Hi I recently purchased a 2016 3 series 2 days ago from a bigger dealership and now my car has a bad grinding noise and pops as soon as I put the brakes on and now won’t let me drive forward, it started out as a clunking noise now I can only reverse with minimal grinding noises. Currently parked at my house, about to call dealer. Any suggestions or possibilities on what this could be?
Did you drive it in a spirited manner during your two days of ownership? The guibo (drive shaft flex disk) may have let go; or hydraulic motor mounts could have failed… or something else rubber bushing in the driveline…. May sound worse than it is.
