The manual mode on the s-tronic still automatically changes gears for you. It will kick down if you mash the throttle into the floor, it will change up at red line line and change down if the revs get too low. I don't have a problem with the red line, or the auto downshifts at low revs, but the kickdown thing is a pain in the backside. When in manual it won't let you change to gears that the clever gearbox thinks are not appropriate. For example, if you are cruising at 40mph in 4th gear it won't let you have 5th. You can keep clicking the paddle but it will ignore you. In my 8P 5th gear is the right gear for cruising at 40 on a level road, just over 1000rpm, what you have to do is accelerate to about 45, then it will allow you to change up to 5th, then let the car slow to 40 and it will keep you in 5th. How is that "manual"? Pulling away at junctions is a total nightmare (but I think this is mainly due to my DSG being an early model) and the drive train is clunky at slow speed, especially in manual mode. The automatic modes aren't great either. "D" hangs onto high gears too long and "S" is close to pointless unless you like constant kick downs.
I know I'm going to antagonise all the s-tronic fans on here, but I loved the gearbox for the first few months but over time it just got on my nerves, and after a while I ended up hating it and wishing I had to use my left leg.
