On mine too....
DS is "Dangerously SPECTACULAR"....!
Had it on my '06 330i and it was sooo much fun...automatically put a smile on my face....and then we get the "growling" noises of the engine.....in fact the demo 3.0 that I drove before arrival of my E70, had an AMAZING grunt in DS mode ,almost like a 4.8 !....I think that had broken in already.!

So I thought what could be better...a 3.0 and 4.8 rolled into one !
