“>Mercedes-Benz W210 E-Class (1995–2002). Carefully removed from a salvaged vehicle and verified against OEM factory standards, it was confirmed operational through functional testing prior to dispatch. ¶ Serving the W210 E-Class petrol engine, this module oversees sequential fuel injection management, ignition coil dwell time control, and closed-loop lambda regulation. It monitors exhaust gas composition via the upstream and downstream oxygen sensors, continuously trimming the fuel mixture to maintain stoichiometric combustion for emissions compliance and fuel efficiency. ¶ When degrading, this ECU may cause the engine to idle unevenly, stall unexpectedly, or produce a noticeable flat spot during acceleration. Cold-start enrichment may fail, resulting in a weak or flooded start. Fault codes for oxygen sensor switching, fuelling adaptation limits reached, or ignition coil primary circuit errors may appear under diagnostic interrogation. ¶ Removed from a written-off Mercedes-Benz W210 and verified in full working order before dispatch. Ensure OEM number A0255453932 is the correct match for your vehicle before purchasing. A qualified specialist should carry out installation, and ECU adaptation including variant coding and lambda sensor calibration is typically required. 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.
