Recently purchased a 2014 750Li with stock 19 inch Msport wheels.
Took in for service about a month ago for braking vibration during high-speed. the service center changed 4 pads and verified all rotors met the minimum thickness. But after the new pads, it started with noise when braking high speed, ( above 70mph) see the video below:

btw, i have already driven around 900 miles on these new pads
