This is exactly what I did and my cold start knock went away. I did this months ago just as preventative maintenance a few months ago and my car felt smoother as well as the knock noise going away on cold start. Funny thing is I wasn’t even trying to fix the knock lol. So I guess the fix found it’s way to me. But yeah definitely try the Vanos and clean both solenoids.
