An official CAA Japan notice concerns Passenger cars (Mercedes-Benz G350d and 3 other models) - Repair. Defect in the engine (coolant pump). 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 on the diesel engine, coolant may enter the vacuum circuit that controls its operation, causing associated vacuum circuit components to malfunction. This may cause problems such as illumination of the engine warning light (MIL), reduced power output, and reduced brake booster function. If the solenoid valve controlling the exhaust gas recirculation (EGR) system malfunctions, the MIL illuminates and exhaust emissions worsen. If a short circuit also occurs, heat may be generated and melt surrounding components, potentially resulting in a fire in the worst case. Published 2022-04-01.
What to do now
(Recall) 外-3366. Corrective measures: On all vehicles, replace the EGR control solenoid valve with a new one and rewrite the engine control unit control program with a remedial program. Also inspect the vacuum circuit and replace any associated components into which coolant or engine oil has entered with new ones.
