I tried doing launch control for the 2nd time the other day. Made sure the car was up to temperature, traction control off, in dynamic and S on the gearbox, etc. However, when I put my foot on the brake and then place my foot on the accelerator, the rev's do not move and the car just makes a kind of quiet beep noise (nothing comes up on the screen, etc). I let off the brake and tried again, it does the same thing. Then third time lucky it just comes to life, hits 4k revs and off I go. Am I doing something wrong or have any of you seen this before?
