An official CAA Japan notice concerns Passenger cars (Mercedes-Benz E220d and 10 other models) - Repair. Engine (coolant pump) defect. ■ Defective component: Engine (coolant pump). ■ Condition of the structure, equipment, or performance deemed noncompliant with standards and its cause: Due to an inappropriate bearing seal design in the coolant pump installed in diesel engines, coolant may enter the vacuum circuit that controls operation, causing associated vacuum circuit components to malfunction. This may cause the engine warning light (MIL) to illuminate, reduced power output, reduced brake booster function, and other problems. If the solenoid valve controlling the exhaust gas recirculation (EGR) system malfunctions, the MIL illuminates and exhaust emissions deteriorate. If a short circuit also occurs, heat may melt and damage surrounding components and, in the worst case, cause a fire. Published 2022-06-30.
What to do now
(Recall notification number) 外-3439 ■ Corrective measures: On all vehicles, replace the EGR control solenoid valve with a new one and rewrite the engine control unit software with the corrective program. Also inspect the vacuum circuit and replace any associated components into which coolant or engine oil has entered with new ones.
