tiptronic limp mode

[wikan]

looking for help on auto transmission the alternating lights, no manual "paddle" function.
Car shifts and acts just perfect except for no paddle shifting and dash lights alternate between 4th and whatever gear the car is actually in.
Indicator telltale lights act perfect as long as the engine isn't running.
As soon as I start the car, telltales misbehave.
Have adjusted cable till I'm blue in the face!
Does anyone have any ideas???
