An official CAA Japan notice concerns Passenger cars (Volkswagen VW Polo 1.2/77kW and others) - Repair. Automatic transmission hydraulic control system (mechatronics) defect. ■ Defective component: Automatic transmission hydraulic control system (mechatronics). ■ Conditions and causes of the structure, equipment or performance deemed noncompliant with standards: Due to inappropriate machining precision of the housing at the accumulator mounting area in the mechatronics of the 7-speed DSG automatic transmission, some housings may develop fine cracks when subjected to repeated large hydraulic pressure fluctuations, such as during starting or driving in traffic congestion. Consequently, hydraulic pressure drops and a warning light illuminates. Continued use in this condition may, in the worst case, leave the vehicle unable to be driven. Published 2020-04-02.
What to do now
(Recall) 外-2978 ■ Remedial measures: On all vehicles, reprogram the automatic transmission control computer with the remedial program. For some models, preparation of the remedial program requires time, so the measure will be implemented as soon as it is ready. Also, if a fault code indicating low hydraulic pressure has been recorded, replace the mechatronics components.
