Thanks. That sounds like the same issue my buddy had in his M5 - a thunk when he let off the gas or brake pedal. Which ended up being the rear differential needing to be replaced as well. I heard the noise coming from his car and its nothing like what I am experiencing. Although the hollow clicking noise you describe from outside the car does sound a bit more relatable. I'm going to bring up the differential issue to BMW and even see if I can get a mechanic to take a ride with me to verify what the noise is (hopefully).
Thanks again for the insight, appreciate it.
