Attention E60 M5 owners this normal?

Do you all have a simulair whine in the back ground blipping the throttle? Hard throttle the noise blends into the background.

Could do with knowing, don't want to be kicking the dealer who sold me the car for no reason.

Ant, is that from cold? If so, I'm pretty sure mine does that too.

Cold and when warmed up.

yep mine too - think its just all the pullys and belts?

As you say probably still there on hard throttle but the engine noise masks it.
