Mercedes-Benz S 580/Maybach S 580 4MATIC engine control unit software error affects lambda control

Country	South Korea
Category	Automotive
Published	2025-03-07
Manufacturer	Mercedes-Benz Korea Co., Ltd.
Models affected	S 580 4MATIC , Maybach S 580 4MATIC
Units affected	4289
Defect	Due to a software development process error, the lambda control in the engine control unit software may not operate normally. In such cases, the amount of fuel injected by the lambda control system may increase, leading to a rise in exhaust temperature and potential damage to surrounding components (e.g., engine wiring, catalytic converter). This could result in a loss of propulsion without prior warning, and the possibility of fire cannot be ruled out, leading to this recall.
Component	Engine (Power Generating System) Other
Remedy	Update the improved engine control unit software and replace damaged wiring or catalytic converter if necessary.
