I have not had a serious problem with a Tiptronic, so I have not gone deep into it. I have had the flashing D-4 ('limp mode') a couple times. Once was a shift lever that had been damaged and did not position correctly to the Drive position, the other was low voltage from a weak battery. Find out what is wrong before putting a lot of miles on.
I'd recommend using a code scanner that can read transmission codes on Porsche. I use an older Autel which I like because it works on a wide variety of cars and doesn't require a computer. Foxwell seems like a popular one now and Durametric is recommended by many. I don't have a recommendation other than making sure that it can read Porsche specific modules and that it provides information that YOU can understand and use.
