Hi everyone. I just bought a 1999 Passat v6 2.8l with tiptronic 5 speed transmission front wheel drive. The carpet on the passanger side was wet and the TCM was open, even the plastic box was broken. The transmission display shows all the positions highlighted (limp mode) for a brief periodo and then goes off, sometimes not even comes on, but when you disconnect the battery and reconect it again, first it shows is in 2nd, then R, then P, then N and then all. But I hear a little click sound and the "press brake" light on the selector lever pulsates along with the transmission display and then it goes off. As the TCM was already open, I dryed the dampness with some rice but nothing seems to change. The car is stuck in 3rd gear and everytime I change into R, I can feel a hard stump, the same as changing into D. Tiptronic does not seem to engage when I move the selector lever to the right and the transmission display stays off. Do I have to replace the TCM? As a note, sometimes i connect the obd2 diagnostic tool and it gave me P1626 code and sometimes does not show any codes at all.
