Coding Tiptronic Control Unit
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.
