Information
Due to the assembly process, particulates can stick to components in rare cases during production of
the double clutch transmission (PDK). As a result, there is a possibility that some control valves in the PDK
control unit can become jammed or malfunctions can occur.
Action required: In the event of a customer complaint, first clean the ATF lines and ATF cooler of the Porsche Doppelkupplungsgetriebes (PDK).
If the error message still exists, the PDK control unit must be replaced.
