Mk2 TFSI 2.0 VRS Octavia

Hello everyone,

i have a technical question about my octavia tfsi turbo. When Im driving at around 100kph+ I notice a whistling sound (similar to something cutting the air wrong). I did at first think it was the rubber above the windshield which was a bit loose but i fixed that problem. After a highway drive I still notice the whistling sound which is noticeable but its not soo loud you would thing something is gonna fall apart.

If any of you maybe have the same issue or know what might be loose or wrong, would appreciate the advice. I know on diesels the whistling/whining noise is from the turbo but i doubt that would be the problem on the petrols.

Some images of my rocket.

Thanks for the help and cheers :)
