I have a 2017 M2 DSG with 108k miles and a weird vibration. It starts at about 60 mph and gets better around 75. It’s an oscillating vibration that I don’t feel in the steering wheel and doesn’t seem to be associated with braking. I had both rear tires road force balanced but it didn’t help. I’ve gotten all the wheels off the ground, spun them, and moved side to side and top to bottom and the bearings feel ok. I’m wondering if any here know of other common things that might cause this. Thanks for your help!
