Vibration at high speed

Not sure what this could be. Accelerating or decelerating causes the issue at high speed, not noticeable at low speeds.

If I set cruise control to a certain speed, say 130km/h, the car is okay as long as cruise stays on at that speed. But if I cancel the cruise control and the car decelerates, there is a vibration felt in the vehicle (through the seats not through the steering wheel).

What could cause something like that? Vehicle is a 2011 328xi sedan.

Sounds like your Guibo (Flex disk) is going bad. Pretty easy to replace.
