Description
OEM number A0285454432 identifies this genuine used and tested Engine ECU Control Module for the Mercedes-Benz S-Class W220 (1998–2005). Extracted from a written-off W220 donor, it has been confirmed operational before listing, offering a cost-effective alternative to a new unit for one of Mercedes-Benz’s most sophisticated saloons.
The W220 S-Class represented the pinnacle of Mercedes-Benz engineering at the time, and its ECM managed the complex interplay between the V6, V8, or V12 engine variants and an array of luxury and safety systems. The ECM regulated injection, ignition, cylinder deactivation on applicable V8 models, and communication with the COMAND and AIRMATIC networks.
ECU faults on the W220 can manifest in a range of ways, including misfires across one or more cylinders, a rough idle that fluctuates at traffic lights, loss of adaptive cruise control integration, or suspension-related fault codes stemming from ECM CAN bus communication errors. Starting issues in cold weather are also reported.
Tested prior to dispatch and removed from a written-off S-Class, this module is listed under OEM reference A0285454432. Verify this against your existing part carefully. The W220’s complex electronic systems require a Mercedes specialist and XENTRY coding equipment for a successful installation. A 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.
