I have the Altea which is it's relative and it's pretty good to drive. The gear box is a dream. You would not want to drive it using paddles that just a motoring correspondents stunt - it doesn't have paddles. I keep mine in Normal mode, you can move into Sport and it changes up sooner [think it's up
]. It's handy in a round about system of a new town where if you got the urge you can whiss around. I only put it in low gear by hand when going down a hill in Germany !, other than that in auto. You use the gear stick to change gear in manual mode. The whole shift moves to the left then you click up and down to get it to shift. As said, only do that twice a year.
It's good in heavy motorway trafic when your crawling, none of that changing up and down which wears your arm out. Think that's about it. I've had no problems with the DSG and I've had it a year now.
