Yeah. Must be. We got a second 535i for our house hold today (Non M-sport) but with the DDC. Had the same shake my M-sport did when new, but not as bad. Must be something with the car having to settle after around 2,000 miles. My M-sport is super smooth now. I am sure the 2nd 535i we just bought will have the same fate.
