An official CAA Japan notice concerns Passenger cars (Mercedes-Benz C220d and 7 other models) - Repair. Engine (coolant pump) defect. ■ Defective part (component name): Engine (coolant pump). ■ Condition of the structure, equipment, or performance considered noncompliant with standards, and its cause: In coolant pumps installed in diesel engines, an inappropriate bearing seal design may allow coolant to enter the vacuum circuit used to control operation, causing associated vacuum circuit components to malfunction. This may cause problems such as illumination of the engine malfunction indicator lamp (MIL), reduced power output, or reduced brake booster function. If the solenoid valve controlling exhaust gas recirculation (EGR) 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 2022-09-14.
What to do now
(Recall notification number) 外-3469. ■ Remedial measures: On all vehicles, replace the EGR control solenoid valve with a new one and rewrite the engine control unit software with the remedial program. Also inspect the vacuum circuit and replace any associated components into which coolant or engine oil has entered with new ones.
