Coding Tiptronic control unit
Information
  • The adaptation values must be reset using the PIWIS Tester 9718 when the transmission is renewed/replaced.
  • 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 PIWIS Tester 9718 have highest priority.
  • The procedure described here has been structured generally, changes or additions may be displayed.
  • The PIWIS Tester 9718 instructions take precedence and in the event of a discrepancy these are the instructions that must be followed. Deviations may occur with later software versions.
  • During coding, it is essential to guarantee the power supply for the PIWIS Tester 9718. It is essential to connect a battery charger with a current rating of at least 40 A to the vehicle battery.
