If a DSG malfunction is detected, first of all, make sure that there are no leaks of its working fluids (see chapter 1). The vehicle owner can check / replace the information sensors of the DSG control system. Before proceeding with the replacement of the suspected sensor, poll the memory of the control unit - all any significant failures are recorded in the memory of the DSG control module in the form of fault codes (DTC), and in particularly serious cases, the DSG automatically switches to emergency operation mode. DTCs are read using special diagnostic equipment connected to the on-board self-diagnosis system connector (DLC), - see chapter 5. In the absence of access to the necessary devices, it will be enough to try to at least qualitatively determine the nature of the failure (electrical/mechanical) in order to facilitate communication with car service specialists. You should not prematurely start removing the DSG, since its diagnosis is only possible in the established position.
