'007 Audi S6 with V10:

The S6 has traction control and electronic stability control, which can be turned off in two stages: Press the ESP button once and the traction control is turned off. Holding the ESP button down for longer than three seconds turns off both traction control and the electronic stability control.

Do all Gallardo's & R8's have the same two stage ESP program?
