Troubleshooting 7-speed DSG transmission «OAM» (Skoda Superb B6)

If you detect a DSG malfunction, first of all, make sure that there are no leaks of its working fluids (see Chapter 1). The car owner can check/replace the information sensors of the DSG control system. Before starting to replace the suspected sensor, interrogate the control unit memory - all significant failures are recorded in the DSG control module memory as fault codes (DTC), and in particularly serious cases, the DSG automatically switches to emergency operation mode. DTC codes are read using special diagnostic equipment connected to the on-board diagnostic connector (DLC), - see Chapter 5. In the absence of access to the necessary devices, it will be sufficient 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 start removing the DSG prematurely, since its diagnostics are only possible in the installed position.
