Hi (A3 1.4 TFSI sportback 2009, 63k, automatic) As we have just got the car, I was checking the service records and thought that the S-Tronic gearbox oil hadnt been changed at 38k. So phoned Audi and they checked (over the phone) and said its a sealed gearbox and the oil never needs changing. Sounds handy to me! I didnt even realise ours is 7 speed and not 6 speed! Why arnt they all made like this? any downsides? PS. flappy paddles were a bonus, and they work really well.
