Dear All,
I have traded my 97 S500 to a 97 S600. The S600 got the ESP instead of the ASR. Finally I have a chance to test the ESP because of the weather.

For my S500 with ASR, when I hit the gas after traffic light, the wheel will spin, then ASR come and cut engine power (wheel stop spinning) and I can see the yellow triangle flashing in the center of the speedometer.

For the S600, I did the same thing, the wheel still spinning, the rpm hit almost 5000, no yellow triangle but the car is going straight but the wheel is still spinning.

I would like to know what is the different between ASR and ESP. is my situation normal? I also try a to hit the gas a little harder when turning into a corner, I can hear the wheel spinning but the car still turning to the direction i wanted, also no warning yellow triangle.

I can only see the yellow triangle on when I turn off the ESP or b4 fire up the engine.
