That is not compressor surge. Compressor surge only happens under load when the turbo is near peak efficiency. See Kevin's video.
Your BOV is fluttering, but it's nothing to worry about as long as it holds boost. You can screw down the bolt on top of the BOV to give it more tension and that will help prevent the fluttering and cause it to only be open or closed. To be honest, as long as the car runs fine, drives fine and the BOV doesn't leak then it can act however it wants.
