Just to make you aware that there have been rumours that using launch control too many times in a short space of time can over stress/over heat the clutch plates on the gear box. Whether this is entirely true im not sure, im sure i read it on a vw forum.
My edition 30 has launch control and in the 3 years of ownership i have never used it. I bet other dsg users have used it over and over again with no problems, i just havent risked it lol
