Can hear a whining metal sound coming from below the car as the differential spins to power the back wheels. It probably is grinding itself to pieces and eventually will crap out. Sucks that I have good hearing and can hear it, most people don't notice it, but at night when its quiet I'm pretty sure people can hear it whistling and grinding as I drive around. This is the best looking BMW yet has the most problems, not a good trade off.
