I was encountering the same problem on my 190E till I went to bleed the brakes. When I was loosening all of the lug bolts I noticed none of them were the same in tightness. When I put the wheels back on I made sure I used a torque wrench. Took it for a drive and no more vibration. Maybe the differences in torque on the lug nuts was causing some warpage in the rotors or wheels? I don't know but my vibration is gone now.
