Information
The procedure described must be applied when a control unit has to be replaced and the tester function Control unit replacement cannot be used.
Information
^ When the transmission is renewed/replaced, the adaptation values must be reset using the PIWIS tester 9718. It is expected that this function will not be implemented until tester software V8.0 is available:
^ Resetting adaptation values:
^ In the Tiptronic control module, select menu item Reset adaptation values and continue with >>.
^ Confirm with F7 for Yes, F8 for No and continue with >>.
^ Follow the instructions on the Tester.
^ If a new control unit is installed, it must adapt first. Poor shifting quality can therefore be expected in the adaptation phase.
^ After the test drive, let the engine run for 10 minutes at idle speed. This ensures that all adaptation values are stored in the control unit.
^ The instructions of the Porsche System Tester have highest priority.
^ The procedure listed has been structured generally; changes or additions may occur.
