An official CAA Japan notice concerns Passenger cars (Audi A1 1.4/90kw and others) - Repair. Automatic transmission hydraulic control system (mechatronics) defect. ■ Defective part (component name): Automatic transmission hydraulic control system (mechatronics). ■ Details and cause of the structure, equipment or performance considered noncompliant with standards: In the mechatronics of the 7-speed S tronic automatic transmission, inadequate machining precision of the housing at the accumulator mounting point may cause fine cracks to develop in the housing when large hydraulic pressure fluctuations occur repeatedly, such as during starting or driving in congested traffic. As a result, hydraulic pressure drops and the warning light illuminates. Continued use in this condition could, in the worst case, leave the vehicle unable to drive. Published 2020-08-26.
What to do now
(Recall) 外-3079 ■ Remedial measures: On all vehicles, reprogram the automatic transmission control computer with the corrective software. If a fault code indicating low hydraulic pressure has been recorded, also replace the mechatronics.
