Covers for the seat rails? I dont think I have seen those in any mk7 I have seen.
Correct. They snap onto the ends of the seat rails.
And they BUZZ. The sort of hard buzz older VW cars were known for, like a big fly banging on glass, triggered by slightly rough asphalt, or the heavy bass line on the intro to Headstones track 'Unsound', from their 1995 album 'Teeth & Tissue'.
I've been chasing that buzz since last fall. I shit you not I commute 3 hours a day, and it was making me insane. It sounded like it was coming from somewhere near where the back seats meet the body, or the rear hatch or headliner, rear passenger door, or some other nightmare location that I couldn't reach from the driver's seat.
One day I spotted a dime sitting in the inside passenger rail, and thought for sure I found it. I didn't, but when I went searching for more coins I hooked a fingernail on one of these, and the sound it made was mocking. The second I hit the road after I yanked them out I knew I could enjoy a silent commute at last.
If you have a buzz or rattle that won't go away, despite having spent precious time screwing around with that mystery of Teutonic revenge design that is the console lid, I encourage you to pry these off, destroy them for all time, and join me in saying a prayer to the gods of justice that the one who approved these parts loses all their teeth and goes blind before shitting themself to death.
