Rotational Thumping Sound

Lately, I've been noticing a rotational thumping kind of sound heard mostly between 25 - 30 mph coming from under the vehicle. It sounds like its coming from below the accelerator pedal. It doesn't matter if I'm coasting or accelerating (although it could be hear better when coasting due to normal engine sounds with acceleration).

When I took by 2011 X3 to the dealer, the tech heard it. Afterward the tech noted that similar X3 with similar mileage (mine has about 18,000 miles on it) could be heard making the same sound.

From what I've gathered online from different (and sometimes unrelated forums) is people mentioning the following as culprits but its like finding a needle in a haystack:

Wheel bearings
Transaxle
Axle shafts
CV Joint
Cracked brake rotor
Loose lug nuts
Broken tire belt
Drive Shaft
Loose brake pad
Warped Rotor
Transmission mounts
Engine Mounts
Wheel/rim
Transmission cover plugs in place

Anyone else experience this or have any suggestions?

I have 18.4k on my 2013 X3, so far, I haven't experienced any of the sound you are hearing.
