Hello all, I just had my car for a week and now I hear a whistle noise or kind of bird noise (only one time) after a cold start. Sounds like valve or something closes after the ticking noise has gone (after engine warmed up). You can hear it in my video at second 13.
Is it normal? I never notice it in my 991.2 c4s
P.S. I am not concerning ticking noise
