Açıklama
OEM numarası 8D0907557C orijinal Audi A4 B5 Engine ECU Control Module, recovered from a written-off B5 platform car and bench-tested to confirm it meets the original Audi factory parameters. This unit is a direct OEM replacement for the correct engine and variant combination.
Acting as the central engine management controller for the A4 B5, this ECM coordinates fuel injection strategy, ignition timing advance, idle speed regulation, and exhaust emissions control. On TDI diesel applications it operates within the Bosch EDC15 diesel management system, optimising torque output and fuel economy across the full load range.
A deteriorating A4 B5 ECU may produce symptoms including a persistent engine fault light, irregular idle that hunts or fluctuates, flat acceleration, heavy TDI smoke at cold start, intermittent communication loss with diagnostic tools, or stored codes for fuel rail pressure deviation and injector output stages.
Offered as a used and tested unit. Always verify OEM number 8D0907557C matches your exact vehicle, engine, and year before ordering. Fitting by a qualified VAG specialist is strongly recommended. VCDS adaptation, immobiliser coding, and injection quantity calibration will be required. 14-day returns accepted.
