968 – Tiptronic – kaputt ??

  • The car is 1992 968convertible
    with 100Kkm's. Otherwise in excellent condition but there are currently
    Tiptronic problems.





    When cruising slowly in city speeds no problem but when you step on it, car
    hesitates to take more than 3K rpm's. Then it start to "brake" and
    you are not able to add any revs. When you release gas, it will act normally.


    Also same kind of problem when you try to select gears manually; when revs rise
    car will stumble. If you try to acclerate several times, the
    "Tiptronic" light will ligtht up and it shows only "D" in
    dashboard, not a gear in which the car was. I suppose car is then in the safety
    mode and it has locked gear 4 as it does when it goes to safety mode. If you
    have played several times with it, you can reset it and have all the gears back
    by restarting the car. If you are not lucky only 2 & R are there.



    Oil level has been checked which was low. Oil was added according to
    WSM and it made some progress to better. Does the low voltage effect
    to Tiptronic's functions. Currently charging is too low, about 12V. New voltage regulator will be installed, soon.




    All advice would be great !

  • Same with me,
    I would realy like to help but I have no idea how (it´s not a question of language), but my 968 has got a "real" gear box.
    Realy hope you will find a solution.

  • Hi Sauli,


    die Tiptronic braucht Strom. Bei mir war der Keilriemen lose/alt und die Lichtmaschine hat die Batterie nicht richtig geladen. Dann hatte ich gleiche Probleme, bis gar nichts mehr ging.


    Wie alt ist bei dir der Keilriemen, der die Lichtmaschine antreibt?

  • I`ll try to translate:


    the Tiptronic needs current (edited by administrator). With me the fan belt was loose / old and the alternator did not charge the battery properly. Then I had the same problems, until nothing at all worked.


    How old is the alternator belt?

  • Hi Sauli,


    can you please let us know if fitment of the new voltage regulator shows any improvement ?
    If it doesn`t I would suggest to contact your nearest Porsche dealer and perform a fault memory check of the TipTronic ECU.


    Are you aware of the workshop manual and its detailed trouble shooting procedure ?



    Cheers :wink:
