I have a 2020 MK7.5 GTI DSG-7. I have notice since last week that now I can hear a noise coming from my engine bay, the noise I hear is the one that you would associate to a "Blow-off" valve venting to atmosphere. I have 20K miles on it and I have never heard that noise happened before. I have read that our GTI's have a diverter valve instead a Blow-off valve. Can this new noise be an issue with my diverter valve or could it be some other reason, like a busted or lose charge pipe? I have an enclosed VW Raceline R600 intake.
