Description
The OEM reference A6401503491 identifies this as a genuine <a href="/brand/mercedes-benz“>Mercedes-Benz engine control module fitted to the W169 A-Class, the compact front-wheel-drive hatchback produced from 2004 to 2012. Extracted from a written-off vehicle and tested to verify its operational condition before listing. ¶ In the W169 A-Class, the ECU manages fuel metering for CDI diesel or petrol variants, co-ordinates with the CVT or automated manual gearbox, and handles start-stop system integration where fitted. It processes MAP and MAF sensor inputs to optimise injection across the urban driving cycles typical of a compact city car. ¶ Typical failure indicators include no-start conditions, frequent stalling at idle, loss of power on motorway entries, diagnostic codes referencing fuel pressure regulators or mass airflow sensors, and occasional refusal to engage start-stop. The MIL may illuminate persistently or intermittently. ¶ Removed from a written-off A-Class and confirmed operational through testing before dispatch. Ensure OEM number A6401503491 matches your original unit exactly. Fitting should be carried out by a specialist, as ECU programming and variant coding are typically required for the W169 platform.
