An official CAA Japan notice concerns Passenger cars (Mercedes-Benz E220d station wagon, CLS220d) - Repair. Engine (coolant pump) defect. ■ Defective component (part name): Engine (coolant pump). ■ Condition and cause of the structure, equipment or performance deemed noncompliant with standards: Due to an inappropriate bearing seal design in the coolant pump installed in the diesel engine, coolant may enter the vacuum circuit that controls its operation, causing related vacuum circuit components to malfunction. This may cause the engine warning light (MIL) to illuminate, reduce engine output, impair brake booster function, or cause other malfunctions. If the solenoid valve controlling the exhaust gas recirculation (EGR) system malfunctions, the MIL will illuminate and exhaust emissions will worsen. If a short circuit also occurs, heat may be generated and melt surrounding components, potentially causing a fire in the worst case. Published 2022-04-27.
What to do now
(Recall) 外-3397 ■ Corrective measures: On all vehicles, replace the EGR control solenoid valve with a new one and reprogram the engine control unit with the corrective control program. Also inspect the vacuum circuit and replace related components into which coolant or engine oil has entered with new ones.
