I have a noticeable 'hum' sound coming from what seems to be the transmission or engine when driving at slow speeds. I know it is not my runflats as I can hear the pitch of the hum changing when the car shifts gears. Is this just normal engine and/or transmission noise? Does anyone else notice this or is this just the way the car sounds at low speeds?
The sound is not there at speeds above 60mph.

I sometimes have the humming sound when the engine is cold and I am waiting at a traffic light near home.. it goes hummmmm and then nothing and then hummmm again.. A bit strange but not irritating enough to ask my dealer.

Try cutting off your ac and see if it makes a difference.

Steptronic. I'm REALLY getting sick of this car. Now I notice the car shifts rough too in the morning when it's cold - VIBRATION. The sad thing is, it is hard for me to reproduce the problems, since they are intermittent. I'm sorry, but this car does not feel nor act like a 50K + car. I'm ready to sell it and go buy a freaking Lexus or new RL.

lifes too short to get too stressed over this....sounds like you might have an issue, if it only happens when the engine is cold then the dealer should be sorting out a loan car and booking your car in for 2 days so that they can keep it overnight and test drive from cold. if they have not suggested this then suggest it to them!
i have not really noticed that my E60 steptronic is really that much different when cold but then i always allow a car a few quirks while it warms up, once the engine has reached normal temp and the little white bars on the rev counter have gone down all should be fine.
have you ever tried driving an M3 from cold? they sound like someone has swapped the exhaust for tin cans and put a bag of nails under the bonnet in place of the engine...but once warmed up Vrooooooooooom.
good luck
