90520859, S98002-06 MD Opel ASTRA G 2.0 DI Motor Ecu Kontrol Modülü – Orijinal İkinci El & Test Edilmiş

Açıklama

The [[Opel]] Astra G 2.0 DI occupied a distinctive position in the Astra range, offering direct petrol injection technology — an advanced approach for its era — in a compact body that had already proven its mainstream appeal from 1998 to 2004. This engine control module, carrying dual OEM references 90520859 and S98002-06 (suffix MD), is the original unit engineered to manage the 2.0 DI engine’s direct-injection combustion cycle. ¶ Direct injection petrol management places greater computational demands on the ECU than conventional port injection, requiring the 90520859 / S98002-06 MD unit to handle high-pressure fuel rail control, precise injection timing into the combustion chamber, charge stratification strategy and enhanced knock sensing. This module co-ordinates those functions alongside ignition timing, idle regulation and closed-loop emissions control to deliver the efficiency and power characteristics intended by Opel’s engineers. ¶ Sourced from a professionally dismantled Astra G 2.0 DI, this dual-referenced ECU has been bench-tested to confirm correct functional response and is supplied in clean, serviceable condition. The twin OEM references reflect cross-market homologation — both numbers identify the same production unit with identical specification. ¶ Verify either OEM reference — 90520859 or S98002-06, suffix MD — against the module currently fitted to your vehicle. Given the specialised nature of the 2.0 DI injection system, professional coding and adaptation using appropriate Opel diagnostic equipment is strongly advised following installation.
