Sometimes car bogs down (throttle closed ?) but no DTC light

Hi,

I noticed a strange phenomenon which happens since...forever. On less than perfect surfaces, car acts like the DTC kicks in (throttle is closed at high rpm like over 3500RPM especially in second gear) but I can't see the yellow light blinking. This happens with both the DTC button not pressed or pressed shortly. When everything is deactivated by long-pressing the DTC button, it does not seem to happen but there is no way to tell for sure.

Maybe the yellow light is only for DSC (stability control) and the traction control does NOT blink that light when it kicks in ? This may explain why some people with LSD installed feel a much better acceleration.
