Odd vibrations

[lemans4.8]

I'm having odd vibrations when my '05 X5 4.8 is at a stop. I can feel the vibrations through the floorboards and in the seats. It's does this more in the cold. What do you guys think the problem is? Think it has to do with my steering pump?

I think that's just the rumble of the engine, mine does it too especially when it's cold out

I have a similar issue and it has turned out to only be noticable in cold weather whenI have the A/C turned off. If the vibrations go away if you turn the A/C on, then you've isolated the problem to the set idle level. Not sure if the idle rpm can be changed due to an apparent lack of an idle control valve (or at least that's what the tech at Edmonton BMW told me).

Any inputs??
