I had the same "surging" you are experiencing and my tech at BMW thought the clutch was tryigng to lock in and out of 4thr and 5th gear so rapldly that the surge was the sympton I was experiencing. He found that it went away in the sport mode due to diferent pressures in the transmission when the sport mode is engaged. I ended up having the transmission serviced and the filter changed out and the surge has gone away. Can't tell if it was low fluid or just worn fluid. My last service was done at 107k and now this service was just done at 185k....so almost 80k on that service.
