After my engine was rebuilt due to cam chain jump and associated damage the Knock Sensor fault would come on every time I went for a ride. Sometimes right away sometimes after 100 miles but it would always trigger at some point. Dealer spent lots of time on the phone with BMW and taking things apart but could never get the fault figured out. I always assumed "Knock" had to do with detonation or ping but according to them it does not. It is some kind of resonance or audible issue, Didn't make any sense to me. I sold it cheap on ebay and disclosed this to the new owner. It would be interesting to know if it ever got rectified. Good luck.
