so this phantom sound, does it sound metallic? or maybe like plastic hitting, bumping, creaking or tinny? What is your best description of the type of sound?

Could it be coming from under the car in the damper or shock area? I have seen where the boots for shocks come loose and cause a thud sound when you roll over a bump. it doesnt sound metallic.

If it sound creaky like the body is flexing I would wonder if a spot weld broke or something. That brings me back to the days of the Z3 rear floor pan issue which was known to be an issue and required extensive welding to reinforce.

I dont mean to scare you either this is not likely an issue like that.
