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.
