This makes sense when you think about it. Cars have computers and computers have always had hidden Easter eggs and cheat codes, so it was inevitable that someone would find a cheat code hidden inside a car. Case in point: here’s way to disable the traction/skid control systems called VDIM on the Lexus IS:
“start the car with the parking brake on ….then foot brake twice….(keep the foot brake down)….then parking brake twice (keep it down )and repeat till skid light is on the dash…..it will reset when you restart the car”
Apparently, this disables everything but the ABS. Source: VWVortex Forums via Digg
