An official CAA Japan notice concerns Passenger cars (Mercedes-Benz CLA200d and 6 other models) - Repair. Engine (oil separator) defect. ■ Defective part (component name): Engine (oil separator). ■ Condition of the structure, equipment, or performance considered noncompliant with standards and its cause: In the engine's crankcase ventilation system, the oil separator is improperly designed, allowing oil contained in blow-by gases to enter the intake system and adhere to and accumulate on the air mass meter. This may prevent accurate measurement of intake air volume, illuminating the engine warning light (MIL) and reducing power output. In the worst case, the engine may enter fail-safe mode (constant low engine speed), and exhaust emissions may exceed the specified limits. Published 2023-09-28.
What to do now
(Recall notification number) 外-3679 ■ Corrective measures: On all vehicles, replace the oil separator with an improved part and the air mass meter with a new part.
