Response by BMW Australia regarding this issue...
"My technical department have advised that when the DSC light is off, the vehicle reverts back to a linier throttle response. When the DSC light is on, the vehicle will display an aggressive output. I hope this helps. For any further in information, I recommend that you speak directly with your service department."
I have responded
"Thank you although why does the sport light stay on if it reverts back to normal?? It defeats the purpose of an aggressive throttle response if DSC cuts in...
The enjoyment driving experience that BMW always advertises is lost with this setup..."
Awaiting their reply!!!
