strange noise inside

Hello I was sitting today on the back seats of my car and I heard a noise like something was rotating and this looks only to appear at around 100 km/h. It is a w203 200 cdi 2002 and it looks like it's coming around the propshaft under the back seats(I think) and it doesn't look like a wheel bearing noise. Any help?

Did you check the driveshaft to see if any of the components were loose, such as the driveshaft center support? Get it on a lift or get the back end of the car in the air on jack stands (make sure you use jack stands, NEVER trust a jack to hold up a vehicle while you are underneath it). Go under the car and move the driveshaft around to see if there is play anywhere. When you move the driveshaft, don't just turn it - move it side to side and up and down too.

check for 'play' in the drive shaft - center support bearing and flex disc/guibo.
