Vibration at high speed

franksinatra · 09-14-2021, 09:44 PM

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.

Might also be the center support bearing.

Where is the vibration felt? Seat? Steering wheel? front end?

could be any of the above, maybe try a wheel/tire re-balance?
