2018 M4 F82 weird sound
2018 BMW M4 - Anyone knows what this sound is? I heard it around 10mph driving forward/reverse. The sound in the attached link is when I'm reversing. You can hear it at the 0.02-second mark.
https://www.dropbox.com/s/9ndbmb2ezp...80620.m4a?dl=0 Brought it to BMW dealer right away, and the SA mentioned there is a TSB for this. But I don't think it's the brake, this is when I pressed on the gas pedal. I don't hear the sound anymore after restarting the car. TSB Number: B340615 Grinding noise from rear brakes: pebbles, road grit, or other foreign materials caught between the brake protection plate and the brake disc may cause a disturbing noise in the rear axle area. |
