I have heard people say that the MK6 GTI has launch control if you option on the DSG Gearbox.

How do you enable this? is it a simple press (or hold down) of a button? Do you just put it into sport mode, hold down the brake and accelerator and let go of the brake?

And does it void the warranty?

I know on the BMW M3 and Nissan GTR that after a certain amount of attempts, it voids the cars warranty. Is it the same case with the GTI?

And has anyone here actually performed this on their MK6 GTI?
