Hey everyone,

I’ve got a 08 E93 M3 with about 165k miles, DCT.

I was driving on the Highway today going about 80 mph and out of no where the car started vibrating terribly seemingly coming from the rear, I pulled over and observed the car and there seems to be no damage, ( I checked wheels, bumper, etc) after doing some research, it seems like it could be a plethora of things, but I guess to troubleshoot, has anyone experienced anything like this?

It’s fine under 40 mph but as soon as it hits 40 it starts to vibrate and gradually gets worse as the speed increases.

There is no change to the vibration on or off the gas, (once up to the aforementioned speed) and no change based on RPM either, I’m assuming this is likely driveshaft or CSB related?

Thanks
