If you feel and hear a loud “thud” coming from the rear area of your BMW when first accelerating away from a stop, most like the differential carrier bushing is worn or has failed. It is highly recommended that a bad or failed differential bushing be replaced right away! Failure to do so can result in differential, drive shaft, or sub frame damage. To prevent costly repairs, replace the carrier bushing at the first sign of wear!
