Question New 540i engine rough and misses on cold start

The first start of the day I experience a rough fast idle which actually shakes the car until the idle speed drops to normal. Passengers have remarked "what's wrong with your car?"
Been back to the dealer and they have felt it and seen it. Car has only 1500 miles. Tried new plugs, new coils and a software update but nothing helps. Now the factory rep states this is "normal".
Does anyone else have this issue? Please help!
Thanks much.
