Passenger cars (Mitsubishi eK and other models) - Repair

An official CAA Japan notice concerns Passenger cars (Mitsubishi eK and other models) - Repair. Due to engine defects. ■Defective components (part names): ① Engine (EGR cooler, EGR valve housing). ② Engine (engine control unit (engine ECU), fuel pump, spark plugs). ■Description and cause of the structure, equipment or performance deemed noncompliant with standards: ① Some materials used in the exhaust gas recirculation (EGR) system's EGR cooler and EGR valve housing are unsuitable and may corrode due to exhaust gas condensate. Corrosion fragments may become trapped in the EGR valve, or holes may develop in the EGR valve housing. This may cause poor combustion, engine stalling and inability to restart. ② Due to improper control of fuel flow during fuel pump manufacture, some pumps have insufficient fuel flow. In addition, an unsuitable control program in the engine control unit (engine ECU) may cause excessive fuel injection. Together with unsuitable spark plug specifications, these conditions may cause spark plug fouling, resulting in prolonged starting times or inability to start. Published 2015-09-03.
What to do now
(Recall) 3629 ■Corrective measures: ① On all vehicles, check the EGR cooler and replace it with a modified part. Also replace the EGR valve housing with a modified part on all vehicles. ② Update the engine ECU program on all vehicles with the corrected version. Where improvements to the fuel pump and spark plugs are required depending on vehicle variant, check the fuel pump and spark plugs, replace the fuel pump with a defect-free part, and replace the spark plugs with parts of revised specifications.
