An official CAA Japan notice concerns Passenger cars (Mercedes-Benz E220d and 4 other models) - Repair. Defect in the engine (coolant pump). ■ Defective component: Engine (coolant pump). ■ Condition of the structure, equipment or performance considered noncompliant with standards and its cause: Due to an inadequate bearing seal design in the coolant pumps fitted to diesel engines, coolant may enter the vacuum circuit used to control operation, causing related components in that circuit to malfunction. This may cause the engine malfunction indicator lamp (MIL) to illuminate, reduce engine power, impair brake booster performance, or cause other malfunctions. If the solenoid valve controlling the exhaust gas recirculation (EGR) system malfunctions, the MIL illuminates and exhaust emissions deteriorate. If a short circuit then occurs, heat may melt surrounding parts and, in the worst case, cause a fire. Published 2022-05-25.
What to do now
(Recall) 外-3412 ■ Remedy: On all vehicles, replace the EGR control solenoid valve with a new one and reprogram the engine control unit with remedial software. Also inspect the vacuum circuit and replace any related components into which coolant or engine oil has entered with new ones.
