I recently started to have that issue: I can't get into Tiptronic mode. I can't even get in "D", it get's in "D" only when I get in "4". Until now I haven't had any problems getting in "R" though. As anyone had this kind of issues, or does anyone know what can be done to fix this. I am hoping this may just be some small adjustments because other than that the car runs perfectly and the tranny seems to shift properly and everything. BTW it's a Jetta 02 1.8T
Thanks guys !
