It doesn't have launch control but first gear is feeble so it kind of works well for getting the power down. 2nd on the other hand ;)
 
No lauch control, but can be activated with VAG-Com (i dont know how but i have read it). They have disabled it because the DSG is too fragile.
 
I find the best way is to hold the car still on handbrake then floor it and let handbrake off together, as when u touch the brake the clutch goes in
 
As I said first gear is weak! Use that to get the car moving then the big guns come out in 2nd gear lol. It changes gear so rapidly you will make up a lot of time that way. Think its 3 changes to 60.
