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