audi norway a6

Today my tranmission started messing up after 40 min driving. i got the prnds lights blinking. all the letters are blinking simultaneous. And the car shutters at take of. if i leave the car to sit for an hour, then it works fine again until it warms up and the fault comes back. the car has only run 178000km or 110604.07 Miles so i cant imagine the transmission is worn out. i bought the car only 4 weeks ago, and it has full service history.
i have been thinking can it be the transmission oil ? any ideas ? Greetings from Norway.
